The decade-old LinkedIn automator, now sold as STACKED in a desktop and a cloud edition

Dux-Soup is a LinkedIn automation tool that started as a Chrome extension and now sells its product as STACKED, powered by Dux-Soup, in two editions: STACKED local at $55 per seat a month, a desktop app for Mac and Windows that runs campaigns on your own machine, and STACKED cloud at $99, which runs the same automation on managed always-on infrastructure, with team seats and metered agency billing built on the same two editions.

Overview

Dux-Soup is the elder statesman of this category. It launched in 2015, celebrated ten years in 2025, claims more than 300,000 users, and is operated by Supertec BV, a Dutch entity founded by Will van der Sanden. In a market where tools are removed by LinkedIn enforcement every year, a decade of continuous operation is not a small claim, and it is the single strongest argument for buying it.

The product's structure is unusual and is the thing to understand before you compare prices. Dux-Soup is not one product at two price points; it is two genuinely different execution models. STACKED local at $55 is a desktop app for Mac and Windows that drives LinkedIn from your own machine, which means campaigns stop when that machine is off. STACKED cloud at $99 runs the same automation on managed infrastructure that stays on. Most vendors force you to choose an architecture when you choose a vendor. Dux-Soup lets you start on your own machine and move to the cloud when the machine-on constraint starts costing you, without changing tools or rebuilding campaigns. The old $14.99 Pro edition and the Chrome extension editions are no longer sold on the pricing page.

Feature depth is the same on both editions. Local gives you invitations with personalized notes, messaging, profile visits, post likes, endorsements, follows and InMail (up to twelve action types), unlimited concurrent drip campaigns with AI-personalized messages, campaign statistics, a lead management dashboard, contact management, five built-in safety controls, and the native CRM integrations. Cloud is Local plus always-on managed execution. With the cheap Pro edition gone, the entry price now buys the whole working product, which makes Dux-Soup easier to compare with competitors than it used to be.

The integration list is quietly the best in the category for a tool this old: native connectors to HubSpot, Salesforce, Pipedrive, Freshsales, SharpSpring, and HighLevel, plus Slack and Microsoft Teams for notifications, Zapier and Make for everything else, an API, and native hooks into Claude, ChatGPT, and Gemini for message generation. HighLevel in particular signals the same agency audience that Closely courts, and Microsoft Teams support is unusual enough to matter if your company runs on it.

Best for

Buyers who want a long-established vendor with a genuine upgrade path, starting at $55 on their own machine and moving to $99 cloud execution when unattended running becomes necessary, and teams whose CRM is HubSpot, Pipedrive, Salesforce, Freshsales, SharpSpring, or HighLevel and who want a native connector rather than a Zapier bridge.

Not the right fit for

Agencies who need to operate client accounts without touching the client's machine; only the cloud edition solves this, and at $99 per seat the economics are worse than Aimfox or HeyReach at scale.
Teams that need multichannel email in the same sequence; Dux-Soup is LinkedIn-only and has no email finder or email sending of its own.
Buyers who want the safety-first marketing posture of a dedicated country-matched residential IP per account; Dux-Soup's local edition uses your own connection by design and its cloud edition does not lead with that claim.
Anyone who wants a modern interface; ten years of accumulated product shows, and the experience feels like a mature tool rather than a new one.

How it works

1
On STACKED local you install the desktop app on a Mac or Windows machine and log into LinkedIn through it. Automation runs on your own machine and your own connection, so LinkedIn sees activity from the place you normally work rather than from a vendor datacentre, which removes a class of detection signal that cloud tools have to engineer around. The cost of that is absolute: nothing runs when the machine is off.
2
On STACKED cloud, the same automation runs on Dux-Soup's managed infrastructure with monitoring, so campaigns continue overnight and across time zones with your machine off. This is the edition to buy if the machine-on constraint is what is limiting you, and it is why the ladder exists.
3
Audiences come from LinkedIn or Sales Navigator search results, or CSV import. Both editions run those lists through drip campaigns: a visit, a personalized invitation, then a sequence of follow-up messages at intervals, with replies stopping the sequence and tags organizing the pipeline in the lead management dashboard.
4
Replies land in the central inbox on both editions, contacts sync natively to HubSpot, Salesforce, Pipedrive, Freshsales, SharpSpring, or HighLevel, notifications fire into Slack or Microsoft Teams, and Zapier, Make, or the API cover anything else. AI connectors to Claude, ChatGPT, and Gemini generate message copy from profile context.

Feature breakdown

24 features in 4 modules

Core LinkedIn actions

Available on both editions, from $55 a seat.

Personalized connection invitations: Invites carrying a note built from profile variables, sent in bulk from a scanned search or an imported list.
Messaging first-degree connections: Bulk messaging to your existing network, which costs nothing against LinkedIn's weekly invite allowance and is the lowest-risk campaign available.
Automated profile visits: Visits at a controlled rate to trigger the who-viewed-your-profile notification as a soft first touch.
Post likes as a warm-up action: Engages with a prospect's recent activity before contacting them, generating a notification without consuming an invite.
Profile tagging and notes: Tag and annotate profiles as you go, so segmentation happens during prospecting rather than in a spreadsheet afterwards.
Activity log: A record of every action taken and when, which is the first thing you check if LinkedIn issues a warning and the evidence you need to adjust your rates.
CSV export: Scanned profile data leaves in a standard file at any time, which is the base protection against ever being trapped in the tool.

Campaigns and pipeline

Included on both editions since the entry-level Pro edition was retired.

Unlimited drip campaigns: Multi-step sequences with configurable delays between steps and reply detection halting the sequence, with no cap on how many campaigns run.
Central inbox: Replies collected in one place with context rather than scattered through LinkedIn's own messaging, which is the difference between a sender and a workflow tool.
Lead management dashboard: A pipeline view of where each prospect sits, with tags and statuses, functioning as a lightweight CRM for people who do not want to sync to a real one.
Campaign statistics: Acceptance rate, reply rate, and step-level performance per campaign so you can tell which message actually works.
Contact management: Persistent contact records that accumulate across campaigns, with duplicate protection so the same person is not worked twice.
AI message generation: Native connections to Claude, ChatGPT, and Gemini for generating personalized message copy from profile context, which is a more open approach than vendors who lock you to one model.

Execution models

Two architectures under one subscription ladder, which few vendors here offer.

Desktop execution: STACKED local is a desktop app for Mac and Windows that drives LinkedIn from your own machine and connection, so there is no vendor datacentre login for LinkedIn to notice.
Cloud execution: The Cloud editions run the same automation on managed always-on infrastructure with vendor monitoring, so campaigns continue overnight and with your machine off.
Upgrade path without changing vendors: Start on your own machine at $55 and move to always-on at $99, keeping your data, campaigns, and integrations throughout. Most other vendors here force an architecture choice at purchase.
Five built-in safety controls: Dux-Soup advertises five built-in safety controls, including rate throttling, randomized delays, working-hours scheduling, and daily action ceilings, present on both editions rather than gated behind a premium tier.
Managed monitoring on Cloud: The vendor watches the running instance rather than leaving a stalled campaign to be discovered by you three days later.

Integrations

Genuinely the best native connector list in this category.

Native HubSpot, Salesforce, and Pipedrive: Direct connectors rather than Zapier bridges, syncing LinkedIn activity and contacts into the CRM as it happens.
Native Freshsales and SharpSpring: Two mid-market CRMs most competitors ignore entirely, which matters a great deal if that is what your business runs on.
Native HighLevel: The agency CRM of choice for a large slice of the small-business services market, supported directly.
Slack and Microsoft Teams: Campaign responses and notifications routed into your team's actual chat tool. Teams support is uncommon here and useful for Microsoft-centric companies.
Zapier and Make: No-code workflow builders covering everything the native list misses.
API: A documented API surface for partners and custom integrations, which is your insurance policy for getting data out on your own terms.

Use cases

4 documented

Consultant testing LinkedIn outreach for the first time

Not yet convinced the channel works, unwilling to pay platform prices to find out, but wanting a tool that will still be there in two years if it does.

The 14-day free trial of STACKED local proves the channel before any money moves, and at $55 a month the full campaign toolset is available from day one.

Sales team running HubSpot

LinkedIn conversations are invisible to the CRM, so the pipeline record is incomplete and the manager has no idea which reps are prospecting.

The native HubSpot connector pushes LinkedIn activity and contacts into the CRM automatically, and Slack or Teams notifications surface replies where the team already works.

Solo operator whose campaigns keep stalling overnight

The local edition works well but the laptop closes at 6pm, prospects in other time zones are missed, and campaigns take twice as long as planned.

STACKED cloud at $99 moves the same campaigns onto always-on managed infrastructure with monitoring, without changing tools or rebuilding sequences.

Small agency using HighLevel for client delivery

Client reporting lives in HighLevel and a LinkedIn tool that cannot feed it means manual data entry every week.

The native HighLevel connector syncs LinkedIn outcomes into the client's existing workspace, and STACKED agency bills only for the client accounts actively running, under one dashboard.

Pricing

from $55 per seat per month (STACKED local), or $41.25 per month billed annually

Per-seat pricing across two editions, local and cloud, with fixed prepaid or flexible metered seats for teams and metered billing for agencies; the edition determines the execution model.

Plan	Price	Includes
STACKED local	$55 per seat per month ($41.25 billed annually)	Desktop app for Mac and Windows, runs on your own machine Unlimited concurrent drip campaigns and campaign statistics AI-powered message personalization Lead and contact management with export Native CRM integrations (Slack, Salesforce, Zapier, Make and more) The whole campaign toolset at the entry price. Campaigns stop when the machine running the app is off.
STACKED cloud	$99 per seat per month ($74.17 billed annually)	Everything in Local Runs on managed, monitored infrastructure Start campaigns from anywhere Security and account management Runs continuously with your machine off Buy this when the machine-on constraint is what is limiting your results, not before.
Teams	$55 and $99 per seat per month, fixed prepaid or flexible metered seats	Shared campaigns and a team dashboard on Local Consolidated billing Cloud metered above five seats Volume discount of 10 percent per 10 seats, up to 50 percent The volume discount ladder is where team pricing actually becomes competitive.
STACKED agency	Metered per client account actively running; rate not published	Single dashboard across unlimited client accounts Pay only for accounts running in a given period Managed cloud infrastructure per account Dux-Soup no longer publishes an agency rate; model it from the Cloud seat price and ask for a quote.

Add-ons

LinkedIn Sales Navigator (Roughly $99 per user per month, paid to LinkedIn): Not required. Dux-Soup scans ordinary LinkedIn search results, so a free or Premium LinkedIn account is a workable setup.

Billing notes

Annual billing takes 25 percent off both editions, bringing Local to $41.25 and Cloud to $74.17 per seat per month.
Teams get 10 percent off per 10 seats, up to 50 percent, and choose fixed prepaid seats or flexible metered seats, which materially changes the arithmetic above a handful of seats and is not reflected in the headline per-seat price.
Modelled for one user, a realistic working setup is STACKED local at $55 per month with a free LinkedIn account, so $55 all in. Adding Sales Navigator takes it to roughly $154, but unlike most cloud competitors Dux-Soup genuinely does not need it.
Agency pricing is metered per active client account and the rate is no longer published; the old Cloud Agency figure of $371 for five seats has been withdrawn.
The $14.99 Pro price is still quoted in older comparisons around the web; that edition is no longer sold, and $55 is the real entry price.
The 14-day trial requires no credit card, so evaluating any edition costs nothing.

Value assessment: STACKED local at $55 is fair rather than cheap: you get unlimited drip campaigns, a lead dashboard, and the best native CRM connector list in the category, from a vendor with ten years of history, in exchange for accepting that campaigns only run while your machine is on. Cloud at $99 removes that constraint and is priced at the top of what a single-account tool can justify, since Closely covers three accounts for $127 and Aimfox covers twenty for $499. The place Dux-Soup wins decisively is the upgrade path: few vendors let you start on your own machine and end at managed cloud execution without changing tools, and for a buyer who genuinely does not know yet how far this channel will go, that optionality is worth paying for.

Entry price history

Plans were restructured on 26 September 2026, so the current entry price is not directly comparable with the earlier one.

Checked	Entry price	What happened
26 September 2026	$55	Not a price rise on any plan that still exists. Dux-Soup retired the $14.99 Pro edition and now sells the product as STACKED in a $55 desktop edition and a $99 cloud edition, so the cheapest plan on the page is the old Turbo price.
22 August 2026	$14.99	First recorded

Strengths & limitations

Strengths

Ten years of continuous operation and over 300,000 claimed users, which in a category where LinkedIn enforcement regularly removes vendors is the strongest available evidence of durability.
Two execution models under one ladder, so you can start on your own machine and move to managed cloud execution without changing vendors or rebuilding campaigns.
The best native CRM connector list here: HubSpot, Salesforce, Pipedrive, Freshsales, SharpSpring, and HighLevel directly, not through a Zapier bridge.
Slack and Microsoft Teams notifications, with Teams support being genuinely uncommon in this category.
Model-agnostic AI: native connections to Claude, ChatGPT, and Gemini for message generation rather than a single locked-in provider.
The local edition acts from your own machine and connection rather than a vendor datacentre, which removes the login-location risk cloud tools carry.
No Sales Navigator requirement, so total cost of ownership can genuinely be $55 a month for a working setup.
A 14-day trial with no credit card, plus published prices and self-serve signup on every edition including agency.

Limitations

The entry price rose in practice when the $14.99 Pro edition was retired: $55 a seat is now the least you can pay.
STACKED local stops the moment the machine running it is off. If unattended running matters, you are on the $99 cloud edition and comparing against a very different set of competitors.
No email finder, no email sending, and no multichannel sequencing at all. LinkedIn is the whole product.
Cloud at $99 per seat is expensive against multi-account cloud rivals, and the agency rate is no longer published, so agency economics cannot be compared without a quote.
The vendor does not lead with a dedicated country-matched residential IP claim for its Cloud edition the way Expandi and SalesRobot do, so buyers evaluating cloud execution on safety grounds should ask specifically how the IP is handled.
The interface shows its age, and the offer (two editions, fixed or flexible seats, metered agency billing, and a product renamed STACKED while the site stays Dux-Soup) takes real effort to navigate before you understand what you are buying.
Feature velocity is slower than newer entrants; voice messages, event-attendee extraction, and AI appointment agents that competitors ship are not part of the product.

Head-to-head comparisons

5 alternatives

Dux-Soup vs Octopus CRM

from $9.99 per month (Starter)

Two veteran tools that run on your own machine, and the honest comparison is between Octopus Unlimited at $39.99 and STACKED local at $55. Octopus is simpler and cheaper with a funnel builder but no inbox and only Zapier plus HubSpot for integration. Dux-Soup adds a central inbox, a lead dashboard, six native CRM connectors, and an upgrade path to cloud execution. Take Octopus for the cheapest possible working setup; take Dux-Soup if you want somewhere to grow into.

Full Dux-Soup vs Octopus CRM comparison

Dux-Soup vs PhantomBuster

from $69 per month (Start), or $56 per month billed annually

Different jobs that get confused constantly. PhantomBuster is a cloud extraction platform with excellent data plumbing and indifferent sending; Dux-Soup is an outreach tool with a proper inbox, campaigns, and CRM sync but no scraping pipeline or non-LinkedIn sources. Many teams run both: PhantomBuster to build and enrich the list, Dux-Soup to work it. If you must pick one, pick by whether your bottleneck is data or conversations.

Full Dux-Soup vs PhantomBuster comparison

Dux-Soup vs Kanbox

from $20 per month (Starter), or $12 per month billed annually

Both are extension-based tools with a pipeline view, but Kanbox is French with EU data residency, a Kanban CRM front end, and an entry price of $20, while Dux-Soup is Dutch-operated with a deeper native CRM connector list and a genuine cloud upgrade path. Choose Kanbox for EU residency and the visual pipeline; choose Dux-Soup for CRM integration depth and the ability to move to always-on execution later.

Full Dux-Soup vs Kanbox comparison

Dux-Soup vs Linked Helper

from $15/mo (Standard, local storage, monthly billing)

The closest philosophical relative: both are veteran, technically-minded tools that run outside the cloud. Linked Helper is a desktop application with its own controlled browser, deeper automation, and a built-in CRM, at roughly $15 to $45 a month, but it demands more setup and lives on your machine. Dux-Soup is easier to run, better integrated with mainstream CRMs, and offers a cloud edition Linked Helper does not. Pick Linked Helper for maximum capability per dollar if you enjoy configuration; pick Dux-Soup for integrations and the cloud path.

Full Dux-Soup vs Linked Helper comparison

Dux-Soup vs Meet Alfred

from $29/user/mo (Basic, billed annually)

Meet Alfred is a cloud multichannel tool that adds email and Twitter steps to LinkedIn sequences and prices with team plans in mind. Dux-Soup is LinkedIn-only but has the better CRM connector list and a much longer track record. Take Meet Alfred if multichannel sequencing in one tool is the requirement; take Dux-Soup if LinkedIn is the channel and vendor longevity plus native CRM sync is what you are optimizing for.

Full Dux-Soup stack

Implementation & onboarding

Setup time: Twenty minutes for STACKED local: install the desktop app, open LinkedIn, run a search, scan the results, and start a campaign. The cloud edition adds an account provisioning step handled by the vendor and take a day or so to be fully live.
Learning curve: Moderate, and mostly caused by the edition structure rather than the software. Understanding whether you need Local or Cloud, on fixed or flexible seats, takes longer than learning to build a campaign. The campaign builder itself is conventional and the documentation is mature.
Onboarding: Self-serve on every edition with a 14-day no-credit-card trial. Agency customers get help with account provisioning. There is a large accumulated library of documentation and third-party tutorials because the tool is a decade old.
Migration notes: Lists import by CSV and native CRM connectors mean most teams sync contacts from day one rather than migrating later. On the way out, CSV export covers prospect data, the API and CRM sync cover conversation outcomes, and messages already sent remain in LinkedIn's own inbox. The local edition carries the least exit risk of anything in this category, because the automation ran on your own machine and the record of what it did lives in LinkedIn and in your CRM rather than only inside vendor infrastructure. The cloud edition concentrates more state at the vendor, so wire the CRM sync up on day one if you buy Cloud.

Platform, API & security

Platforms: Desktop app for Mac and Windows (STACKED local)Managed cloud execution (Cloud editions)Web dashboard for campaigns, inbox, and reporting
API: A documented API is offered alongside native CRM connectors, Zapier, and Make, giving several independent paths for getting data out.
Compliance: GDPR (operated by a Dutch entity subject to EU data protection law)
Data residency: Operated by Supertec BV, a Netherlands entity. Customer-selectable regions are not advertised.
SSO: Not advertised on published tiers.
Security notes: The local edition has a real security advantage: automation runs on your own machine and connection rather than on vendor infrastructure. The cloud edition necessarily reverses that, since the vendor must hold a session to run the account for you, and Dux-Soup does not lead with a per-account dedicated country-matched IP claim in the way Expandi and SalesRobot do. If you are buying Cloud specifically for safety reasons, ask directly how the IP is assigned per account before committing.

Support & resources

Channels: Email supportIn-app helpPriority handling for agency and team customers
Documentation: Ten years of accumulated documentation, setup guides, integration walkthroughs, and a long-running blog covering LinkedIn limits and outreach tactics.
Community: Large informal community, a substantial body of third-party tutorials, and an active partner and consultant ecosystem built around the tool.

Frequently asked questions

13 questions

What is Dux-Soup?

Dux-Soup is a LinkedIn automation tool that has been running since 2015 and now sells its product as STACKED, powered by Dux-Soup. It comes in two editions: STACKED local at $55 per seat a month, a Mac and Windows desktop app with unlimited drip campaigns, a lead dashboard, and native CRM integrations; and STACKED cloud at $99, which runs the same automation on managed always-on infrastructure instead of on your machine.

How much does Dux-Soup really cost?

STACKED local is $55 per seat a month, or $41.25 billed annually, and STACKED cloud is $99, or $74.17 billed annually. The old $14.99 Pro edition is no longer sold. Teams get 10 percent off per 10 seats, up to 50 percent, and agencies are billed per active client account at a rate Dux-Soup does not publish.

Can Dux-Soup get my LinkedIn account restricted?

Yes. Automating LinkedIn violates LinkedIn's user agreement whichever tool you use, and accounts are warned, restricted, and permanently banned regularly. Dux-Soup advertises five built-in safety controls, including rate throttling, randomized delays, working-hours scheduling, and daily ceilings, on both editions, and the local edition acts from your own machine and connection, which removes the foreign-datacentre-login signal. That makes it one of the lower-risk architectures here, but the limits are still yours to set sensibly. Stay well inside LinkedIn's roughly 100 invitations per week allowance.

Does Dux-Soup work when my computer is off?

Only on the cloud edition. STACKED local is a desktop app that runs on your own machine, so it stops when the machine is off or asleep. STACKED cloud at $99 per month moves execution onto managed infrastructure with vendor monitoring so campaigns run overnight and across time zones. This upgrade path within one vendor is Dux-Soup's most distinctive structural advantage.

Do I need LinkedIn Sales Navigator?

No. Dux-Soup scans ordinary LinkedIn search results and accepts CSV imports, so a free or Premium LinkedIn account is a genuinely workable setup. That matters for total cost: many cloud competitors effectively assume a $99 per month Sales Navigator seat on top of their own price, whereas a complete Dux-Soup setup can be $55 all in.

Which CRMs does Dux-Soup integrate with?

Native connectors cover HubSpot, Salesforce, Pipedrive, Freshsales, SharpSpring, and HighLevel, with Slack and Microsoft Teams for notifications and Zapier, Make, and an API for everything else. Freshsales, SharpSpring, and HighLevel in particular are ignored by most competitors, so if your business runs on one of them Dux-Soup may be the only tool here that connects without a bridge.

What does Dux-Soup cost for a five-account agency?

STACKED agency is billed per client account actively running, with managed cloud infrastructure per account and a single dashboard across unlimited client accounts. Dux-Soup no longer publishes the rate, so ask for a quote and compare it with Aimfox's published twenty-seat plan before committing.

What happens to my campaign data if Dux-Soup shuts down or LinkedIn blocks it?

You are better protected than with most tools here, especially on the local edition. Prospect data exports as CSV, native CRM connectors mean contacts and outcomes usually already live in HubSpot or Pipedrive rather than only in Dux-Soup, and every message sent stays in LinkedIn's own inbox. The cloud edition concentrates more state at the vendor, so if you buy Cloud, configure CRM sync in your first week rather than treating it as a later project.

Is Dux-Soup still actively maintained?

Yes. It is one of the few genuinely long-lived vendors in this category: founded in 2015, ten years of operation marked in 2025, over 300,000 claimed users, current pricing and documentation, and an active integration roadmap that recently added AI message generation through Claude, ChatGPT, and Gemini. Feature velocity is slower than newer entrants, but abandonment is not a concern here in the way it is with several competitors.

Who owns Dux-Soup?

Dux-Soup is operated by Supertec BV, a Netherlands entity, and was founded in 2015 by Will van der Sanden, who came from a software development and enterprise data integration background. There is no disclosed institutional funding; the company appears to have grown on revenue. Being an EU-registered company also means it operates under GDPR, which some buyers will treat as a meaningful advantage over vendors registered in free zones with no published leadership.

What should I pair Dux-Soup with?

What do I pair with Dux-Soup for Cold Email Outreach?

Smartlead. Dux-Soup sends buyers elsewhere for multichannel email in the same sequence. Smartlead adds true white-label portal.

Is Dux-Soup enough on its own?

For LinkedIn, yes. Dux-Soup does not cover B2B data providers, sales CRM and scheduling & booking, and its own profile says so; Lusha, Zoho CRM and zcal are the tools that fill those gaps.

Editorial verdict

Dux-Soup is the safe, unglamorous choice, and there is a real argument for making it. It has survived a decade of LinkedIn enforcement, it has the best native CRM connector list in the category by some distance, its local edition runs from your own machine rather than a vendor datacentre, and it needs no Sales Navigator seat, so a complete working setup is $55 a month. Above all, it lets you start on your own machine and move to managed always-on cloud execution without changing tools. What you give up is modernity and scale economics: there is no email channel, no event extraction, no voice messages, the interface shows its age, and Cloud at $99 a seat is expensive next to Aimfox or HeyReach. Buy STACKED local at $55 if LinkedIn is your channel, your CRM is on the native list, and you value a vendor that will still exist in three years.
