Nudgify
Six kinds of nudge, unlimited websites, and a free tier that never expires
Nudgify is a social proof and conversion nudge app that displays real-time popups on a website across six categories: live visitor counts and sales notifications, low-stock and selling-fast FOMO alerts, customer review nudges, time-based urgency prompts, friction-reducing messages such as free-delivery thresholds, and fully custom nudges; it is metered by monthly impressions rather than by site, supports unlimited websites on every plan including the free one, and starts at $9 a month with a permanent free tier at 1,000 impressions.
Overview
Nudgify sits in the third job of this category, live activity notifications and conversion nudges, and it distinguishes itself from the rest by treating the popup as a general-purpose messaging surface rather than only as a purchase ticker. The nudge library spans six categories: social proof showing live visitor counts, sales, and recent signups; FOMO showing low stock and selling-fast alerts; reviews displaying customer ratings pulled from Trustpilot, Google, or Capterra; urgency showing time-limited order reminders; friction reduction showing free-delivery thresholds and available discounts; and custom nudges you write yourself.
That friction-reduction category deserves attention because it is the least cynical thing in this sub-category. A popup telling a shopper that they are eleven dollars away from free delivery is not manufactured urgency; it is useful information delivered at the moment it changes a decision. Tools that only do purchase tickers cannot do this, and it is the strongest argument for Nudgify over a pure notification app.
The metering model is the other real differentiator. Where TrustPulse charges by monthly unique visitors and caps the number of sites at one, two, five, or ten by tier, Nudgify charges by impressions and allows unlimited websites, unlimited sessions, and unlimited nudges on every plan including free. Lite is $9 a month for 10,000 impressions, Plus is $29 for 90,000, Genius is $49 for 300,000, Agency is $89 for a million, and Enterprise is $189 for three million. Lifetime deals are published at roughly a hundred times the monthly price. A permanent free plan gives 1,000 impressions a month with limited nudge styling and one review source, and a 7-day trial with no card required opens up the Lite feature set.
The honest caveat is the same one that hangs over every product in this sub-category. Live activity popups worked well when they were novel and are contested now. Nudgify's spread of nudge types partially insulates it, because a low-stock alert or a free-delivery threshold reads as information rather than as manufactured herd pressure, but the sales-notification format itself has been devalued by overuse and by tools that fabricate events. The vendor cites more than 3,100 brands across 138 countries in 30 languages, which is real traction, but no vendor's conversion claim in this category should be accepted without testing it on your own traffic.
Best for
Ecommerce operators who want more than a purchase ticker, particularly stores that would benefit from low-stock alerts and free-delivery threshold prompts, and agencies managing many client sites who need unlimited websites on a single subscription rather than a per-site allowance.
Not the right fit for
- Businesses that need durable social proof; nudges vanish the moment you stop paying, so testimonials and reviews from Senja, Famewall, or Judge.me should be funded first.
- Brands where a floating popup cheapens the presentation, including luxury, professional services, healthcare, and most enterprise B2B sites.
- High-traffic stores on the cheap tiers, because 10,000 impressions on the $9 Lite plan is exhausted quickly once nudges are showing on every page.
- Anyone looking to manufacture urgency dishonestly; a low-stock alert that is not true is a consumer protection problem in several jurisdictions, not a growth tactic.
- Buyers needing SSO, compliance certifications, or a procurement process; this is a small vendor selling a $9 conversion utility.
How it works
- 1
You add Nudgify to your site through a platform integration or Google Tag Manager. Shopify, WooCommerce, BigCommerce, Magento, PrestaShop, WordPress, Wix, and Blogger are all supported natively, and anything else takes a script tag.
- 2
You build nudges in a drag-and-drop workspace. Each nudge draws on live data: order events for sales notifications, session data for visitor counts, inventory levels for low-stock alerts, cart values for free-delivery thresholds, and connected review platforms for rating nudges. Reviews can be pulled from Trustpilot, Google Reviews, and Capterra, with review source counts tiered by plan from three on Lite up to 300 on Agency.
- 3
You configure where and when each nudge appears. Because sessions and nudge count are unlimited on every plan, the only thing you are spending is impressions, which changes the mental model: rather than rationing sites or campaigns, you ration how often a nudge is actually rendered.
- 4
The nudges display in 30 languages with styling controls that go beyond the vendor default on paid plans. Integrations with Mailchimp, ActiveCampaign, Stripe, PayPal, and Zapier feed additional event sources, and the free plan keeps integrations open while limiting nudge styling and types, which is a more useful free-plan structure than cutting off connectivity.
Feature breakdown
24 features in 4 modulesThe nudge library
Six categories, which is the widest spread in this sub-category and the main reason to choose it.- Social proof nudges
- Live visitor counts, sales popups, and recent signups, drawn from real session and order data. This is the classic format every competitor offers.
- FOMO nudges
- Low stock and selling fast alerts driven by actual inventory levels. Genuinely useful when true, and a legal problem when not, so wire them to real stock data and leave them there.
- Review nudges
- Customer ratings displayed as nudges, pulled from Trustpilot, Google Reviews, and Capterra. Review source allowances scale by plan: three on Lite, 30 on Plus, 100 on Genius, 300 on Agency.
- Urgency nudges
- Time-limited order reminders such as a cut-off for next-day dispatch, which is information rather than pressure when the cut-off is real.
- Friction reduction nudges
- Free-delivery thresholds and available discount prompts. This is the least cynical format in the category, because it tells a shopper something that genuinely changes their decision, and pure notification tools cannot do it.
- Custom nudges
- Write your own message for any purpose, which turns the tool into a general on-site messaging surface rather than only a proof ticker.
- Nudge library and templates
- A prebuilt catalogue of nudge configurations so you are not starting from an empty canvas on every campaign.
Metering and allowances
Impression-based rather than site-based, which is the structural difference from TrustPulse.- Unlimited websites on every plan
- Including the free plan. TrustPulse allows one site on Basic and ten on its top tier, so for an agency the difference in structure is worth more than the difference in headline price.
- Unlimited sessions and nudges
- Session count and nudge count are never the meter, so you are only ever managing how often nudges render.
- Impression metering
- 1,000 impressions a month free, 10,000 on Lite, 90,000 on Plus, 300,000 on Genius, one million on Agency, three million on Enterprise.
- Permanent free plan
- 1,000 impressions a month with one review source and limited nudge styling and types, but with integrations left open, which makes it a genuine evaluation path rather than a demo.
- Lifetime pricing
- One-time purchases published at roughly a hundred times the monthly price, from $800 for Lite to $8,900 for Agency. Worth calculating only if you are confident the category still works for you in five years.
- Thirty languages
- Nudges render in 30 languages on every plan, so a multi-market store does not need a separate configuration per locale.
Building and styling
Drag-and-drop configuration with styling gated on the free tier.- Drag-and-drop workspace
- Nudges are assembled visually rather than configured through forms, which suits marketers building several variants.
- Nudge styling controls
- Appearance customization on paid plans; the free tier restricts both styling and which nudge types are available, which is where the upgrade pressure sits.
- Live data communication
- Nudges reflect current state rather than a cached snapshot, which is what makes stock levels and cart thresholds usable.
- Timing and display rules
- Control over when and how often a nudge renders, which is also how you manage your impression budget.
- Widget page-speed cost
- Nudgify is third-party JavaScript that communicates live data, so it keeps working after page load rather than rendering once. Stock and cart-value nudges are the most expensive because they need current state; a static custom nudge is cheap.
Integrations
Broad platform coverage with integrations open even on the free plan.- Ecommerce platforms
- Shopify, WooCommerce, BigCommerce, Magento, and PrestaShop native integrations for order, session, and inventory data.
- CMS and site builders
- WordPress, Wix, and Blogger, plus Google Tag Manager for anything else.
- Review platform connections
- Trustpilot, Google Reviews, and Capterra feeding the review nudge type, with source counts tiered by plan.
- Marketing tools
- Mailchimp, ActiveCampaign, and Zapier for event sources outside the native list.
- Payment systems
- Stripe and PayPal connections so purchase events can drive nudges on non-standard checkout flows.
- Integrations open on the free plan
- The free tier limits styling and nudge types but keeps connectivity, which is a better structure than free plans that cut you off from your own data.
Use cases
4 documentedStore raising average order value with delivery thresholds
Free delivery starts at a certain cart value and shoppers only discover it at checkout, by which point they have stopped shopping.
A friction reduction nudge tells them how far they are from the threshold while they are still browsing. This is information rather than pressure, and it is the nudge type most likely to survive a skeptical audience.
Agency running nudges across twenty client sites
Every notification tool charges per site, and twenty small client sites would mean either twenty subscriptions or a top-tier plan.
Unlimited websites on every Nudgify plan means the Agency tier at $89 covers all twenty against a shared million-impression pool, which is a fundamentally better structure than TrustPulse's ten-site ceiling.
Store with real inventory scarcity
Popular lines genuinely sell out, shoppers do not know it, and they return two days later to find the item gone.
Low-stock FOMO nudges wired to actual inventory levels tell them the truth at the right moment. Wired to real data this converts honestly; invented, it is a consumer protection problem.
Small site testing the category for free
The owner wants to know whether nudges help before spending anything, and every competitor requires payment or a card up front.
The permanent free plan gives 1,000 impressions a month with integrations open, enough to run a real if small test, and a 7-day no-card trial opens the Lite feature set on top.
Pricing
from $0 (free, 1,000 impressions), then $9 per month (Lite)Freemium subscription metered by monthly nudge impressions, with unlimited websites, sessions, and nudges on every plan. Monthly, annual, and one-time lifetime pricing are all published.
| Plan | Price | Includes |
|---|---|---|
| Free | $0 per month |
Permanent rather than a trial, and unusually it keeps integrations open rather than cutting off your data. |
| Lite | $9 per month, $90 per year, or $800 lifetime |
|
| Plus | $29 per month, $290 per year, or $2,900 lifetime |
The plan most real ecommerce sites land on once nudges run on more than one page. |
| Genius | $49 per month, $490 per year, or $4,900 lifetime |
|
| Agency | $89 per month, $890 per year, or $8,900 lifetime |
Unlimited websites plus a million shared impressions is the best agency structure in this sub-category. |
| Enterprise | $189 per month |
|
Billing notes
- Annual billing is priced at ten months, so a year costs the same as ten months of monthly billing.
- Lifetime purchases are published at roughly a hundred times the monthly price, from $800 on Lite to $8,900 on Agency, which pays back in a bit over eight years of annual billing.
- The meter is impressions, not visitors or sites, so a nudge shown on every page burns budget several times faster than one shown at checkout only.
- Unlimited websites on every plan including free makes agency use viable on a single subscription, which no other tool in this sub-category matches.
- The 7-day trial requires no credit card, and the free plan is permanent, so evaluation costs nothing.
Value assessment: Nudgify is priced sensibly and structured better than its direct competitors. Unlimited websites on every plan including free is a genuinely different model from TrustPulse's one-to-ten site ceilings, and it makes the $89 Agency tier the best multi-client deal in this sub-category by a wide margin. The six-category nudge library also gives you more per dollar than a pure activity ticker, and the friction-reduction nudges in particular do something no competitor here offers. Against that, the impression meter is easy to burn: 10,000 impressions on the $9 Lite plan disappears in days on any site with traffic, so most real stores are on the $29 Plus tier and should budget accordingly. TrustPulse is cheaper at the very bottom, at $5 for a single site. The larger question is unchanged: this is a rented tactic, not an owned asset, and nothing here compounds. Use the free plan to test, move to Plus if the numbers justify it, and never let this line item outrank a review or testimonial tool in your budget.
Strengths & limitations
Strengths
- Six nudge categories rather than one, including friction reduction and low-stock alerts that carry real information rather than manufactured urgency.
- Unlimited websites, sessions, and nudges on every plan including free, which is a structurally better model for agencies than any per-site competitor.
- A permanent free plan at 1,000 impressions that keeps integrations open rather than cutting you off from your own data.
- Free-delivery threshold nudges are the most defensible format in this whole sub-category, because they tell shoppers something genuinely useful at the moment it matters.
- Review nudges pull ratings from Trustpilot, Google Reviews, and Capterra, so an existing review investment is reused rather than duplicated.
- Thirty languages on every plan, so multi-market stores do not need parallel configurations.
- Broad platform coverage including Shopify, WooCommerce, BigCommerce, Magento, PrestaShop, WordPress, Wix, and Google Tag Manager.
- A 7-day trial with no card required on top of a permanent free tier, so evaluation costs nothing at all.
Limitations
- The impression meter burns fast: 10,000 a month on the $9 plan is exhausted quickly if nudges run site-wide, pushing most real stores to $29.
- Nudges are rented, not owned. Cancel and every trace of social proof disappears the same day, unlike testimonials and reviews.
- The category itself is contested; sales-notification popups have been devalued by overuse and by tools that fabricate events, regardless of whether yours are real.
- Low-stock and urgency nudges are a compliance risk if they are not wired to genuine data, and several jurisdictions treat false scarcity claims as a consumer protection matter.
- Free-plan styling and nudge type limits are the real gate, so the free tier is an evaluation path rather than a lasting option for a business site.
- No SEO value at all: nudges are client-side rendered and emit no structured data, so they contribute nothing to search visibility.
- No SSO, no published compliance certifications, and no enterprise procurement path.
- The vendor is small and does not publish founder, headcount, or headquarters detail, which is a modest transparency gap compared with the rest of this category.
Head-to-head comparisons
5 alternativesNudgify vs TrustPulse
from $5 per month billed annually (Basic), or $9 per month at the standard rateThe head-to-head in this sub-category, and it turns on structure rather than price. TrustPulse is cheaper at the bottom, $5 a month on annual billing, but meters by unique visitors and caps you at one to ten sites by tier. Nudgify starts at $9 for 10,000 impressions with unlimited websites on every plan, has a permanent free tier, and offers six nudge categories against TrustPulse's four formats. Single-site owners will often find TrustPulse cheaper; agencies and anyone wanting stock or delivery-threshold nudges should take Nudgify.
Full Nudgify vs TrustPulse comparisonNudgify vs ProveSource
from $0 (free under 1,000 monthly unique visitors), then $24 per month billed yearly (Starter)ProveSource is the established specialist in live activity notifications with deep ecommerce integrations and a mature notification set, priced above Nudgify. Nudgify covers a wider range of nudge types, including friction reduction and urgency formats ProveSource does not emphasize, and allows unlimited websites. If pure activity notifications are the requirement, ProveSource is the deeper tool; if you want a general on-site nudge surface, Nudgify is the better shape.
Full Nudgify vs ProveSource comparisonNudgify vs Fomo
from $25 per month (Starter)Fomo is the oldest name in live activity notifications, metered by notification volume from around $25 a month. Nudgify starts at $9, meters impressions, and adds low-stock, urgency, review, and friction-reduction nudges beyond the purchase ticker both share. Fomo carries more brand history; Nudgify carries more format variety and a free plan. Neither differentiates enough to matter next to the prior question of whether popups still convert on your traffic.
Full Nudgify vs Fomo comparisonNudgify vs Judge.me
from $0 (Forever Free), then $15 per month (Awesome)Complements rather than competitors, and the priority order is clear. Judge.me collects unlimited product reviews for $15 a month flat with free rich snippets, building an asset that keeps converting and feeding search for years. Nudgify rents attention with popups from $9 that vanish when you cancel. Nudgify can even display a store's reviews as a nudge type. Collect the reviews first; nudge on top of them second.
Full Nudgify vs Judge.me comparisonNudgify vs Endorsal
from $0 (free), then $29 per month (Starter, billed annually at $351)Endorsal automates testimonial collection and display on your own website, producing durable proof you own and control. Nudgify renders live nudges that leave nothing behind. They cover different halves of social proof, and a site running both would use Endorsal for the testimonial wall and Nudgify for the checkout-page delivery-threshold prompt. If budget forces a choice, the testimonials are the asset.
Full Nudgify vs Endorsal comparisonImplementation & onboarding
- Setup time
- Under half an hour. Install the platform integration or add the script through Google Tag Manager, connect an order or inventory source, build one nudge from the library, and set display rules. The nudge library means the first campaign is configuration rather than design.
- Learning curve
- Low technically and moderate editorially. The drag-and-drop workspace is straightforward. The judgement calls are which nudge types suit your audience, how many impressions to spend where, and whether any given format helps or cheapens the page, all of which take a few weeks of data.
- Onboarding
- Entirely self-serve on every tier with a permanent free plan and a 7-day no-card trial. There is no demo gate and no sales call at any price point including Enterprise at $189.
- Migration notes
- Nothing migrates in or out, because nudges create no durable asset. This is the defining characteristic of the notification job compared with testimonials and reviews: the day you cancel, the social proof stops entirely. Moving to a competitor means swapping one script for another, a ten-minute change. The only thing worth documenting before you leave is your nudge configuration and which placements performed, since that knowledge is the real accumulated value.
Platform, API & security

- Security notes
- Nudgify renders visitor activity including names and approximate locations to other visitors, which is personal data being shown publicly. Confirm your privacy policy covers this. Separately, low-stock and urgency nudges carry a compliance dimension that pure display tools do not: false scarcity claims are treated as a consumer protection issue in several jurisdictions, so wire those nudge types to genuine inventory and deadline data rather than to fixed numbers.

Frequently asked questions
10 questionsWhat is Nudgify?
Nudgify is a social proof and conversion nudge app. It displays real-time popups across six categories: live visitor counts and sales notifications, low-stock and selling-fast alerts, customer review nudges pulled from Trustpilot, Google, and Capterra, time-based urgency prompts, friction-reducing messages such as free-delivery thresholds, and custom nudges you write yourself. It is metered by monthly impressions and allows unlimited websites on every plan.
How much does Nudgify cost?
There is a permanent free plan with 1,000 impressions a month. Lite is $9 for 10,000 impressions, Plus is $29 for 90,000, Genius is $49 for 300,000, Agency is $89 for one million, and Enterprise is $189 for three million. Annual billing costs ten months, and lifetime purchases are published at roughly a hundred times the monthly price. Every plan, including free, allows unlimited websites, sessions, and nudges.
Do live activity popups still convert, or do they read as spam now?
It is a fair question and you should treat it as unresolved. The sales-notification format has been seen by consumers tens of thousands of times, some tools fabricate events, and a meaningful segment now reads the format as a dark pattern. Nudgify is partly insulated because its most useful nudges, low stock and free-delivery thresholds, carry real information rather than herd pressure. Use the free plan to test on your own traffic before committing, and be willing to conclude that the purchase ticker specifically does not work for your audience.
How does Nudgify compare to TrustPulse?
The structural difference matters more than the price. TrustPulse starts at $5 a month on annual billing but meters by unique visitors and allows one site on Basic and ten on its top tier. Nudgify starts at $9 for 10,000 impressions with unlimited websites on every plan including free, and offers six nudge categories against TrustPulse's four formats. Single-site owners will often pay less with TrustPulse; agencies and anyone wanting stock or delivery nudges should take Nudgify.
What happens to my social proof if I stop paying?
It disappears entirely on the day you cancel. Nudges are rendered live from your data and nothing is stored as a durable asset. This is the fundamental difference between the notification job and the testimonial or review jobs, where the collected content stays yours and keeps working indefinitely. It is the clearest reason to fund a review or testimonial tool before a nudge tool.
Does Nudgify help SEO or emit structured data?
No. Nudges are rendered client-side and emit no Review or AggregateRating structured data, so there is no search benefit at all. If SEO is what you want from social proof, you need a review tool: Judge.me emits rich snippets on its free plan, Loox at $14.99, Famewall at $12, Testimonial.to at $50, and Senja at $59.
Are low-stock nudges risky?
Only if they are not true. Wired to real inventory levels they are useful information and among the most defensible formats in this category. Displayed as a fixed message on a product with plenty of stock, they are a false scarcity claim, which several jurisdictions treat as a consumer protection matter rather than a marketing choice. Connect the nudge to your actual inventory data and leave it there.
Will Nudgify slow down my site?
There is a real cost. Nudgify is third-party JavaScript that communicates live data, so unlike a static testimonial embed it keeps working after page load. Stock-level and cart-value nudges are the most expensive because they need current state, while a static custom nudge is cheap. Limit nudges to the pages where they earn their place, which also conserves your impression budget.
Is Nudgify good for an agency?
It is the best structured option in this sub-category for that use. Unlimited websites on every plan means the $89 Agency tier covers any number of client sites against a shared million-impression pool, where TrustPulse caps at ten sites even on its top plan. The constraint is that the impression budget is shared, so a few high-traffic clients can consume it quickly.
Can Nudgify display my existing reviews?
Yes. Review nudges pull ratings from Trustpilot, Google Reviews, and Capterra, with source allowances scaling by plan from one on the free tier to 300 on Agency. This is a sensible way to reuse an existing review investment rather than duplicating it, and it is one of the few nudge formats that draws on an asset you already own rather than manufacturing a new signal.
Editorial verdict
Nudgify is the best-structured product in the notification half of this category, and the reason is not the price but the model. Unlimited websites on every plan including free makes it the only sensible choice for an agency, and the six-category nudge library gives you formats a purchase ticker cannot: low-stock alerts wired to real inventory, free-delivery threshold prompts, and review nudges that reuse ratings you already have. Those friction-reduction nudges are the most defensible thing in this entire sub-category, because they tell a shopper something genuinely useful at the moment it changes their decision. The impression meter burns faster than the $9 headline suggests, so budget for the $29 Plus tier if your site has real traffic. And hold the whole category at arm's length: nudges are rented attention that stops the day you cancel, they contribute nothing to search, and the purchase-notification format specifically has been devalued by years of overuse. Test on the free plan, believe your own numbers, and fund your reviews first.
