The short answer
Editorial assessmentHiver compared with Plain
Plain is built for engineering-led B2B companies whose customers live in shared Slack, Teams, or Discord channels, and it expects you to treat support as an API-driven system. Hiver is built for non-technical teams in finance, IT, operations, and support who live in email and want as little change as possible. They barely overlap. Choose Plain if your customers are developers and your support team can write code; choose Hiver if the person who owns support would describe a GraphQL API as somebody else's problem.
Choose Hiver if
Small and mid-sized teams already standardised on Google Workspace or Microsoft 365 whose support is email-led and whose biggest problem is coordination rather than volume. It suits support, finance, IT, and operations teams of roughly three to thirty people who need assignment, SLAs, and real reporting without asking anyone to abandon their inbox.
Choose Plain if
B2B software companies, especially developer-tools and infrastructure startups, whose customers are technical, whose support arrives in shared Slack, Teams, or Discord channels, and who have engineering capacity to use an API-first platform properly.
Side by side
13 attributes| Attribute | Hiver | Plain |
|---|---|---|
| Category | Support | Support |
| Starting price | $25 per user per month (Growth, billed annually; $35 monthly) (free plan available) | $45 per user per month billed annually (Foundation, $55 monthly) (7 days trial) |
| Pricing model | Per-user subscription across three paid tiers, billed monthly or annually, with AI bundled into the seat price from Growth upward rather than metered per resolution. Seats are sold in fixed increments rather than one at a time. | Per-seat subscription in three tiers, each with a seat band and a monthly credit allowance that both AI agents draw on. Ari, the customer-facing agent, costs 100 credits per resolution; Sidekick, the internal copilot, costs 15 to 300 or more credits depending on the effort a task takes. Viewer seats are unlimited and free on every plan. Billed annually or monthly, with the annual rate roughly 20% lower and double the included credits. |
| Free plan | None currently advertised on Hiver's pricing page. Several third-party pricing trackers still list a free tier, which appears to be stale; treat the 7-day trial as the evaluation path and confirm at signup. | No |

| Setup time | Under an hour for a working setup. Install the extension across the team, connect the shared mailboxes, and the sidebar appears in everyone's Gmail. This is the fastest meaningful deployment in the category precisely because there is no new interface to roll out. | A working workspace with Slack and email connected in an afternoon. Getting real value (workflows routing to Linear, customer cards populated from your own API, Ari trained on your documentation, SLAs configured) is more like two to four weeks with engineering involvement. |
| Learning curve | Close to zero for agents, which is the entire point. The only new concepts are assignment, status, and internal notes, all of which sit visibly in an interface people already know. The administrator has automation rules, SLA policies, and mailbox configuration to learn, which is an afternoon rather than a project. | Low for agents, moderate to high for the person configuring it. The API-first design means the best implementations involve writing code, and teams that treat Plain as a point-and-click help desk will under-use it. The 7-day trial is short for a proper technical evaluation, so plan the pilot before starting the clock. |

Strengths and limitations
Hiver
Strengths
- Adoption is close to free. Agents keep working in Gmail or Outlook, which sidesteps the single biggest failure mode of help desk rollouts.
- AI is bundled into the seat price from Growth upward with no per-resolution meter, so the monthly bill is genuinely fixed while competitors scale with volume.
- Because Hiver operates on your existing mailboxes, evaluating it carries almost no switching risk: if you stop paying, your mail is exactly where it always was.
- Analytics are strong for an inbox product: response time, resolution time, workload distribution, SLA compliance, and CSAT all reported properly.
Limitations
- The seat increment structure is user-hostile. Two, then five, then multiples of five means teams routinely pay for one to four seats they do not use.
- No light agent or read-only seat, so every engineer, contractor, or stakeholder who needs visibility costs a full licence.
- It is an inbox, not a ticketing engine. There are no custom ticket fields, conditional forms, skills-based routing, or multi-brand help centers, and a growing support operation will hit that ceiling.
- The knowledge base is functional but noticeably weaker than Zendesk's or Freshdesk's on theming, multi-brand support, and SEO control.
Plain
Strengths
- Slack, Teams, and Discord are treated as genuine support channels with assignment, status, and SLA tracking, which no general-purpose help desk in this set does properly.
- Both AI agents run from one credit pool rather than a separate per-resolution invoice line, so AI spend is capped by the allowance you bought instead of accruing unpredictably.
- Unlimited free viewer seats let an entire engineering organisation follow customer threads without a per-seat charge, matching how B2B software companies actually work.
- The GraphQL API, MCP server, and bring-your-own-agent model make Plain programmable in a way that lets a team build its own support surface rather than living inside the vendor's UI.
Limitations
- Ari stopped being free. The October 2026 pricing page meters a customer-facing resolution at 100 credits, so Foundation's 1,000 monthly credits cover about ten of them, and the pricing page publishes no rate for buying more.
- Sidekick credits are metered by effort rather than volume, which makes the variable portion of the bill genuinely hard to forecast month to month.
- No voice or telephony of any kind, and no realistic path to phone support.
- Wrong shape for consumer and ecommerce support: no order-management story, no Shopify depth, and a channel mix aimed at business customers.
Pricing compared
Hiver
Per-user subscription across three paid tiers, billed monthly or annually, with AI bundled into the seat price from Growth upward rather than metered per resolution. Seats are sold in fixed increments rather than one at a time.
- Growth$25
- Pro$55
- Elite$85
Hiver's value case is adoption and predictability rather than raw capability. You are paying so that nobody has to learn a new tool, and so that your support bill stays the same number every month regardless of volume. Both are worth real money. At $25 a seat with AI included, a five-seat team pays $125 a month for coordination, automation, analytics, and AI drafting, which is less than a single Zendesk Suite Professional seat plus Copilot. The weaknesses are structural: the seat increments overcharge teams whose headcount is not a multiple of five, there is no light agent option, API access costs $55 a seat, and the knowledge base and routing are noticeably thinner than a real help desk. If your support is email-led and your problem is coordination, this is excellent value. If your problem is volume, Hiver is the wrong shape and its bundled AI will not save you.
Plain
Per-seat subscription in three tiers, each with a seat band and a monthly credit allowance that both AI agents draw on. Ari, the customer-facing agent, costs 100 credits per resolution; Sidekick, the internal copilot, costs 15 to 300 or more credits depending on the effort a task takes. Viewer seats are unlimited and free on every plan. Billed annually or monthly, with the annual rate roughly 20% lower and double the included credits.
- Foundation$45
- Horizon$99
- FrontierCustom
Plain repriced in 2026 and the shape of the deal changed with it. Where Foundation was $35 a month for a seat with the AI agent thrown in, it is now $45 per seat per month billed annually with AI metered out of a 1,000-credit allowance, and Horizon doubles that to $99 with a three-seat minimum. Against Help Scout's $25 Standard seat or Chatwoot's $19, Plain is now clearly the premium option on list price, and the credit meter means a successful deflection programme costs more rather than less. What still justifies it for the right buyer: unlimited free viewer seats, so a fifteen-engineer company can pay for five and let everyone read; Slack, Teams and Discord as first-class channels rather than integrations; and a GraphQL API deep enough to build your own support surface. For a five-person developer-tools company whose customers file issues in Slack, that combination has no real substitute and the startup programme's 50% takes the sting out. For a non-technical team doing email support, Plain is now expensive in both dimensions, seat and usage, and the alternatives are better value.
Editorial verdict on each
Hiver
Ease of UseHiver solves a real and underrated problem: help desks fail not because they lack features but because agents quietly keep working in Gmail. By putting assignment, SLAs, analytics, and AI inside the mail client people already use, Hiver gets adoption almost for free, and it is one of very few vendors in this category that has refused to attach a per-resolution meter to its AI. A five-seat team pays $125 a month at any volume, which is a genuinely differentiated offer in 2026. The reservations are concrete rather than philosophical: the two-then-five-then-fives seat structure overcharges most teams, there is no light agent seat, API access costs $55 per user, and the knowledge base and routing are thinner than a real ticketing platform. Buy Hiver if your support is email-led, your team is on Google Workspace or Microsoft 365, and coordination rather than volume is your problem. If you need deflection at scale or a configurable ticket model, buy something else.

MomentumPlain is the sharpest product in this category for a specific and growing shape of company: B2B software businesses whose customers are engineers, whose support lands in Slack, and whose escalations end in Linear. The channel model is right, the free viewer seats reflect how those teams actually operate, the GraphQL API and MCP server make it programmable rather than merely configurable, and and one credit pool is simpler to govern than a separate AI invoice. The reservations grew in 2026: the entry seat is $45 and Horizon is $99 with a three-seat minimum, Ari went from included to 100 credits a resolution, credits are hard to forecast because Sidekick meters effort rather than volume, there is no voice channel, and there is no free plan. Buy Plain if your customers write to you in a shared Slack channel. If they do not, almost everything here will serve you better and cost less.

The best in Customer Support Platforms
27 trackedCustomer support platforms consolidate email, live chat, and help-center content into shared inboxes and ticket queues, so a small team can answer customers without dropping conversations.
The shared inbox that never makes customers feel like ticket numbers, matured into the small-business support standard.
A complete help desk with unlimited agents for nothing, permanently, funded by services rather than seats.
A $15M Series A in February 2025 and a customer list spanning Vercel, Cursor, and Raycast mark Plain as the breakout support desk for developer tools.
Fin answered the pricing question AI support created: 99 cents per resolved conversation, with humans only where the agent fails.
Hiver deploys in under an hour with no new interface to roll out, and agents work inside Gmail so the learning curve is close to zero.
