wacrm vs WATI: an honest open-source alternative comparison

WATI is one of the cheapest ways to get onto the official WhatsApp Business API — $19/month gets you a team inbox and broadcasts. wacrm is a free, MIT-licensed, self-hosted WhatsApp CRM with no per-seat cost.

At three users, WATI is genuinely inexpensive and this is a closer contest than you might expect. The gap opens as the team grows. Here is the honest version.

Disclosure: wacrm publishes this comparison. Pricing below comes from WATI's own pricing page and was checked in August 2026 — plans change, so verify before you commit.

The short version

• Choose WATI if you are a small team that wants to be live this week with no infrastructure to run, and you value a mature onboarding path onto the WhatsApp Business API.
• Choose wacrm if your team will grow past a handful of agents, you want sales pipelines rather than just an inbox, or you want to own the data.

Meta's messaging fees are billed by Meta and are the same either way.

The seat maths

This is where the two diverge sharply, and it is worth being precise rather than hand-wavy about it.

• Growth ($19/mo) includes 3 users and does not allow additional users at all. Your fourth agent forces an upgrade.
• Pro ($49/mo) includes 5 users, then $24 per extra user per month.
• Business ($99/mo) includes 5 users, then $69 per extra user per month.

A ten-person support team on Pro is $49 + (5 × $24) = $169/month, or about $2,028/year. On Business it is $99 + (5 × $69) = $444/month. Note the counterintuitive shape: the higher tier charges nearly three times as much per additional seat, so growing into Business for its features gets expensive fast.

wacrm has no seat concept. Ten agents cost the same as one: your hosting bill and Meta's messaging.

At three users, though, WATI is $228/year all-in and requires zero operational work. That is a real offer and worth taking seriously if your team is that size and likely to stay there.

Automation and API limits

WATI's advanced automation is gated to Pro, and its API is metered — 10,000 calls a month on Growth, with no webhooks at all on that tier. For an integration that reacts to inbound messages, no webhooks is a hard blocker, not an inconvenience.

wacrm's public API and outbound webhooks are included and unmetered, because the app runs on your own server; the only ceiling is your hosting. Its automations and branching Flows are not gated behind a tier either.

Feature by feature

Shared inbox. Both do it well. WATI's is mature and well-supported; wacrm's covers assignment, internal notes, tags, templates, and real-time collision handling.

Broadcasts. WATI Growth caps at 15,000 broadcasts/month, unlimited on Pro and above. wacrm's broadcasts have no software-imposed cap — you are limited by Meta's messaging rates and your own budget.

Sales pipelines. wacrm ships kanban pipelines with deal values and stage totals. WATI is an inbox-and-campaigns tool rather than a deal CRM, so if you are tracking opportunities you would pair it with a separate CRM.

AI. WATI's Astra AI Agents are an add-on on Pro and included on Business, with metered AI credits. wacrm's AI assistant is bring-your-own-key: you paste an OpenAI or Anthropic key and pay the provider directly, with no markup and no per-seat AI fee.

Where WATI is the better choice

• You are three people and want to launch immediately. $19/month and no server to run is hard to argue with. Self-hosting only pays off past a certain size.
• You want guided WhatsApp Business API onboarding. WATI does the Meta approval dance with you. With wacrm you follow the WhatsApp setup guide yourself.
• You need several WhatsApp numbers under one roof. WATI Business supports multiple numbers; wacrm is one number per deployment, so you would run an instance per number.
• You want 24×7 support with an SLA. wacrm has GitHub issues.

Migrating from WATI

Export contacts as CSV from WATI and import them into wacrm. Chat history and chatbot definitions do not transfer — carry the contact list, rebuild your automations, start fresh on threads. The WhatsApp number is registered to your Meta Business account, so it moves with you rather than being locked to WATI.

The honest bottom line

WATI at $19/month for three users is the best-value entry point in this comparison, and pretending otherwise would be silly. The reason to leave is growth: the fourth agent forces a plan change, and the eleventh agent costs $24–69/month on top of a plan you are already paying for.

wacrm's cost curve is flat. Ten agents, fifty agents, unlimited broadcasts, an unmetered API — the bill does not move, because there is no vendor in the middle metering it.
