Quick answer: Chatwoot merges website chat, WhatsApp and email into one shared inbox, with no per-agent fee. That’s the point: commercial tools in this category charge per team member, so the saving grows with headcount. With one agent it isn’t worth it; from three or four upward, it is. It wants about 4 GB of RAM and, for WhatsApp, you’ll still pay Meta separately for messages.

If you serve customers across three channels and each one lives in its own app, you already know the problem: nobody knows what was answered or who was left hanging. The tools that solve it charge per agent per month, which is exactly the model that explodes as the team grows. Chatwoot is the most established open-source alternative.

What it does

• One inbox for every channel: your website chat, WhatsApp, email, social messages.
• Assignment across the team, with each conversation owned by someone specific so nothing goes unanswered.
• Saved replies for whatever you answer twenty times a day.
• A contact record with the history of previous conversations, which is what stops customers repeating themselves.
• Business hours, with an automatic out-of-hours message.
• No agent limit. Adding the fifth person doesn’t change the bill.

What it actually costs

The licence is €0, but there are two more bills:

The server. Chatwoot wants about 4 GB of RAM to run comfortably: the entry plan at Hostinger ($6.49/mo in year one, $11.99 on renewal) covers it. Plan details in which VPS you need.

WhatsApp separately. This catches people out: connecting WhatsApp to any professional tool — Chatwoot or otherwise — requires going through the official WhatsApp Business API, and Meta charges per conversation. Self-hosting doesn’t make that cost disappear; it’s the same charge you’d pay with a commercial tool.

Pricing verified 6 September 2026. WhatsApp rates are set by Meta and vary by country and conversation type.

Plus the usual third bill: installation and maintenance. The full calculation on whether that pays off is in is it worth it for a small business?.

When it pays off and when it doesn’t

It pays off when the per-agent saving is real:

• Teams of three or more handling support. At €20-40 per agent per month, five people is €100-200 monthly against roughly $12 of server.
• Genuinely multi-channel support. If everything arrives by email, email is fine.
• Customer data you’d rather keep in-house.

It doesn’t pay off:

• If you handle everything alone. Many commercial tools have a free or very cheap single-agent tier. Building a server for that loses money.
• If your volume is three enquiries a day. The problem Chatwoot solves — conversations lost between channels — isn’t one you have.
• If nobody maintains the server. A support tool being down means customers with no answer, which is worse than most outages.

A warning about the free edition

Chatwoot has a community edition and paid editions, and not every feature is in the free one. Some reporting and advanced management capabilities sit behind the paid tier.

Before building anything, list what you genuinely need and check one by one that it’s in the community edition. It’s the check that saves the most grief with any open-source project that has a commercial edition behind it, and it applies equally to the rest of the open-source alternatives.

How it fits with email marketing

Chatwoot is support, not acquisition: it manages conversations that have already started. For campaigns and outbound communication you still need another piece — we cover that in Brevo for small businesses.

FAQ

Can I really connect WhatsApp? Yes, via the official WhatsApp Business API. It requires verifying your business with Meta and paying per conversation. It isn’t a shortcut to using your normal WhatsApp from a computer.

How many people can use it? No licence limit in the community edition. The limit is the server: with 4 GB, a small team has room to spare.

Is it useful for a physical shop? Yes, especially if you get enquiries by WhatsApp and email and more than one person handles them. Pulling it into one inbox prevents the classic “I thought you’d replied”.

Does it integrate with my CRM? It has an API and connects well to automation tools, so creating the CRM contact when a conversation opens is feasible. Expect fewer direct integrations than a large commercial tool offers.

What if volume grows a lot? Chatwoot handles high volumes, but it’ll want more server. That’s a good problem: by then, the saving against per-agent pricing will be enormous.
