Same job. Very different ownership.
They all put an AI support agent on your site. The difference is what you keep — your code, your data, your infrastructure — and a bill that doesn’t meter every message, seat, or model call.
Open & self-hostable
Own the stack like Chatwoot, with AI built in from day one — not a closed SaaS like Chatbase or a developer project like Botpress.
No metering surprises
Self-host and skip message credits (Chatbase), per-seat fees (Chatwoot), and separate AI-Spend on top of the plan (Botpress).
White-label by default
Six themes and full branding are standard — not a paid add-on (Chatbase, Botpress) or locked to Enterprise (Chatwoot).
Comparison reflects publicly available information as of mid-2026. Chatbase, Botpress and Chatwoot are trademarks of their respective owners; features, licensing and pricing on all sides change — verify current details before relying on them.
An honest read on the field.
ChatterMate
Open-source, AI-native, brand-first
Best if you want a polished, on-brand AI agent you can host yourself, with human handoff and analytics built in — and no per-message or per-seat meter as you grow.
Chatbase
Closed SaaS, fast to start
A quick, fully-managed way to launch a docs-trained bot. Fine if you never need self-hosting and are comfortable with metered credits plus add-on fees for branding and extra agents.
Botpress
Developer-first, deep control
Powerful visual + code builder for teams with developer resources. The trade-off is complexity and a base plan plus separate, usage-based AI-Spend that makes budgets harder to predict.
Chatwoot
Open-source omnichannel inbox
A strong self-hosted shared inbox across many channels. AI (Captain) is a newer add-on, self-hosting needs DevOps, and branding / SSO live behind the commercial Enterprise tier.
Try the one you can actually own.
Start free with 300 chats, or clone the repo and self-host in an afternoon. No lock-in either way.
