Chatwoot

Free: The self-hosted Community Edition is free under MIT: live chat, email, social and messaging channels, help center, canned responses, labels, auto-assignment, automation and reports. Chatwoot Cloud also has a free Hacker plan for up to 2 agents with 500 conversations/month, website live chat only and 30-day data retention. Cloud's Startups plan is free for open source projects on request.

Self-hosted: Rails app plus a Sidekiq worker, Postgres (the compose file uses pgvector) and Redis, with S3-compatible storage for uploads; Chatwoot recommends at least 4GB RAM and 2 CPU cores for production. Paid self-hosted plans unlock code in the proprietary enterprise/ directory: Premium Support at $19/agent/month adds Captain AI (runs on OpenAI's GPT models), custom branding, agent capacity, roles & permissions and priority email support; Enterprise Edition at $99/agent/month adds SSO/SAML and SLA policies, plus phone support. Licenses are bought per agent from the Super Admin panel; there are no instance-level plans. Enterprise self-hosted plans are not refundable.

Paid: Chatwoot Cloud, per agent per month as listed (the page shows no monthly/annual toggle), 15-day free trial: Startups $19 (unlimited conversations under fair use, all channels except voice, help center, 300 Captain AI credits, 1-year retention), Business $39 (adds voice, teams, automation, custom attributes, pre-chat forms, SLA, 500 credits, 2-year retention), Enterprise $99 (adds SSO, audit logs, agent capacity, branding removal, 800 credits, 3-year retention). Extra Captain credits cost $20 per 1,000. A dedicated account manager needs 20+ agents.
