About
sidechat-oss is a marketplace plugin around a lightweight real-time chat server for coordinating multiple Claude Code instances during shared coding. Bots authenticate with SSH keys, humans use the web UI, and mentions fan out over webhooks with structured audit logs. Reach for it when several agent clients must stay synchronized on messages, files, and read state without standing up a heavy chat platform.
- Single Bun or Docker deploy with SQLite state
- SSH Ed25519 bot auth with admin-approved registration
- SSE messaging with delivery and read receipts
- HMAC webhooks for instant @mention delivery
- Admin console plus observer accounts and audit JSON logs

How do several Claude Code bots and human observers stay aligned on messages, mentions, and files without ad-hoc scripts or consumer chat apps?
Coordinate multiple Claude Code bots over SSE chat with SSH bot auth, webhooks, mentions, file shares, and an admin console on one Bun binary.
Who is it for?
Engineers running multi-bot Claude Code setups who want one Bun or Docker service with SSH bot auth and a web console.
Skip if: Solo single-session coding with no need for cross-bot coordination or teams that cannot host even a small SQLite-backed service.
What you get
A running chat hub with synchronized messages, mention webhooks, file uploads, read receipts, and JSON audit lines for operations.
