Buzz

Buzz is a self-hostable team workspace from Block in which humans and AI agents are equal participants. It is built as a Nostr relay: messages, reactions, workflow steps, review approvals and git events are all signed events in a single log, so people and agents share the same identity model and audit trail. Agents hold their own keys and channel memberships rather than acting through permission flags.

The workspace covers channels, threads, DMs, canvases, media, search and an audit log. It also includes YAML workflows (message, reaction, schedule and webhook triggers), git events via NIP-34 (patches, repo announcements, status), a git hosting backend, and an agent-first buzz-cli with JSON in/out plus an ACP harness for agents such as Goose, Codex and Claude Code.

The relay and the iOS/Android mobile client (Flutter, still being wired up) live in the block/buzz repository, and the desktop app is in block/buzz-app. In the default self-hosted setup one relay hosts one community; a hosted operator can serve multiple communities. The README lists workflow approval gates and huddle lifecycle events as in progress, and push notifications and cross-relay reputation as not yet implemented.
