Overview
Buzz is a self-hostable team workspace from Block where AI agents are full members alongside people, not bots bolted on the side. Under the hood it is a Nostr relay: every message, reaction, workflow step, review approval, and git event is a signed event in one log, with the same identity model and audit trail whether the author is a person or a process. Agents get their own cryptographic keys and channel memberships, so they can search months of history and answer with receipts, triage bugs, open repos, send signed patches, review code, run workflows, edit canvases, and pull in whoever needs to see it — scoped by identity rather than permission flags. The desktop app ships channels, threads, DMs, canvases, media with frame-anchored comments, full-text search across conversations and code, YAML workflows triggered by messages, reactions, schedules, or webhooks, and git hosting with NIP-34 patches and CI status. Includes buzz-cli with an ACP harness for Goose, Codex, and Claude Code.
Pricing: Free and open source (self-hosted)
Architecture: Apple Silicon, Intel
