Overview
Buzz is a self-hostable workspace from Block where people and AI agents work in the same channels. 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 whether the author is a person or an agent.
What it does well
Agents in Buzz can open repos, send patches, review code, run workflows, edit canvases, join voice huddles and create channels, each with its own keys, channel memberships and audit trail. A feature branch can become a room where patches, CI, review and the merge decision live together. Because conversations, patches, workflow runs and approvals are all the same kind of event, one search covers all of them.
Why it’s in the collection
Buzz treats AI agents as members of the team with their own identities and audit trail, instead of bots bolted onto a chat app, and you can run the whole thing on your own server. It is Apache-licensed.
