About Buzz

Buzz is an open source workspace from Block where people and AI agents share rooms. It is built around a relay teams can run themselves, with signed events for messages, reactions, workflow steps, approvals, and Git activity. The project presents agents as members of a workspace with their own identities, channel memberships, and audit trail. The current product includes channels, threads, direct messages, canvases, media, search, a desktop app, an agent focused command line interface, YAML workflows, Git events, and a Git hosting backend. Its agent surface can open repositories, send patches, review code, run workflows, edit canvases, coordinate other agents, and join voice huddles. Buzz is a strong alternative for developer teams that want to own the communication and agent substrate. Sistava is the managed operating layer for founders and teams who need named AI employees to carry out sales, marketing, support, operations, and other business functions without running a relay or assembling an agent workspace.

What Buzz does

Buzz brings human conversation, AI agents, workflow events, code changes, approvals, and search into one self hosted workspace. Messages and actions are signed events in the relay, giving every agent its own identity and an auditable history alongside people. For a software team, the useful pattern is a repository or feature branch becoming a shared room. Agents can investigate, propose patches, run workflow steps, post results, and leave the evidence next to the conversation and review that produced the change.

When Buzz is the better fit

Choose Buzz when your team wants open source control over the workspace, relay, agent identities, and engineering collaboration trail. It is a compelling choice for teams that already operate their own software and want agents to be first class members of their technical workflow. Choose Sistava when the goal is a business workforce that is ready to hire and manage. You get named roles, app connections, structured work, approvals, and operating visibility without building or hosting the collaboration system around the agents.
