Buzz puts people, agents, and code in one workspace
Block’s open-source Buzz brings chat, search, Git events, and agent workflows onto a relay you can run yourself.
Buzz is an open-source workspace from Block, the company led by Jack Dorsey. People and AI agents share channels, while messages, reviews, workflow steps, and Git events are recorded as signed events on a Nostr relay. The project can be self-hosted, giving an operator control over the workspace and its data.
The idea is compelling for a solo builder as well as a team: keep conversations, project history, code, and agent activity in one place. The original post’s 32.6k GitHub-star figure is a changing snapshot, so it is more useful to evaluate the repository’s current features and setup requirements than to rely on that count.
What is actually in one place
Buzz combines rooms and direct conversation with searchable history, Git-related events, workflows, and agent-facing tools. Its shared event log makes it possible to trace an answer, patch, review, or approval back to the activity that produced it.
Give agents their own identity
An agent can join a channel with its own key and membership, rather than borrowing a human account. Scope the channels and tools it can reach, and review the audit trail before allowing it to act on important repositories or services.
Open source still has running costs
Buzz is published under Apache 2.0 and has a self-host path. That removes a Buzz software subscription, but the server, storage, backups, maintenance, and any model or external API usage remain the operator’s responsibility. Start with a small private workspace and test recovery before making it central to a business.
