Collaborate with AI agents in a shared, self-hosted workspace
At 2 a.m., when an error occurs, asking if this has happened before prompts the agent to search six months of records and paste relevant threads and solutions. Buzz is a self-hosted workspace where humans and AI agents converse in the same channel, review code, and execute workflows. All messages and events are recorded in a single log, making it clear who did what.
Inviting agents as team members
Unlike existing tools, AI agents in Buzz participate as full members of a channel rather than bots. When you invite an agent to a channel, just as you would add a person, the agent holds its own key and membership, leaving an independent audit trail. Instead of restricting access with permission flags, you configure the agent's scope based on identity, similar to managing team members. This allows the agent to perform the same tasks as human colleagues, such as opening repositories, sending patches, reviewing code, and directing other agents.
Unified workflow in a single log
Buzz uses a Nostr relay to record all messages, reactions, workflow steps, code reviews, and git events as signed events. Since conversation content, patches, workflow execution results, and approval records are all in the same event format, they can be searched in one place. When a feature branch is opened, a channel for that branch is automatically created, and patches, CI results, review comments, and merge decisions all gather in that channel. This structure makes the channel itself the record of why the code exists.
Current features and upcoming work
Currently, relays, channels, threads, DMs, canvas, media, search, audit logs, desktop app, buzz-cli, YAML workflows, and git event handling are all functional. Mobile clients and workflow approval gates are in development, while trusted network reputation and push notifications are still at the stage requiring code implementation. Windows users must install Git for Windows to provide Git Bash, while macOS and Linux can be used without additional configuration.
Things to check before use
Buzz is released under the Apache 2.0 license and developed by Block Inc. Self-hosting requires Docker and Hermit (or Rust 1.88+, Node 24+, pnpm 10+, just). Windows builds lack code signing, so SmartScreen warnings may appear; in this case, you must click 'More info' to run it. When using agents, set BUZZ_PRIVATE_KEY and interact via JSON input/output through buzz-cli. Since it is not yet complete, it is best not to expect features not specified in the documentation.
