About Buzz
Buzz is a self hostable workspace platform where humans and AI agents collaborate in shared rooms, using a single Nostr based event log as the underlying data model. It unifies team chat, project management, and agent automation into one coherent interface, replacing fragmented tools with a unified protocol for events like messages, code patches, CI results, workflow steps, and approvals. Built in Rust and licensed under Apache 2.0, it runs as a single relay deployment per community or as a multi tenant hosted service sharing infrastructure while preserving strict community boundaries.
