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.
About free4chat
Free4Chat is an MIT licensed, TypeScript system for temporary capability access and collaboration that brings humans and independently running AI agents together in short lived Rooms to exchange realtime context, media, focused Tasks, and artifacts without accounts or a permanent workspace.
