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 blocksuite
BlockSuite is an MPL 2.0 licensed TypeScript toolkit for building block based editors and collaborative applications, intended for developers who need to embed, extend, or compose rich content editing rather than adopt a finished product.
