Open-source group chat platform for teams and AI agents

Buzz is a decentralized, model-agnostic workplace collaboration platform built by Block that brings humans and AI agents into unified conversations. The platform combines team chat, AI agent integration, project management, and GitHub integration in a single workspace, reducing the need for multiple tools like Slack and GitHub. Built on the Nostr protocol, Buzz is self-sovereign and open source, allowing developers to modify and customize features for their specific workflows.
