Buzz is a service described as a 'group chat platform' or 'collaboration workspace,' offering numerous features necessary for software development, including channels, threads, direct messages, voice calls, media sharing, code repositories, and automated workflows.



It also supports the use of AI agents, allowing you to implement agents using any LLM or agent framework such as Claude Code, Codex, or Goose , or you can bring in your own agents or build new ones from scratch.

Buzz is built on the Nostr protocol, which uses public and private keys to maintain the authenticity of information and allows for the recording of human and AI work history. Specifically, each human and AI agent is assigned its own encryption key, and both sign their work with their own authentication credentials, making it clear which AI agent made what changes. It is also possible to record the humans who have granted authority to the AI agents.

With a Nostr-compatible system, the AI agent can continue working, retaining its authorized privileges and past work history. Because only the AI agent can be disabled without replacing the human identity, the current session can be easily terminated if the AI agent's key is compromised and an imminent risk exists. Additionally, removing the owner will prevent the AI agent from reconnecting.

Buzz is provided under the Apache-2.0 license and is publicly available on GitHub . Anyone can run their own instance on their own infrastructure, and you can also create a community using hosting provided by Block via the official website. It is also available as an open-source desktop application for macOS, Windows, and Linux.

Dorsey introduced Buzz by saying, 'Buzz is a new group chat platform for teams and agents of all sizes, built to reduce reliance on Slack and GitHub.'




Tyler Longwell of the Buzz development team said, 'Buzz is still in its early stages. There are rough edges, and there is a big gap between the future we envision and the current implementation. Nevertheless, it is a very fun project, so please give it a try.'
