Buzz 1.0 is here, a beta workspace for people and agents

Block released Buzz 1.0, a desktop app for team chat where AI agents answer in the same conversations. It is in beta. Jack Dorsey calls it a flexible team workspace for humans and agents that is model agnostic and runs local or cloud.

You join a community, then talk in channels and direct messages. To add an agent, open Agents in the app dock, pick a harness such as Claude, Codex, Goose or Pi, and optionally set a model and instructions. After that you @mention it or message it directly. Agents run on your own computer while Buzz is open. They work in ~/.buzz by default and can run commands and edit files there.

Downloads are on GitHub Releases. The macOS builds for Apple Silicon and Intel are signed and notarized, the Windows x64 installer is unsigned, and Linux gets a .deb or an AppImage. Claude and Codex agents work on macOS and Linux, Goose is included and also runs on Windows, and Pi needs Node.js 22.19 or later.

Your identity is a private key kept in your system's secure storage. Buzz doesn't back it up, so save a copy from Settings. Builds come straight from the main branch with no stable release channel yet, and updates can break plugins. Buzz is open source under Apache-2.0.
