Jack Dorsey's company Block has launched Buzz, a free, open-source platform designed for teams of humans and AI agents to collaborate in a shared workspace. Built on the Nostr protocol, Buzz aims to rival Slack and GitHub by integrating chat, code repositories, and automated workflows.
Buzz provides cryptographic identities for both human users and AI agents, allowing agents to post, review code, and participate in conversations with defined permissions. The platform is model-agnostic, supporting various large language models and agent frameworks, including Anthropic's Claude Code, OpenAI's Codex, and Block's own goose.
Block selected the Nostr protocol to address identity challenges in multi-agent work, ensuring that each participant's identity, history, and reputation are self-sovereign and can traverse Nostr-compatible systems. The entire Buzz platform was developed using AI agents, reflecting Dorsey's view that AI fundamentally changes how companies are built and run.
The launch follows Block's significant workforce reduction and Dorsey's continued focus on open-source, decentralized tools, many of which are built on Nostr.
