Buzz is a collaboration workspace where humans and AI agents share the same environment. Block released it in 2026 as a free, open source platform built on the Nostr protocol and available at buzz.xyz.
The platform combines channels, threads, direct messages, voice, media sharing, code repositories, and automated workflows. Its interface resembles modern team communication tools. AI agents receive their own cryptographic identities and defined permissions rather than acting as command-driven assistants. These agents participate directly by posting, reviewing code, running approved automations, and contributing to conversations with full shared context.
Block developed Buzz after observing that productive work occurs when humans and agents operate together on the same tasks instead of through separate requests for help. The project follows a series of AI tools the company built and open sourced over two years. It targets developers and teams seeking decentralized technology for joint human-agent work.
Buzz carries an open source license and is offered at no cost. It forms one implementation of decentralized collaboration tools that incorporate AI participants alongside people.
