Block launches Buzz: Open-source rival to Slack and GitHub

Block launches Buzz, an open-source, decentralized group chat platform for teams and AI agents, integrating communication, project management, and code sharing to rival Slack and GitHub.

Jack Dorsey’s Block has launched Buzz, an open-source, decentralized group chat platform aiming to rival established workplace tools like Slack and GitHub. Buzz combines communication, project management, code repositories, and automated workflows into a unified workspace, enabling seamless collaboration between employees and AI agents. Built on the decentralized Nostr protocol, Buzz is model-agnostic and self-sovereign, ensuring private and censorship-resistant communications. AI agents are treated as independent team members, each with their own cryptographic identities, permissions, and activity histories. Buzz seeks to reduce dependence on proprietary solutions by providing an open, transparent, and resilient environment for teams of all sizes. This launch reflects Block’s commitment to open-source collaboration as the importance of AI and human teamwork grows.
