Block, the payments company led by Jack Dorsey, has released Buzz, a decentralized collaboration platform that blends messaging, GitHub-style workflows, and AI agents into a single tool. Built on the Nostr protocol, Buzz is positioned as a direct competitor to both Slack and GitHub.
What Buzz does
Buzz combines real-time chat, code repository management, and automated AI agents in one interface. Users can send messages, manage pull requests, and trigger AI-driven tasks without switching between apps. The platform is designed for developers and teams who want a unified workspace that doesn't rely on a central server.
Built on Nostr
Nostr is a decentralized protocol that enables censorship-resistant communication. By building Buzz on Nostr, Block is betting on a future where users control their own data rather than handing it over to a single company. This approach sets Buzz apart from Slack and GitHub, both of which are centralized services.
Competing with Slack and GitHub
Slack dominates team messaging, while GitHub is the leading platform for code collaboration. Buzz aims to pull users away from both by offering a combined experience with added AI capabilities. The tool is still early-stage, and Block has not announced a public launch date or pricing details.
The move is part of Block's broader push into decentralized technologies. Jack Dorsey has long been a vocal advocate for open protocols and self-sovereign identity. Buzz represents the company's first major foray into workplace software outside of payments.
How developers and teams respond will determine Buzz's place in a crowded market.
