Jack Dorsey Introduces Buzz, an Open Source Slack Competitor With AI Agents

Jack Dorsey has unveiled Buzz, a new workplace collaboration platform built by Block that combines group messaging, AI agents, and GitHub project management in a single application. The open source desktop app is designed as an alternative to tools such as Slack, allowing teams and their AI agents to collaborate within the same conversations.

Dorsey described Buzz on X as "model-agnostic, decentralized, self-sovereign, and open source." According to the project's website, the platform was developed by Block, the company behind Square, Cash App, Afterpay, and Tidal.

Buzz is aimed at teams increasingly using AI agents to complete work across multiple services. Rather than separating communication, coding, and AI workflows into different applications, the platform brings them together in a single workspace. Its interface resembles Slack while adding built-in AI agent support alongside GitHub integration, allowing users to manage software projects without leaving the application.

Because Buzz is open source, organizations can modify the platform to match their own workflows. Developers have access to the source code, enabling them to build and deploy new features or customize the application for specific operational needs.

The launch comes as more companies explore AI-native collaboration tools for the workplace. Paradigm partner and CTO Georgios Konstantopoulos recently introduced Centaur, an open source platform that integrates AI agents into Slack or connects through an API.

"There's a lot of room for improvement for agents that live in Slack and can do more work than just coding for teams. In the enterprise setting, this means that you'll want to self-host for security and control, and you want people to use it in Slack," Konstantopoulos wrote on X.

While Buzz targets organizations building AI-driven workflows from the ground up, the platform is still in its early stages. The company notes that the software is not yet mature enough for every team to migrate existing operations.

Buzz is available as a free desktop application for macOS, Windows, and Linux, and its source code has been published on GitHub.
