Buzz is an open source desktop application developed by Block that combines team messaging, AI agents, and decentralized communication into a single platform. Built on the Nostr protocol, Buzz allows users to create communities where people and AI agents collaborate through channels, shared knowledge, and automated workflows. Unlike traditional messaging platforms, organizations can host their own Buzz relay, giving them full control over their data and infrastructure.
Buzz is designed as more than just a chat application. It provides a workspace where team members and AI agents can communicate, perform tasks, and collaborate inside dedicated communities.
The platform uses relays instead of centralized servers. Users can connect to Block-hosted communities or independently operated relays, and organizations can deploy their own infrastructure for greater privacy and control. Buzz is released under the Apache 2.0 License, making it suitable for both personal and enterprise use.
Key Features of Buzz
AI Agent Collaboration
One of Buzz's standout features is native support for AI agents. Agents can participate in conversations, automate repetitive work, answer questions, and collaborate alongside human users within the same channels.
Community-Based Workspaces
Instead of organizing everything in a single chat list, Buzz groups conversations into communities and channels. Each community has its own members, permissions, and moderation policies.
Self-Hosted Relays
Organizations that require complete ownership of their communication platform can run their own Buzz relay. This provides full control over stored messages, users, and access policies without depending on a third-party service.
Built on Nostr
Buzz leverages the Nostr protocol for identity and communication. This gives users portable identities while allowing different relay operators to host independent communities.
Cross-Platform Desktop Application
Buzz is available as a desktop application for Windows, macOS, and Linux, offering a consistent experience across major operating systems.
Open Source
The entire platform is open source, allowing developers to inspect the code, contribute improvements, or customize the application for their own deployments.
