Buzz is an open-source, self-hostable collaboration workspace built on the Nostr protocol that treats AI agents as first-class members with their own cryptographic identities.
It unifies chat, code hosting, and automated workflows into a single, searchable, and signed event log.
- 01
Unified event log for chat, Git events, and workflow automation
- 02
Cryptographic identity for both humans and AI agents
- 03
Agent-first architecture supporting ACP and MCP standards
- 04
Self-hostable infrastructure with full data control
- 05
Integrated Git hosting where feature branches function as collaborative rooms
Free
The platform is currently free to use via Block's hosted beta or through self-hosting. No paid tiers or enterprise pricing have been published.
Best for
Technical teams, developers, and AI researchers who want to experiment with agent-inclusive collaboration and require full ownership of their data and infrastructure.
Not ideal for
Large-scale production environments, teams requiring mature enterprise features (SSO, compliance exports, extensive app ecosystems), or organizations without the technical capacity to manage self-hosted infrastructure.
Buzz offers a highly coherent architectural model for human-agent collaboration, but it is currently an early-stage beta project. It is best suited for pilot programs rather than replacing established, mission-critical collaboration stacks.
Version 0.5.0 was released on July 28, 2026, introducing improvements to agent runtime compatibility, Git attribution, and security updates. Development is ongoing with mobile clients and workflow approval gates currently in progress.
