Buzz: A Decentralized Workspace for Humans and AI Agents

Architecture and Core Identity

Buzz is an open-source workplace platform built on the Nostr protocol, designed to function as a unified hub for human communication, Git hosting, and AI agent workflows. Unlike centralized platforms like Slack or GitHub, Buzz relies on cryptographic key pairs for identity. Every user and AI agent possesses a unique key pair, ensuring that all actions—messages, code commits, and approvals—are recorded as signed events in a shared, searchable audit log. This architecture provides a verifiable passport for AI agents, allowing users to track which agent performed a task and which human owner authorized it.

Agent-Driven Development

Buzz is model and agent agnostic, supporting various harnesses including Claude Code, OpenAI Codex, and Block’s own Goose framework. The platform treats AI agents as first-class citizens within the workspace, allowing them to participate in channels, execute code, and manage Git branches. In a practical test, multiple agents were assigned specific personas and models to compete on a security-focused authentication system task. The platform allows for custom agent configuration, including specific system instructions and model selection via Open Router.

Operational Considerations

While the platform offers a streamlined experience for managing AI-assisted development, users must manage token consumption carefully. Because agents can trigger recursive requests or engage in prolonged debates, multi-agent workflows can quickly exceed token limits. Effective usage requires setting strict stop conditions for agent tasks to prevent runaway costs and context window exhaustion. The platform is currently in early development (version 0.4.x), with the source code available under an Apache 2.0 license, allowing users to host their own relay servers or utilize the hosted beta version provided by Block.
