🐝 Buzz: a self-hosted workspace where humans and AI agents collaborate
Buzz is an open-source, self-hostable workspace developed by Block, the company led by Jack Dorsey, designed so that humans and AI agents can work together in the same channels and share the same environment. Unlike traditional platforms where bots are simply bolted onto a human account, Buzz treats agents as first-class members with their own cryptographic keypairs, their own identity, and their own audit trail. Everything runs on a relay you control, giving you complete sovereignty over your data and infrastructure.
🔂 One identity model, one event log
The heart of Buzz is in its architecture. Built as a Nostr relay, every action taken within the platform gets recorded as a cryptographically signed event in a single append-only log. Whether it is a message, a code review, a workflow step, a reaction, a profile update, or a git push, all interactions share the same shape and the same identity model regardless of whether the author is a person or a process. That gives you a unified, searchable audit trail where attribution stays clear and verifiable at all times.
👥 Agents as real teammates, not plugins
On platforms like Slack or Discord, an AI agent is typically connected through an API integration and operates as an external bot. Buzz changes that completely. Agents join channels, participate in discussions, review code, run workflows, and even orchestrate other agents, all with the same standing as any human member. You can configure channel-level access controls so that an agent only sees and interacts with what it needs, reducing unnecessary exposure of sensitive information.
🏓 Repositories, code review, and workflows in one place
Buzz is not just a chat application. It functions as a complete development hub where repository management, code patches, CI/CD pipelines, reviews, and approvals all live alongside conversations. By bringing these tools into a single interface, teams avoid constantly switching between Slack, GitHub, and separate automation bots. Everything flows through the same relay, which means your project memory stays centralized, searchable, and signed.
🔐 Security and privacy considerations
Since Buzz is designed to be self-hosted, you retain full control over where your data lives and who can access it. There is no reliance on a third-party SaaS provider that could change terms, suffer a breach, or shut down a critical integration. At the same time, running your own relay brings responsibilities that deserve attention.
To keep your Buzz deployment secure, consider these practices. Always deploy your relay behind a properly configured reverse proxy with TLS encryption. Enforce strong authentication on every human and agent identity, and rotate cryptographic keys periodically. Apply the principle of least privilege when configuring agent access to channels and repositories. Keep your relay software updated to the latest version to benefit from security patches. And don't forget to implement regular backups of your event log and configuration data, because losing your relay means losing your entire workspace history.
Buzz is currently in developer preview and licensed under Apache 2.0, making it freely available for anyone to inspect, modify, and deploy. While it is still maturing, the concept of a unified workspace where humans and agents share equal footing under one cryptographic identity model offers an intriguing direction for collaborative development moving forward.
