Block launches Buzz, an open source collaboration workspace on Nostr protocol for humans and AI agents to share messages, code repositories, workflows, and more
Buzz arrives as collaboration products expand beyond chat and documents into shared environments for AI-assisted work. Anthropic’s earlier Projects feature for chats, documents and code illustrates the parallel push to organize multiple work artifacts around an AI system.
Its Nostr foundation also places the release in the longer decentralization arc reflected by Bluesky’s open-sourcing of its Ozone moderation tooling, where participants can have more scope to operate services independently.
First-order effects
Developers and teams can use a free, open-source workspace to exchange messages, repositories and workflows with both people and AI agents in the same environment.
Block becomes a provider of collaboration tooling built on Nostr, extending the protocol’s use beyond a narrower messaging or social context.
Second-order effects
Centralized AI-workspace vendors face a clearer alternative for teams that value open-source tooling and protocol-based participation alongside agent-enabled workflows.
The product raises the practical importance of portable workflow, repository and message integrations: a collaboration surface is more useful when its artifacts and agents can move across participating tools.
Third-order effects
If these workspaces gain adoption, collaboration software could split more sharply between tightly integrated proprietary suites and protocol-based layers that let organizations assemble their own clients, agents and services.
Bringing AI agents into shared decentralized workspaces makes governance—permissions, accountability and moderation—a core product-design issue rather than a separate administrative function.
The trend: Buzz is one data point in the shift toward agentic work surfaces that combine collaboration artifacts, AI participants and more open underlying infrastructure.
we're launching BUZZ! a new groupchat platform for teams of people and agents of all sizes, built to reduce our dependency on slack and github. model-agnostic, decentralized, self-sovereign, and open source. 🐝 https://buzz.xyz/
Jack Dorsey just opened another front in the war on SaaS lock-in. Buzz is live: a new group-chat / workspace for teams of people and AI agents, built by Block (block/buzz on GitHub). Jack's pitch: • Reduce dependency on Slack and GitHub • Model-agnostic • Decentralized
i've been testing this for a week. the agent integration is great. i connected my claude code subscription, spun up an agent, linked my github in the chat, and now i can reference my repos and share builds directly.
Buzzing! The thing I love about this one is that there's still so much left to discover. When your colleagues and your agents share the same space, what does that actually feel like? What gets easier? What gets weirder? What are the ergonomics of working this way, and which
This actually looks incredibly promising and could replace Slack for lot's of teams. Jack basically took slack's best features & discord's community aspect and made it agent native. I'll be testing with @feldarai team

Excited to share what I've been working on lately. Ever since I re-joined block i've been wanting change the lonely experience of working with AI agents. We are launching Buzz, a sovereign, open source, model agnostic, AI co-work platform, where teams of humans and agents work
