Getting a "can't verify the developer" warning?
If you see a warning on first launch, go to System Settings > Privacy & Security and click "Open Anyway". Open source software usually isn't signed with an Apple developer certificate, which is normal.
Clicking "Download" takes you to a source confirmation page first; the download starts after confirmation.

Risk notice
The Windows installer is unsigned and may be blocked by SmartScreen on first run. The project is still in early development, and some planned features are not yet implemented. Please use with caution in production environments.
Who it's for
- Teams that want a self-hosted collaboration platform and want to bring in AI agents
- Technical users interested in the Nostr protocol and event-log architecture
- Developers who need AI to participate in code review, workflow automation, and information retrieval
- Communities or organizations that value data autonomy and audit trails
Who it's not for
- Users who need mature, stable, fully code-signed commercial software
- Users who do not want to deploy or maintain a relay service themselves
- Teams that only need traditional instant messaging and don't need AI collaboration
- Teams with strong dependencies on features that are not yet complete

First run
By default, Buzz connects to ws://localhost:3000. If you don't have a local relay, you need to set one up first (see the "Build & run from source" section in the project README), or point the environment variable BUZZ_RELAY_URL to an available relay, then start the app.
