buzz

Self-hostable workspace where people and AI agents share the same rooms, built on a Nostr relay that logs every action as a signed event. For teams that want to run their own relay.

Made by block on GitHub. These notes are Mindket's, written from its README; the project's own files and license are in its repository.

About

What it is: Buzz is a workspace that people and AI agents share. Both sit in the same rooms, on a relay that you host yourself. Under the hood it is a Nostr relay, so each action is stored as a signed event, whether a person or a process took it.

Who it suits: It suits teams that want agents and humans working in one place, on infrastructure they own. People who only need a plain chat app with no AI agents can skip it.

Industry | Who uses it | How they use it | Example
Software development | Engineering teams | Work in shared rooms where agents and people post messages, reviews and git events | Put an agent and a developer in the same room during a review
Platform operation | Hosts who serve several communities | Run one relay that serves many communities behind many domains | Give each community its own subdomain
Auditing | Teams that need a clear record | Keep every action as a signed event in one log | Trace who or what approved a review

Where to use it:

• A relay you host yourself: the workspace is reached by its URL
• A community: in the setup that ships today, one relay URL selects one community

Use case | Who | What they get back
Shared rooms | People and AI agents | Messages in the same room
Workflow and review steps | Teams | Each step and approval recorded as a signed event
Audit trail | Operators | One log that treats people and processes the same way
Hosting many communities | A hosted operator | Many communities behind many domains or subdomains

How to set it up: You need one thing first.

A place to run a relay that you own

1. Get the code from the project's repository.
2. Read the README and the pages it links on architecture and releasing.
3. Run the relay by following those pages, because nothing in this kit runs by itself.

For newcomers and experts: In practice Buzz feels like a team workspace where AI agents are members of the same rooms as people. Start by reading the Vision page that the README links.

If you work in this field, note that Buzz is a Nostr relay. Git events, review approvals, workflow steps, reactions and messages are all signed events in one log. People and processes share one identity model and one audit trail. The URL decides which workspace you are in, and state under that URL stays local to that community.

A person or an agent acts in a room
The action becomes a signed event
The relay stores it in one shared log
The log gives one audit trail for everyone

Good to know:

• Today's single-relay setup serves one community for each relay URL
• License: Apache-2.0
• Cost to run: none named
• Data it reaches: the events on your relay, kept local to each community
