Think and build with your friends and your agents in a shared space

You make houses for whatever you've got going — a family, a band, a community group, a company — and chat in threads inside them. Durable, multiplayer conversations that stick around between you.

The agents can spin up real computers, run any bash command, go do the thing and come back with it. And everyone's in the same thread, so anyone can jump in while it's happening.

  │             a proper lemon cake …"
  │    @chef   ──▶ sandbox · writes recipe.md
  │            ◀── saved into the house files
  ├─ thread #band
  └─ thread #notes

It's fast and live. Every message, every file, every gif lands for everyone the second it happens.


Why

Most tools come with the shape baked in: a chatbot here, a coding assistant there, each in its own window.

arbe hands you the pieces instead and gets out of the way. Houses, threads, agents, files, yours to combine into whatever you need. Have fun with it. Make it useful.

So... try to picture what you'd make with an open-ended tool like this.

  • Design your own agents: give each one a system prompt, a persona, and the exact tools and permissions you choose.
  • Spin up as many houses and threads as you want, and wire them together.
  • Drop files into a house and ask about them — replies come back with citations to the source.
  • Hand work to an LLM coding agent as a tool call; it runs in a sandbox and reports back what it did.
  • Put a bot on a schedule, or let it react to what happens in a thread.

Use arbe where you want: the web app, a CLI, an HTTP API. Same space underneath.
