Overview
OpenBitFun is an open-source desktop app with a built-in agent runtime. You pick a model, open a workspace and give the agent a goal; it plans the steps, calls tools and reports back. Four modes range from quick back-and-forth to splitting a big task among several agents, and a phone or browser can send instructions to a computer running a task. Mini Apps let you build small tools by describing them.
It pairs a Rust agent runtime with a desktop app, and you build small Mini Apps by describing them to the agent.

Features
From the creator's documentation.
| Feature | What it does | Runs |
|---|---|---|
| Four working modes | Four modes, from quick feedback loops to complex work split among several agents | Your computer |
| Mini Apps | Describe a small tool and the agent builds it, with its own interface and chat | Your computer |
| Custom agents | Pick a model, define a role, and add tools through MCP, Skills and Hooks | Your computer |
| Remote control | Send instructions and answer approval requests from a phone or browser | Official Relay |
| SSH workspaces | Work on a remote host, through a jump host, or inside a container | Remote host |
| Model access | Configure a model in Settings, such as OpenCode Zen (free models or pay-as-you-go) or OpenCode Go | Model provider |
Good to know
You want one desktop workspace where an agent can plan and carry out a task in your project. OpenBitFun keeps the session, lets you pick how much structure the agent uses, and shows progress on a task board.
Limits
- You must add a model under Settings → Models first; OpenCode Zen offers free models or pay-as-you-go access.
- Controlling a computer from your phone uses the official Relay and sign-in with an OpenBitFun account (GitHub or an email code).
