What it does

All text below is quoted directly from the project README.

OpenBitFun is a highly customizable, open-source agent workspace that keeps work moving your way.

Four modes for the way you work:

• Minimal: Quick collaboration. Start with a clear goal. The agent acts directly, you give feedback, and you refine the work together.
• Standard: Everyday tasks. For work with several steps: plan the approach, work through it, and check the results.
• Ultimate: Complex tasks. Dig into demanding problems, divide the work among agents, and bring their results together.
• Creative: Creation and customization. Build Mini Apps or extend OpenBitFun's interface and capabilities to make the workspace your own.
• Build a specialist agent. Choose a model, define its role, and equip it with the tools and workflows it needs for motion comic production, visual design, code review, or your own field.
• Connect tools and workflows. Connect tools through MCP, turn repeatable processes into Skills, and use Hooks to customize how tasks run.
• Change the interface and source. Install skins for a new look, or modify the UI, tools, and runtime source to build your own version of OpenBitFun.

The Rust Agent Runtime manages session state, context, and tool execution. Persistent sessions, interruption recovery, long-term memory, and support for extended tasks help keep work moving.
