OpenBitFun
An open-source, highly customizable agent workspace, with a high-performance Rust runtime and a desktop app, that offers four agent-harness modes for different kinds of work and keeps a task moving across desktop, mobile and browser.
OpenBitFun is an agent workspace built around a Rust agent runtime and a desktop application, aimed at both software development and general-purpose work beyond code. An agent harness plans steps, manages context, calls tools, coordinates agents and combines their results, and the workspace offers four such harness modes: a minimal mode for quick, direct collaboration on a clear goal; a standard mode that plans, works through and checks a multi-step task; an ultimate mode that divides a complex task among several agents; and a creative mode for building Mini Apps or extending the workspace's own interface and capabilities.
A task can move between devices: started on a desktop, continued from a phone, or checked and approved from a browser, with the interface adapting to one, two or three-panel mobile layouts, and further device-extension support planned for wearables.
Version 1.0.0 is not data-compatible with the earlier 0.2.x line; a separate data migrator tool is provided to move data from those releases.
