About BitFun

OpenBitFun is an open-source agent workspace available as a GitHub repository. It combines an agent runtime written in Rust with a desktop application, CLI, and mobile and browser access. It is designed to handle software development tasks as a code agent and also support general work beyond coding.

Users can select from four Agent Harness modes called Minimal, Standard, Ultimate, and Creative, which structure how tasks are planned and carried out. Tasks can be started on desktop and continued from a phone or browser, including checking progress and responding to approval requests. It supports SSH connections to remote hosts and containers, and account sync between devices runs through a Relay server the user deploys. Users can also build Mini Apps to extend the workspace.

It suits developers and technical users comfortable using open-source tools from GitHub and managing their own deployment for remote access.
