A new coding harness with a lightweight design and remote execution support
About
- A native GUI coding harness built with C++ and Dear ImGui, running on Windows, macOS, and Linux. Used by connecting a local model or an external model API
- Supports parallel work by subagents and remote execution; models with vision can look at the screen, click, and type to test and debug GUI apps
- Designed to avoid indefinite waits, with timeouts applied to network requests and permission responses. Long-running shell commands are moved to background tasks, and the agent checks their status periodically
- When a command is interrupted, the whole process tree is terminated with it, preventing leftover child processes. The GUI also stops redrawing the screen while idle, reducing resource usage
- Model providers must be configured manually, and Claude subscriptions cannot be used. Offers a free Community Edition and a paid Professional Edition with built-in remote execution engines for multiple platforms
