OpenGUI

OpenGUI is a desktop and web application that acts as an AI coding agent, letting you connect an OpenAI-compatible model and work on files in any folder without installing separate tools. It includes its own execution layer with four core capabilities: reading files, creating new ones, editing specific sections, and running shell commands. Sessions are saved with full transcripts and queued prompts, so you can continue work across devices.

Designed for longer projects and everyday tasks like landing pages, presentations, scripts, and file changes, OpenGUI runs on macOS, Windows, and Linux. The maker reports building it in about four days using Claude and ChatGPT. It's free and open source under the MIT license, with no dependency on external coding-agent CLIs.
