WebCodex

WebCodex is a development environment tool that connects cloud AI agents to local repositories and tools.

WebCodex connects cloud AI agents like ChatGPT and Claude to local repositories, Git checkouts, and development tools on your own machines. Users can ask their assistant to inspect repositories, modify code, run tests, and use Git without moving projects into a hosted workspace. The platform includes a Desktop app, CLI, Server, and Runner in a unified package. It supports long-running work and human review through a Runtime Console and Git diff reviews. It is designed for developers who want to use AI coding agents while keeping their code locally.
