Open-source desktop app for running multiple coding agents in parallel, each isolated in its own git worktree.
OpenAI Codex is a cloud-based autonomous coding agent that runs in a sandboxed environment. It can read codebases, write and edit code across multiple files, run tests, and submit pull requests—all from a natural language task description. Codex operates asynchronously, handling tasks in parallel while developers focus on other work. Built on OpenAI's reasoning models, it excels at feature implementation, bug fixes, and refactoring on real-world repositories.
