Codeen

Codeen is a fast, mobile-friendly agentic development environment built to run many coding agents at once. Key features: • Run multiple coding agents like Claude Code and Codex in parallel • Give each branch its own isolated git worktree • Built-in network proxy for watching and mocking requests • Device emulators and simulators, already configured • Real-time device mirroring and phone-based agent control • Built-in logging and automatic environment detection Codeen gives every agent its own worktree, so one repository can hold many checkouts at the same time. Agents can branch, work, and merge side by side without stashing or switching branches. Each branch lives in its own folder, and because agents edit separate files, their changes rarely collide. When an agent finishes, you review the diff, open a pull request, and merge while the main branch stays clean. The built-in debugging proxy lets you see every request your app makes. You can watch requests and responses live, mock responses, map hosts, rewrite headers, hold requests at a breakpoint, or throttle and block traffic to test edge cases. It comes preconfigured for your emulators, simulators, and phones, so setup takes little effort. Pair your phone over your local network by scanning a code, with nothing extra to install. Requests stay on the local network and are signed, and every project and worktree appears in a single list. Codeen is built for developers who run several coding agents across multiple branches and want fast, organized parallel work. It suits mobile app teams testing on devices, backend engineers debugging network traffic, and anyone who wants to answer agent prompts away from their desk. Use it for feature branches, bug fixes, and parallel experiments that need isolated environments.
