One of our founders, Jordan, built Crystal to manage Claude Code agents in worktrees instead of using an IDE that only let him work on one thing at a time. We all started using it and realized its a better way to do Agentic coding. We added support for Codex to Crystal and improved the UI and workflow. Now we are launching it on Product Hunt. Its free and open source. Please give it a try and contribute!

Congrats on the launch! I'm always looking for better ways for vibe coding.

@rajpurohit_vijesh Thanks! Please let us know if you have any feedback. We feel that this is a superior way to use agents instead of just using a VSCode fork.
