Show HN: I built a UI to manage Claude Code worktrees

https://github.com/stravu/crystal
4•jbentley1•4h ago
I love Claude Code but got tired of having nothing to do while I waited for sessions to finish, and managing multiple sessions on the command line was getting annoying and I kept losing track of the tabs. I originally built a quick and dirty version of this for my own use, but decided to polish it up and make it open source.

The idea is that you should be able to do all your agentic coding without leaving the tool or needing to go back to a traditional IDE. You can view the diffs, run your program, and merge your changes back.

I support OSX and Linux right now, but could add Windows support if people want it. I appreciate any and all feedback.
