You can use Crystal (https://github.com/stravu/crystal) to run Codex and Claude Code at the same time and just pick the best result.

We built a tool to use Git Worktrees to manage all of our in-progress agents. It's expanded from just Claude Code to having Codex support, and I'm loving running them side by side. They see things from different angles, make different UX choices, find bugs the other one doesn't, etc.

Just having the model variety is helpful, it is my default way to work now for every prompt I submit.

Check out Crystal, similar but open source https://github.com/stravu/crystal

I do this every day! In fact, I built a new type of IDE around this (https://github.com/stravu/crystal) and I can never go back.

I've built something very similar but am further along (https://github.com/stravu/crystal). I understand the desire to do your own thing, but if you are interested in joining forces and contributing I would love to have you. I think we were thinking along very similar lines.

I use Crystal which archives all my old claude code conversations, I've had to do this a few times when I threw out code that I later realized I needed.

A new type of development environment for working with agents

https://github.com/stravu/crystal

It supports Claude Code and Codex, but has you constantly working on multiple features in Git worktrees. This way you are always able to stay busy while waiting on your agents.

It has built in tools for review, such as a diff viewer, and a quick button to run your application in different worktrees for testing. It has completely transformed the way I work.

Yeah I didn't realize there was also a Ruby dialect called Crystal until we had already launched. Not that I could think of a better name anyways.

We've added support for Codex in Crystal, meaning you can now run Codex sessions alongside Claude Code in isolated git worktrees for parallelized development.

This is a great list for people who want to smugly say "Um, actually" a lot in conversation.

Based on my brief stint doing data work in psychology research, amongst many other problems they are AWFUL at stats. And it isn't a skill issue as much as a cultural one. They teach it wrong and have a "well, everybody else does it" attitude towards p-hacking and other statistical malpractice.

I am by no means an expert on this, but was reading this about the amoloid hypothesis this morning: https://www.astralcodexten.com/p/in-defense-of-the-amyloid-h...

He addresses the specific reasons that the mouse results don't translate, but the interesting part to me is that the scientific community seems to be behind the amyloid hypothesis while the media likes to run with any story that refutes it.

It's fully open source, you can manage Git Worktrees, review diffs, run your application, and push your branches all in one place. It is a re-imagining of what an IDE should be in 2025.

New comment by jbentley1 in "Open Source worktree manager for Claude Code"

jbentley1 — Wed, 13 Aug 2025 13:39:14 +0000

I originally built this for myself because I didn't like waiting around for Claude Code to finish and I didn't want to mess with a bunch of terminal windows to use worktrees so I built a GUI. Then I started adding more features, diff view, script running, and more and my team and I decided it needed to be shared as an open source project.

Excited to hear what the HN community thinks.
