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.
Re:Compare Claude Code and Codex with one click

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.

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.

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.
Re:Crystal v0.3: Codex support in Git Worktrees
on Monday September 22, 2025 @10:36AM (#45334074)
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.

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.

Re:Open Source worktree manager for Claude Code

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.

I honestly think all of these VSCode forks are moving in the wrong direction. They are horseless carriages, old-style tools with AI stapled to the side. I'm trying to figure out what agentic coding should look like, and I built Crystal as an agent management platform first, IDE second.

I built Crystal to manage Claude Code agents in worktrees instead of using an IDE that only lets me work on one thing at a time.

Re:Claude Code Introduces Specialized Sub-Agents

This is great. I hope that they expose the configuration through the SDK, but right now it works with Crystal (https://github.com/stravu/crystal) if you configure them in the CLI.
I'm working on a proper config screen for them that just modifies the agent files directly, and a future release will also give special formatting for agent output.

Re:Spending Too Much Money on a Coding Agent

My Claude Code usage would have been $24k last month if I didn't have a max plan, at least according to Claude-Monitor.
I've been using a tool I developed (https://github.com/stravu/crystal) to run several sessions in parallel. Sometimes I will run the same prompt multiple times and pick the winner, or sometimes I'll be working on multiple features at once, reviewing and testing one while waiting on the others.
Basically, with the right tooling you can burn tokens incredibly fast while still receiving a ton of value from them.

Crystal is a re-imagining of what an IDE means when AI drives development. Traditional IDEs are designed for deep focus on one task at a time, but that falls apart when you have to wait 10-20 minutes for an agentic task to run. Crystal lets you manage multiple instances of Claude Code so you can inspect/test the results of one while waiting for the others to finish.
