Extension for JetBrains IDEs (PyCharm, IntelliJ, etc.)

[sundayj]

What feature would you like to see?

Feature Request

An official Codex extension for JetBrains IDEs—especially PyCharm and IntelliJ IDE, that brings Codex CLI’s capabilities into the JetBrains ecosystem.

Why is this feature important?

JetBrains IDEs are widely used by Python and full-stack developers for their powerful debugging, refactoring, and version control integrations. While Codex CLI and VS Code support are great, many developers rely on JetBrains tools daily. A native extension would make Codex more accessible and useful across a broader range of workflows.

Suggested Capabilities for the Extension

Main Features

• JetBrains Terminal Integration
  • Command suggestions and completions powered by Codex
• Version Control Integration
  • PR title and summary generation
  • PR code review assistance
  • Commit message title and summary generation
  • Commit-level code review

Nice-to-Haves

• Inline Code Suggestions
  • Real-time completions and intelligent suggestions as you type
• Context-Aware Refactoring & Documentation
  • Codex-powered refactoring suggestions
  • Auto-generated docstrings and inline documentation
• Multi-language Project Support
  • Seamless handling of Python, JavaScript, HTML, and other common stacks

Are you interested in implementing this feature?

I’d love to be involved in building this, though I likely wouldn’t have the bandwidth to fully own it myself. If someone else is interested in spearheading the effort, I’d be glad to support however I can, whether that’s contributing code, reviewing PRs, or helping shape the design.

Additional information

Even a minimal MVP—such as terminal and commit message integration—would be a huge win for JetBrains users. This could also pave the way for deeper IDE-native workflows powered by Codex.

I have been building a Visual Studio 22 and Jetbrains extensions that are 1to1 parity with the VS Code extension with the added abilities of VS22 like building etc and same with Jetbrains. If you want I would be more than happy to invite you to the repos (keeping them private until ready to release to OAI) and you can help me out with them if you'd like. I was hoping to have them released this week but IRL slowed me down and now its looking like it will be next week or maybe end of this weekend.

[sundayj]

@cpjet64 Yes, please share! I'd be happy to look it over and help out where I can.

@sundayj invites sent to both extension repos. didnt realize until tonight that theyve been public this entire time lmfao.

Just click the claude code plugin button in Pycharm, and run codex in the terminal, lol.

@EpicWatermelon Personally, I pay for Chat GPT, but I don't pay for Claude. Sure, we could use the free credits, but they wouldn't share the same context. I already use Junie through my company, but I've found that Codex is better.
Using Codex in the IDE similar to the way Junie is utilized is definitely the best case.

@sundayj i might have v1 available for testing late tonight. There's still some things I need to do like add the codex icon etc and get the licensing up to where it's supposed to be but I got a ton done last night/early am today. When I get home in about a hour I'll start working on it again if you have some free time tonight to connect in a call I want to hear your thoughts on implementation and feature set. Since the jetbrains extension is ahead of the visual studio 22 extension that is the one I'm focusing more effort on right now so I can get it out there and start having people test. Ideally once the extensions are stable I want to just pass the source and maintenance to the codex team unless they wanna hire me lol... I've also simultaneously been working on my fork bringing stability to windows clients but more on that later.

@cpjet64 Wow, sounds like you've got a lot done! I'm on the east coast USA and I'm going to be putting my kids to bed soon. I wouldn't be able to talk on a phone call, tonight, but I do plan to look at the code tonight before I go to bed.

Same here US East coast and also putting kids to bed. I'll be home in about 30 minutes take a shower put the kids to bed and then I'll make sure I push everything that hasn't been pushed yet so you can see the latest work. Jump on x.com and dm me so we can plan either a text or call sometime this week. Your input is going to be invaluable since I only use pycharm so I can't really speak to the other IDEs and what should be integrated etc. @sundayj

This would be pretty awesome, thinking of switching from Junie to Codex in PHPStorm, but CLI is just not enough comfort.

[JosepSalvat]

I have an entire team of Software Engineers waiting for this feature. Codex is the best option we've found.

[cpjet64]

@JosepSalvat making good solid progress still on the extensions. i put a hold on the vs22 extension because i had several people request jetbrains first. heres a sneak preview of the ugly ui in intellij idea. i have some of the codex integration completed and can chat back and forth with codex already. todo is already completed and functional. I am building both extensions open source if people want to help contribute. I had to take a small break from extension work to focus on my windows support for codex fork since a lot of the issues i was running into with the extensions was because of the poor windows integration. all are available on my github if you want to follow progress.

[Cris70]

I'm really interested, too! Thank you @cpjet64 !

[basserd]

I'll be following this as well, I've been using Augment Code a lot within PHPstorm. I'm now trying out OpenAI Codex, would love to use it in my IDE of choice but running it in a docker container sucks (regarding the oAuth steps). Currently using VScode, I feel like Codex has real potential.

[ValentinAUCLERC]

Very interested too, please give us some love !

@cpjet64 Interested by your solution too :)
