Add support for the Dev Container specification, as most cloud development environments already do.

What Codex product are you using? Codex web?

Can you say more about your use case and the feature you want to see?

I tried Codex Web yesterday to update my .NET app from version 9 to 10, but noticed in the log that the screenshot wasn’t available because it couldn’t run due to “.NET not found.” Projects often have many different dependencies, and a single universal image might not solve this. When it comes to custom images, devcontainer support is a much better option since it’s an industry standard.

I would really love this for the Codex Mac Desktop app.

So similar to how you develop with devcontainers using VS code and its variants like Cursor.

90% of our development happens inside of dev containers. We love them because of isolation, portability, and fast requirements setup and onboarding to projects for our team.
