They probably are, or at least will! But for now it seems like the first version that works end to end and it certainly feels like it’s a standard VM spinning up a Docker image. There are lots of more specialized solutions out there like CodeSandbox SDK which lets you prepare a devcontainer that can fork and spin up for a new PR in less than a second. So if it’s not Codex, _someone_ will nail this experience. Cursor’s new background agents could be it though I don’t enjoy them currently. And I also get the feeling they too spin up cloud VMs “the old school way”.
