OpenAI Codex Cloud alternatives in 2026
The Codex Cloud alternatives are Codex itself on a Prized box, which keeps its disk between tasks, works with any git host and runs with your laptop closed on your own ChatGPT plan, or another cloud agent: Claude Code on the web, Cursor Cloud Agents, GitHub Copilot’s cloud agent, Devin or OpenHands. Codex Cloud runs each task in a VM OpenAI manages, from your GitHub repositories, on ChatGPT Plus and up (OpenAI). It’s the simpler choice when the code is on GitHub and each task can start clean.
Pick one
- Keep Codex, on a machine that stays on: a Prized box. Codex comes preinstalled, works in a session that outlives your connection, and what it installs and builds stays for the next task.
- Assign a GitHub issue, get a pull request: GitHub Copilot’s cloud agent, which can also hand the task to Codex (preview).
- Claude instead of Codex, on your Claude plan: Claude Code on the web.
- GitLab, Bitbucket or Azure DevOps: Cursor Cloud Agents, Devin for the first two, or Codex on a box for any of them.
- Open source, on your own machines: OpenHands.
Side by side
| Where the agent runs | Git hosts | Opens the pull request | Cheapest plan with it | |
|---|---|---|---|---|
| Codex Cloud | A VM per task, run by OpenAI | GitHub; GitLab merge requests in beta | You open it after review | ChatGPT Plus, $20 |
| Codex on a Prized box | Your box, kept between tasks | Any git remote | Yes, through gh (GitHub) | $0.137 an hour (Small), plus ChatGPT Plus or an API key |
| Claude Code on the web | A VM per session, run by Anthropic | GitHub | Yes, with Create PR | Claude Pro, $20 |
| Cursor Cloud Agents | A VM run by Cursor | GitHub, GitLab, Bitbucket, Azure | Yes | Cursor Premium, $30 |
| GitHub Copilot cloud agent | A GitHub cloud sandbox | GitHub | Yes | Copilot Pro, $10 |
| Devin | A VM run by Devin, or yours | GitHub, GitLab, Bitbucket | Yes | Devin Pro, $20 |
| OpenHands | Your machine, or its cloud | GitHub, GitLab, Bitbucket | Yes | Free to self-host (MIT) |
A Small box (4 vCPU, 16 GB) is the size of a Codex Cloud task VM on Pro. Asleep, it bills only its disk, $0.030 an hour (Pricing). Codex on the box uses your ChatGPT plan’s usage, as it does on your laptop.
Move Codex to a box
Sign up: the tour starts a box on $30 of free credit, with no card, and shows one command that installs the CLI and signs it in; the plain installer is curl -fsSL https://prized.dev/install.sh | sh (Quickstart). Then, in your project folder:
cd ~/code/myprojectprized setup --sync --agent codex --attachSetup syncs the folder with the box both ways, signs Codex in there with a ChatGPT sign-in of its own, and opens Codex in a tmux session that keeps working when you close the lid. Set its approvals before you go, since a question waits until you’re back (Run Codex in the cloud).
Common questions
Can I use my ChatGPT plan with Codex on my own machine?
Yes, from Plus up: the Codex CLI signs in with your ChatGPT account and uses your plan; Free and Go get Codex in the desktop app only (OpenAI). Each machine needs a sign-in of its own, and prized setup makes the box’s.
Does Codex keep working with my laptop closed?
In Codex Cloud, and in the Codex CLI on a machine that stays on, like a Prized box. The CLI on your laptop stops when it sleeps, and so does the ChatGPT app’s remote access to it (OpenAI).
Does Codex Cloud work with GitLab or Bitbucket?
Its environments are built from GitHub repositories (OpenAI). On GitLab, Codex reviews and works on merge requests in a beta (OpenAI), and Bitbucket isn’t listed. On a box, Codex runs git as you would, against any remote.
Is a box cheaper than Codex Cloud?
No: Codex Cloud costs nothing beyond your ChatGPT plan, and a box adds its hourly price. What the box buys is a machine of your own, with any git host, a disk that keeps what Codex installed, and no limit on how long it runs.
What about Google Jules?
Google is shutting Jules down: November 11, 2026 is the last day for sessions, it is read-only after that, and it shuts down on December 31 (Google). More on where its users go: Google Jules alternatives.
