Atlantic
Atlantic reads your backlog, support desk and repository, picks one problem, writes the fix, tests it in a browser, has a second model review the diff and opens the pull request.
- From tickets to pull requests
- Evidence on the pull request
Atlantic vs Codex
From delegated task to proven pull request.
Codex is OpenAI's coding agent. You or your tools hand it a task, and you review what it returns. Atlantic starts earlier, from your tickets and support desk, and opens the pull request last, after a browser test on video and a second-model review.
- Browser test on video
- Second-model review
- Auto-merge is off by default
Same repository. A different finish line.
Both can write the change. The difference is who picks the problem, how the change is proven before review, and when the pull request opens.
Codex
Codex is OpenAI's coding agent. You give it a task in ChatGPT, your editor or the terminal, or assign it an issue in Linear. You review the diff and test results, then commit or open the pull request.
- Delegated tasks
- Included in ChatGPT plans
| Feature | Atlantic | Codex |
|---|---|---|
| How work starts | Three finders read your backlog, support desk and repository, each working blind. A judge picks one problem. | You or your tools hand it a task: assign an issue or mention it in Linear, let a triage rule delegate new issues, or run scheduled tasks on a timer or on Gmail, Slack and GitHub events. |
| Browser testing | Before the pull request opens, a browser agent drives the change for up to 40 steps on a fresh preview machine, recorded on video. | In the desktop app, Codex can drive a built-in browser against your local dev server. OpenAI's docs say browser use is not yet supported in cloud tasks. |
| Review of the change | A second model reviews the diff. Blockers go back for up to 2 fix cycles before the pull request opens. | The /review command checks local changes before you commit. On GitHub, @codex review or an automatic-review setting posts a review on the pull request. |
| Where it works | Writes only to GitHub today. | Code review on GitHub is generally available. OpenAI's GitLab page says GitLab support, including merge request review, is in beta. |
| How you pay | A credit is used only when Atlantic opens a pull request. Failed and cancelled runs are free. | Included in ChatGPT plans with usage limits. Extra use draws on credits metered per token, and API keys bill at API rates. |
