Interactive tool
Which agent fits your work?
- CursorYou want to see the file, accept a diff in the editor, or launch a Cursor agent through the API without staying in the window.
- CodexThe task is a terminal goal and the model you want is OpenAI’s, outside the editor.
- BothCodex implements in one worktree and Cursor reviews the interface in another. One list of “needs you”.
| Cursor | Codex | |
|---|---|---|
| Product | Editor and agents | OpenAI CLI |
| Session | Local database, CLI, Cloud | ~/.codex/sessions |
| Diff inside the IDE | Yes | No. The diff is git’s |
| Resume in doki | cursor-agent -p --resume or the API | codex exec resume |
| Model | Whichever Cursor’s plan includes | OpenAI |
| Editor has to be open | No, if you use the CLI or API | No. The session is enough |
Stay in Cursor when the file matters
If the change is judged by looking at the screen — spacing, an empty state, a line of copy — the editor shortens the loop. Cursor’s agent sees what you have open and the diff is accepted there. doki does not pull you out of that habit: when the question is “should I push?”, it shows up in the Inbox and the answer goes back to Cursor.
The API path is for not bringing the window forward. It is described in Cursor vs doki.
Hand the task to Codex when the goal is the outcome
Codex fits assignments you can describe in a sentence and check with tests or with git, not with the mouse on a component. The session stays on disk even if you close the lid, and doki resumes it when needed.
The limit is any terminal’s limit: the editor’s visual context is not there. If the work is fine interface detail, Cursor usually leads. If it is behavior, Codex competes evenly with Claude.
Running them in parallel
Give them different worktrees. Cursor can keep the app folder and Codex the API folder. Ports do not clash and each .env is a copy. When they finish, one can review the other’s diff, or you do it from doki’s verdict.
Several agents explains the shared status. There is no Cursor plugin required for Codex, or the reverse.
Accounts that do not mix
Cursor’s plan does not turn Codex on, and an OpenAI account does not open the editor. doki is an optional third piece. Installing it does not migrate chats from one side to the other.
Keys you add in Connections stay in the Mac Keychain.
Frequently asked questions
Does Cursor include Codex?
No. Cursor has its own agents, in the app, the CLI, and the cloud. Codex is OpenAI’s CLI. doki talks to both.
Can I review in Cursor what Codex wrote?
Yes. You open the branch in Cursor when you want to read the diff slowly. doki may already have told you that the Codex session finished.
Which one do I leave running overnight?
Either, ideally in a worktree and with Guard on for anything that is not reversible. On a Mac mini or a VPS the path is SSH, described in the remote machines guide.
Does doki pick the winning model?
No. You assign the work and compare the diff. doki keeps that comparison from depending on watching two windows.
