Devin vs OpenAI Codex
Both are in our Coding agents tier list: Devin is A-tier and OpenAI Codex is S-tier.
| Field | Devin | OpenAI Codex |
|---|---|---|
| Tier | A | S |
| Why this tier | It is good for assign-and-forget tickets because it works on its own, in the cloud or on your machine, and tests in its own browser. You get less hands-on control than with terminal agents, which keeps it below the S-tier agents. | It sits on par with Claude Code at the top of the coding-agent list. It runs as an open-source CLI, an IDE extension and cloud tasks. If you already pay for ChatGPT, it is the natural first pick. |
