Who should pick which

Pick Cursor for developers who want an AI-first editor with agents and code review (Plus: $8/month); think twice if you want flat pricing that includes third-party models.

Pick OpenAI Codex for ChatGPT subscribers who want one coding agent across the terminal, IDE, desktop app and cloud (Go: $8/month). Watch out: usage limits depend on your ChatGPT plan; Plus and Pro users who hit them must buy extra credits. Pick Devin for teams that want to hand well-scoped tickets to an agent and review the PRs (Pro: $20/month); think twice if you want to stay hands-on in your editor, or you can't give an agent repo access. Pick OpenHands for teams that want an autonomous agent they can self-host and audit (free plan: Open source: free, unlimited local use. Cloud Individual: free, 10 conversations/day, BYOK or at-cost models); think twice if you want an inline autocomplete assistant inside your editor. Pick Graphite for GitHub teams who want stacked PRs and AI review in one workflow (Starter: $20/user/month billed annually). Watch out: unlimited AI reviews need the $40/user Team plan; GitHub only.
