What our research says

Cursor

The default choice for developers who want agentic coding inside a real editor, with cloud agents, PR review and multi-model access that large engineering orgs have already standardized on. The catch is the bill: agent-heavy use runs past plan allowances and overages are billed in arrears, so costs need active monitoring.

Pros

  • Agents work with repository-wide context, in-editor and in the cloud
  • Multi-model access includes frontier models plus in-house Composer
  • Free Hobby tier exists for trying agent workflows
  • Widely adopted in large enterprises, so tooling and docs mature fast

Cons

  • Real monthly cost is elastic once usage-based pricing kicks in
  • Pro+ and Ultra pricing is shown only through a plan selector, hurting comparability
  • Proprietary editor lock-in versus plain VS Code with extensions

OpenAI Codex

Codex is the obvious pick if you already pay for ChatGPT and want an agent that can work in your terminal or off in a cloud sandbox without a second subscription. It is less compelling if you want a polished editor-native experience or need predictable monthly spend at heavy usage.

Pros

  • The command-line agent is open source under Apache-2.0
  • Free and Go tiers let you try it before paying for a bigger plan
  • Same agent is reachable from terminal, IDE extension, desktop app and cloud tasks
  • Can sign in with a ChatGPT plan or an API key, whichever billing suits you

Cons

  • Usage limits on subscription plans vary by model, task and local versus cloud runs, so capacity is hard to predict
  • Top-tier usage requires the higher Pro plans, which start at $100/month
  • Surfaces and plan names change often, so docs and pricing pages move around

Which one fits

Choose Cursor if you need

  • Professional developers running agents on large existing codebases
  • Teams that want code review, cloud agents and editor in one subscription
  • VS Code users wanting a familiar editor with deeper AI integration

Choose OpenAI Codex if you need

  • ChatGPT subscribers who want a coding agent included in their plan
  • Developers delegating well-scoped tasks and reviewing the resulting diffs
  • Teams that want automated pull-request review in GitHub
