The honest brief
Codex
Backed by OpenAI's Codex-tuned models and integrated across CLI, IDE, web, and ChatGPT — one coding agent everywhere you work.
- Local CLI, cloud, IDE, and ChatGPT
- Cloud agent runs in isolated containers
- Parallel cloud agent tasks
- Cloud agent and models are proprietary
- Best value needs a ChatGPT plan
- Token-credit billing can surprise
- Newer than rival coding agents
Cursor
Pioneered agentic, multi-file editing in a familiar VS Code fork — frontier models bundled, no API key wrangling.
- Inherits the VS Code extension ecosystem
- Frontier models bundled in one plan
- Strong multi-file agent + tab completion
- BYO key supported
- Closed source (the editor itself)
- Heavier on usage limits at higher tiers
- No first-party Linux/mobile parity gaps
