Pros & cons

Codex CLI
Pour
  • +Zero-install terminal workflow — agent where engineers already live
  • +Open source under permissive license; auditable end-to-end
  • +Ideal for one-shot refactors, audits, and migrations
Contre
  • −No long-running session UI; not built for hour-long autonomous work
  • −Less polished than IDE-native alternatives
  • −You wire the model key + handle rate limits
Cursor Agent
Pour
  • +Best-in-class editor-native UX — agent and inline tab-complete in the same tool
  • +Lowest friction to start at $20/month
  • +Cursor itself is the most-used editor among working engineers in 2026
Contre
  • −Sessions don't survive a restart cleanly — long-running work breaks
  • −Planning horizon is shorter than Devin's
  • −Background-agent quotas can throttle on busy days
