How to choose

  1. Try it on your real codebase, not a demo. Results vary a lot by language and project size.
  2. Decide how much control you want: suggestions you accept line by line, or an agent that makes larger changes for you to review.
  3. Check your company's rules on sending code to outside AI services before you start.
