How to choose
- Decide where the AI should work — terminal, editor, browser or GitHub. That rules out half the list.
- Check model lock-in. Claude Code uses Anthropic Claude models (Opus, Sonnet, Haiku families). Bring-your-own-key tools let you change models later.
- Run one real task from your backlog in your top two picks and compare the diffs, not the marketing. Our benchmarks page shows independent agent scores where they exist.
