Best AI coding agents and AI IDEs
Coding agents read your repo, edit files and run commands; AI IDEs put that power inside your editor. This list is for people who still read the diff and want the strongest assistant for real codebases.
Ranked by score on our 100-point rubric (how we score). Scores are initial editorial estimates from public information, not hands-on tests. Pricing is labeled verified (checked on the vendor's official pricing page, with date) or unverified. Prefer the visual version? See the Coding agents tier list.
