The best AI coding assistants
Autocomplete stopped being the interesting part some time ago. What separates these now is how much of a repository a tool can hold in its head, and whether it can run the tests it just broke.
Benchmarks here are easy to game, so we weight what a team can verify in a week on its own codebase over any published score.
What we look at
- Works across a whole repository, not one open file
- Runs and reads the test suite before proposing a change
- States plainly where your code is sent and how long it is kept
- Reviewable diffs rather than wholesale rewrites
- Works in the editor your team already uses
Helps if you have it: A public data-handling page naming retention and training, and a real pull request the tool opened.
