Which tool reviews my pull requests automatically?

Ranked by evidence — GitHub stars, Hacker News mentions, release activity and how much you can use for free. Recomputed nightly. How the score works.
+ Tab autocomplete predicts multi-line edits across files better than any competitor.
− Usage-based pricing changes and request limits on Pro have repeatedly frustrated heavy users.
+ Deepest GitHub integration: assign an issue to Copilot and it opens a PR.
− Completions and agent lag behind Cursor and Claude Code in quality despite more models being offered.
+ Reviews are context-aware across the repo and learn from your replies to comments.
− Can be noisy, posting many nitpicks per PR until you tune the config.
+ Diamond reviews fit naturally into stacked diffs, which keeps each review small.
− Most value requires adopting the whole stacked-PR workflow.
+ Full-repo graph index lets it spot breakage in files the PR never touched.
− No free tier for private repos and comments can be verbose.
+ Long track record on Python refactoring, with rule-based suggestions that stay deterministic.
− Less thorough on large multi-language PRs than CodeRabbit or Greptile.
+ The underlying PR-Agent is open source and self-hostable with your own model.
− Several overlapping products make the offering confusing to adopt.
