Every option in the catalog for when you need to get a reviewer on every pull request automatically — 7 AI code review tools, 4 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 7 of them, ordered free tiers first: PR-Agent, CodeRabbit, Greptile, Sourcery and Qodo. 4 of the 7 are free or have a free tier. Each entry states what it uniquely does rather than a score.
1 on this page are marked fully free with no paid plan at all: PR-Agent. The remaining 6 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
CodeRabbit, Greptile and Sourcery all work in a browser tab with no install needed — just open the site and go. 3 of the 4 free AI code review tools listed here are browser-based.
Greptile supports Google sign-in, so you can start without creating a new account. That's 1 of the 4 free AI code review tools on this page.
PR-Agent can be self-hosted or run locally without a browser — useful for privacy, air-gapped networks, or avoiding API rate limits. 1 of the 4 free AI code review tools here run offline.
