Under construction · early access opening soon
Code review that reads the whole codebase.
Difflyn is an AI reviewer for GitHub and GitLab. It reviews every pull request with the context of your entire repository, then leaves clear inline comments with suggested fixes.
src/billing/invoice.ts+1 −1
const total = items.reduce((sum, i) => sum + i.price, 0);
- if (user.plan == "pro") applyDiscount(total);
+ if (user.plan === "pro") applyDiscount(total);
Whole-codebase context
Reviews look beyond the diff to the code it touches, so findings reflect how your system actually fits together.
Your standards, enforced
Correctness, security, performance and architecture, checked against your own repository rules and conventions.
GitHub, GitLab, any model
Works on pull and merge requests where your team already reviews, with your choice of LLM provider.

applyDiscountreturns a new total, but the result is discarded here, so Pro customers are still charged full price. The same pattern appears incheckout.ts:42.
