World-class teams use cubic

See how modern software teams use cubic to ship faster.

cubic gets us to a better review more quickly—nit-picks are gone, you can feel the velocity increase.

Marc Littlemore

Engineering Manager, n8n

cubic immediately improved our review process—PRs move faster and quality is up. Reviews are a big bottleneck, and most AI tools only help you write code.

We use cubic for Better Auth and it’s been so good. We get a lot of PRs and it helps us merge them much faster.

Bereket Engida

Founder, Better Auth

I've been a dev for 13+ years and I'm still routinely humbled by what cubic catches. We've tried other tools but cubic is way better—there’s no comparison.

Frequently asked questions

Your question not answered here? Email us.

What counts as a reviewed line?

Reviewed lines are the PR code changes cubic actually reviews, not repository size, total file size, or lines generated by AI. For most PRs, this means the added and deleted lines in the diff that cubic reads during review. Generated files, vendored code, binaries, ignored files, skipped files, and failed or cancelled reviews do not count. Incremental reviews only count newly reviewed changes; manual reruns count again.

When does usage reset?

Reviewed-line usage resets with the billing period.

Do generated or ignored files count?

No. Generated files, vendored code, binaries, and files ignored by cubic configuration do not meaningfully count toward reviewed-line usage.

What programming languages do you support?

cubic is language-agnostic and supports all popular programming languages, including JavaScript, TypeScript, Python, Go, Ruby, Java, and C#.

Do you have an open source plan?

Yes, cubic is free for public repositories. Just connect cubic to a public repository to get AI reviews.
