AI code review that understands your entire codebase.

CodeProof doesn’t just review the diff. It reads how the change reaches into the rest of the system — the callers, the contracts, the edge cases — and reviews what actually changed for your codebase, not just the lines in the pull request.

one changed file, five places CodeProof checks before it approves

The problem

AI makes developers faster.

But faster code can create harder-to-review code.

Pull requests are bigger, changes are more frequent, and the person reviewing them still has to hold the whole system in their head. Reviewers are becoming the bottleneck — not because they’re slow, but because the codebase moves faster than any one person can track.

How it works

Four steps, one continuous pass from your repository to a review you can actually trust.

Connect GitHub

Install the CodeProof app on a repository. Read access only — nothing is written until you open a pull request.

CodeProof understands your codebase

It indexes the full repository: modules, call graphs, data models, and the patterns your team already follows.

Open a PR

CodeProof reads the diff against that index instead of in isolation, tracing where the change actually reaches.

Get an evidence-backed review

Every finding links to the exact file and line it's based on, so you can verify it in seconds, not minutes.

What a review looks like

A developer adds partial refunds to the billing service. The diff looks routine. CodeProof traces it back to the payment abstraction the rest of the codebase depends on — and catches what a diff-only review would miss.

Support partial refunds on subscription invoices#482

Openjbarrett wants to merge into main from jbarrett/partial-refunds

⚠️ This change bypasses the existing payment abstraction.

ledger.write() is called directly instead of going through PaymentLedger.record(), which every other write path uses to enforce idempotency keys. A retried webhook on this path could double-write the refund.

•services/payments/ledger.ts:118 — where the idempotency key is normally applied
•services/billing/webhook_consumer.ts:76 — the retry path that can re-fire this handler

Why CodeProof

Full-codebase context

CodeProof indexes the whole repository, not just the files in the diff, so it knows what a change touches beyond the PR.

Architecture awareness

It understands the boundaries your team has drawn — services, layers, ownership — and flags changes that cross them.

Business-logic checks

Beyond syntax and style, CodeProof checks whether a change still satisfies the rules your product actually depends on.

Evidence-backed findings

Every comment links to the file and line it's based on, so you can check CodeProof's reasoning instead of trusting it blindly.

High-confidence reviews

CodeProof only speaks up when it has traced the evidence, so what lands in your PR is worth reading instead of noise to filter.

Give your codebase a reviewer that understands it.

CodeProof is in private beta with a solo engineer. We’re adding a few more each week.
