Your AI reviewer reads diffs.
This one runs the code.

Senior devs burn hours reviewing PRs that break on staging anyway

AI review tools comment "consider error handling" without understanding runtime impact

Security issues slip through because nobody runs pip-audit on every PR

Codeproof clones your PR, runs your tests, checks for vulnerabilities, and posts a structured verdict — before a human spends a minute on review.

  codeproof review — PR #47: Refactor auth middleware
✓ APPROVE

Runtime verification
  Complexity: +4% (threshold: 15%) ✓
  Coverage: 82% → 84% ✓
  Tests: 47/47 passed ✓

Security
  CVEs: 0 found
  Secrets: 0 detected

Inline
  middleware.py:42 — Unused import (os)
  middleware.py:87 — Good: retry handles TimeoutError

Why this matters
  The unused import adds no risk, but the retry
  logic is a real improvement — previous version
  would crash on network timeout during auth.
How it works
Connect one repo. See the difference.
01

Connect

Point Codeproof at one Python repo. 20-minute setup with founder support.

02

Verify

On every PR: clone, run tests, measure fitness delta, scan for CVEs and secrets.

03

Review

Get a structured verdict in your PR with evidence, not opinions. Humans review only what matters.

Security & privacy
Your code stays yours.
Where does my code run?
In an ephemeral container created for each review. The container is destroyed after the review completes. We don't have a persistent copy of your codebase.
What is stored?
Only the review output (verdict, metrics, annotations). Your source code is never stored, logged, or persisted.
Is my code sent to external LLMs?
The diff (not the full codebase) is sent to LLM providers (Anthropic, OpenAI, Google) for review analysis. Only the changed code is transmitted. If this is a blocker, we can discuss alternatives during setup.
What we don't promise yet
We're in private beta. We don't yet have SOC2, GDPR certification, or on-prem deployment. We're honest about our stage. If you need enterprise compliance, we're not ready — but we're building toward it.
Who this is for
Small Python teams where PR review is a bottleneck.

You're the tech lead who reviews most PRs yourself. Your team ships 5+ PRs a week. You've tried AI review tools that generate noise. You want to catch runtime issues and security problems before a human wastes time — not after merge.

If that's you, we'd like to set up Codeproof on one of your repos and show you the difference in 20 minutes.
