The QA leader your codebase never had.
Harvey checks your whole app — security, tests, performance, data, maintainability — and hands you one readiness verdict you can act on. It's the senior quality review you can't yet justify hiring for.
No database, no credentials, no production contact. Just point us at your repo.
You shipped fast. Do you actually know what you shipped?
No QA team, no senior lead reviewing every merge — just you and an assistant that says it's fine. The result is a codebase you can't see the true state of: which tests can't catch a bug, where the data's exposed, what falls over at scale.
Most founders find out the hard way. To take one example: when researchers reviewed public apps built with AI tools, roughly one in ten was exposing user data — a blind spot no one on the team could see. Shipping fast was the right call. Harvey shows you the real state of what you built — before it costs you.
A scanner gives you noise. Harvey gives you a verdict.
You could buy a security scanner, a coverage tool, a perf monitor, and a linter — and still not know if you're ready. Harvey is the senior read that runs all of it and tells you what actually matters for your app.
The whole picture
Ten dimensions in one audit — security, tests, performance, data, maintainability — rolled into a single readiness verdict, not ten disconnected dashboards.
Judgment, not alerts
Ranked by what matters for your codebase — a senior read, not four thousand linter warnings you'll ignore. Every finding comes with the fix.
We prove it, live
Where it counts, we don't just flag — we stand up a copy of your stack and prove it. A cross-tenant leak isn't a warning; it's the row we shouldn't have been able to read.
The questions a stack of tools can't answer.
| Question about your codebase | Tools | Harvey |
|---|---|---|
| Flags syntax patterns & known CVEs | ✓ | ✓ |
| Which of my tests can't actually catch a bug? | — | ✓ |
| Can one tenant read another's data? | — | ✓ proven live |
| What will fall over when traffic scales? | — | ✓ |
| Where is unprotected PII sitting? | — | ✓ |
| One verdict across the whole codebase | — | ✓ 10 modules |
| Tells me what it did not check | — | ✓ |
Keep your tools — they're good continuous hygiene. Harvey answers a different question: is this codebase actually ready?
Everything Harvey checks before you scale.
No module is the headline. The deliverable is the true state of your codebase across all ten — a readiness verdict, not a single-issue report.
Multi-tenant security
Cross-tenant isolation, RLS, auth boundaries.
Live pen-test
A real attack on a live copy of your stack.
Hotspot analysis
Where complexity and change collide.
Duplication
Copy-pasted logic that drifts out of sync.
Dead code
What's shipped but never runs.
Maintainability
Hand-rolled code with a better replacement.
Performance
N+1 queries, missing indexes, Core Web Vitals.
Test quality
Which of your tests can't actually catch a bug.
App Router boundaries
Server→client leaks, Server Action auth.
Data classification
Every piece of PII / PHI / PCI, and where it lives.

Get your readiness report
All ten modules over your source, in plain English, ranked by what matters — a read on what your code indicates, yours to keep whether or not you buy.
Go deeper
The paid audit does what source alone can't: stands up your stack and proves findings live, tests whether your tests actually catch bugs, and reviews your live database. Different depth — not more of the same.
What the free scan can't tell you.
The free scan reads your source and reports what it indicates. A whole class of findings doesn't exist until Harvey runs the deeper tiers — no amount of static analysis can surface them.
Proven cross-tenant access
Free scan: flags an RLS policy that looks like it leaks across tenants.
Harvey logs in as one tenant and pulls another's records — the actual row you should never have been able to see.
Tests that can't catch a bug
Free scan: notes which tests exist and look thin.
Harvey runs mutation testing — breaks your code on purpose and reports which tests still pass anyway.

The free scan is a real ten-module read of your source. Connected adds your live database; Full adds standing up and attacking a running copy — the only way to prove a flaw instead of flagging it.
No "book a call to hear the price."
Publishing prices is deliberate — most boutique auditors hide them behind a call. Pricing scales with your codebase size, so a weekend project and an enterprise monorepo never pay the same.

We measure your codebase size during the free scan and quote from it — generated and vendored code doesn't count. Launch pricing; for context, source-only "vibe-code" audits run $1,500–$5,000 and a traditional pentest $4,000–$12,000 regardless of app size.
Harvey tells you what it didn't check.
An unstated limitation reads as a clean bill of health. So every Harvey report carries a coverage ledger — each module, its status, and the reason if it couldn't run. No silent gaps.
Find out what's actually in your codebase.
Source-only, no credentials, yours to keep — then see what the full audit can prove that a scan can't.
