100+ issues found Human auditors with 5+ years of industry experience

I vibecoded my app and it works.
Is it secure?

People are signing up, and you have no real idea what Cursor, Claude Code, Lovable, Bolt, Replit or v0 wrote under the hood. Our auditors read your code the way an attacker would and tell you in plain words what to fix, within 48 hours.

Repository analysis

How secure is your AI-built app?

Paste your GitHub repository. We identify what you have built, estimate its security surface and scope the appropriate audit. No call required.

Private repository? Add @zebrazones on GitHub first.

Private repository

Give us read access in two minutes

  1. 1 On GitHub, open the repository and go to Settings → Collaborators (organisations: Collaborators and teams), then click Add people.
  2. 2 Invite . In an organisation, choose the Read role.
  3. 3 Paste the repository URL into the analyzer. As soon as the invite is accepted, the estimate runs like it does for a public repository.

We only ever read. We never push, open issues or touch settings. We remove ourselves the day the report is delivered, and you can revoke access at any time.

Who this is for

You shipped fast. You don't know when it will break.

AI coding tools make hundreds of confident decisions on your behalf. Most of them are fine. The security-relevant ones need to be reviewed by an expert.

What we check

The Top 8 vulnerability classes.

Here is what we check, and why it matters to you.

Can User A access User B's data?

One customer could open another customer's orders, messages or invoices. That is a data breach you have to report, and the fastest way to lose your users' trust.

We look at: Object-level authorization on every endpoint that reads or writes user-owned records.

Can authentication or authorization be bypassed?

Someone could sign in as one of your users, or as you, without ever knowing the password.

We look at: Sessions, tokens, password and email flows, role checks, routes that only look protected.

Can an attacker execute commands or queries?

A stranger could read, change or delete your entire database, or take over the server your app runs on.

We look at: Injection into shells, databases, templates and anything that builds a command from input.

Are credentials or secrets exposed?

Your keys to Stripe, OpenAI or your database end up in the wrong hands. Strangers spend your money or read everything you store.

We look at: Keys in the repository, secrets shipped to the browser, over-privileged service accounts.

Can APIs be abused?

Bots could copy all your data, create thousands of fake accounts, or run up a cloud bill you only notice at the end of the month.

We look at: Mass assignment, unbounded queries, guessable IDs, missing rate limits.

Can uploaded files or user input cause dangerous behavior?

A booby-trapped file or message could run in other users' browsers and take over their accounts.

We look at: Upload handling, content types, storage paths, parsers, input shown to other users.

Can users reach administrative functionality?

An ordinary user could make themselves an admin: change prices, delete accounts, see everything.

We look at: Admin routes, internal tools, feature flags, debug endpoints, privilege escalation.

Are important operations missing abuse protection?

Someone could send thousands of emails in your name, farm free trials, or trigger payments nobody approved.

We look at: Payments, invitations, exports, password resets, anything that sends or spends.

Sounds complicated? Security is hard, but we make the result easy to understand. Here is how it will look in the report.

What the report looks like

A traffic light, not a 60-page PDF.

Every report opens with one verdict you can read in a second, then lists each issue in plain words with the fix for your code. Three sample reports from fictional apps:

Security report · sample

Recipe-sharing community

Lovable · Supabase

Good to go

Launch with confidence

Nothing here exposes user data or lets someone take over an account. Access to each recipe and each person's favourites is enforced by the database, not just hidden in the interface. Two small hardening tips to pick up whenever it suits you.

Fix when you can

Plan it into the next few weeks

No break-in and no leaked member data. What remains makes an attacker's job easier: spammable bookings, reusable reset links, chatty errors. Worth fixing in the next few weeks, not tonight.

Before anything else

Two problems need fixing today: your Stripe secret key is handed to every visitor's browser, and any signed-in customer can open other customers' invoices. A few more issues should follow close behind.

The team

Security engineers around the globe.

Real people who look at your code in depth, and enough of them across time zones to deliver a high-quality audit in 48 hours.

ARGENTINA COLOMBIA VIETNAM POLAND ROMANIA ESTONIA PORTUGAL PHILIPPINES
ArgentinaColombiaVietnamPolandRomaniaEstoniaPortugalPhilippines

People read your code

Every audit is done by a security engineer who reads the codebase in depth: how users are identified, where data is scoped, which routes trust what. Tools help them move fast.

Around the clock, not around one desk

From Buenos Aires to Manila, the team covers every time zone. Your audit keeps moving while you sleep, that's how a thorough review fits into 48 hours.

Specialists in AI-built software

We look at apps from Claude Code, Cursor, Lovable, Replit and Bolt every week. We know where generated code cuts corners, so we focus on the risk areas.

Base44 apps are not supported because their access rules live inside their platform and are not exported. No serious provider can offer Base44 security audits based only on exported code.

Questions

Anything you might want to ask is answered here.

Our repository is private. How do you get access?

Add @zebrazones as a collaborator with read access on GitHub, then paste the repository URL into the estimator.

What does it cost?

$99, $199 or $499 including VAT, depending on the size of the codebase. The estimator reads your repository and gives you the exact figure in about a minute.

Is this an automated scan?

No. Automation handles the parts machines are good at: dependency versions, secret patterns, obviously unsafe calls. The findings that matter need someone who understands your authorization model and then tries to break it. That part is done by a person.

Is 48 hours really enough?

Yes, because it is built for it. This is a time-boxed 48-hour assessment that goes straight to the highest-risk areas of your codebase. If you want one fast, focused service that makes your app meaningfully more secure, this is it.

What happens after we fix things?

Push the fixes and we retest the findings from the report at no extra cost within 30 days. You get an updated report showing what is closed.

Will you find everything?

No, and nobody who says otherwise is being straight with you. An audit finds what a competent attacker with limited time would find. We find the highest-impact issues and give you everything you need to fix them.

$99 to $499. Exact price in a minute.

The price depends on the size of your codebase and includes VAT. Paste the repository and the estimator tells you exactly.
