You built an app with AI. Before your users find the problems, we check it in five areas, test your key user flows and give you a fixed price for the fixes.
Who it's for
What you get
Security, key user flows, speed, SEO and AI visibility, launch readiness. Each area gets a clear rating: OK, needs work or critical.
We cover 3–5 key user flows, such as sign-up, login, payment and your main action, with automated tests (Playwright). You get them as a pull request or a package for your repository, so you can rerun them after every AI change.
The report lists fixes by priority, with a fixed price and deadline. Fix it yourself, with your team or with us. No hourly billing.
Login and sessions, data access rules (such as Supabase RLS or Firebase Security Rules), keys and secrets exposed in the browser, API endpoints that return other users' data, vulnerable dependencies, security headers, file uploads and rate limits.
3–5 key user flows tested with automated tests on a staging copy.
Core Web Vitals from real users (Google data, when available) and Google Lighthouse tests, bundle size, images and how fast the app responds to taps and clicks (INP).
Content visible without JavaScript (server rendering or prerendering), titles and descriptions, sitemap, robots.txt, basic structured data, and access for search and AI bots.
Environments and environment variables, error reporting, backups, uptime monitoring, domain and SSL, email setup (SPF, DKIM, DMARC), and whether privacy and cookie policies are in place (we don't review them legally).

How we work
Send the form or an email: what the app does, which tool you built it with and the 3–5 flows that matter most. We confirm scope, price and start date by email.
Read access to the code, a staging copy with test accounts and test data, and read-only access to your database and service settings. We sign an NDA and a data processing agreement (DPA) first. The 5 business days start when we have access.
We check five areas and write tests for your key flows. You get a PDF report with ratings, a prioritized fix list and a fixed-price quote.
A 15–20 minute video walks you through the report, and you can ask questions by email for 7 days. Then you decide: fix it yourself, order the fixes or add monthly care.

kontakt@fastweblab.pl$590 for an app with up to about 15 screens, one database and one login system. For bigger apps, we quote after a short description, before you pay.
Read access to the code, a staging copy with test accounts and test data, and read-only access to your database and service settings. We check settings and access rules, not your users' data. We sign a data processing agreement (DPA) before we get access.
No. We check defined areas and report the results. For a full penetration test or a compliance audit such as SOC 2, we can point you to a specialist firm.
Not by default. We work on a staging copy. We test production only with your written consent, using test accounts, and we don't copy your users' data. If a test shows other users' data, we stop and tell you right away.
We tell you right away, without waiting for the report, so you can act. Critical issues come first in the fix list.
Yes. The report describes each issue and its fix, in priority order. Your team or your AI tool can work from it. If you prefer, we fix it at the fixed price from the report.
The fixes from the report: for example access rules, login, payments, secrets, a separate test environment, speed, SEO and tests of key flows. Fixes start at $1,500, and the fixed price is in your report before any work. We work on staging first, then release to production with you, and re-test your key flows. Our fixes come with a 30‑day warranty from delivery: if something breaks because of our changes, we fix it at no cost. Later changes, including ones made by your AI tool, aren't covered.
$490 a month for an app up to about 15 screens (bigger apps: quote), starting after the review. An expert reviews up to 10 AI-made changes a month before they go live, within 2 business days. It also includes uptime, error and speed monitoring, plus a monthly report. Month to month, with one month's notice.
No one can honestly guarantee that. We guarantee the scope: every check from the review, done and reported. The report shows what we found on the day of the review.
We use it only for your project and work on it in an isolated virtual machine. We use AI tools only on business accounts with a data processing agreement, and their terms don't allow training AI models on your code. We delete our copies within 30 days after the work ends.
The review is paid upfront, by invoice in USD. Fixes: 50% to start, 50% on delivery. Care: monthly, in advance.
