Your AI-built app might be leaking user data. Find out in 24h, free.
AI agents ship fast and leave doors open: Supabase tables anyone can read because Row Level Security is off, secret keys in the JavaScript bundle, open CORS with credentials, unverified Stripe webhooks, and login redirects pointing to preview domains. I check your live app and send you exact fix steps.

What I check
The security holes AI agents leave behind most often. The free audit looks at your live app from the outside, read-only, the way any visitor could.
Free security audit · from the outside
- Secrets in the JS bundle: OpenAI, Stripe or Supabase
service_rolekeys shipped to every visitor's browser. - Exposed Supabase data: signs that tables are reachable with the public anon key because Row Level Security is off.
- Open CORS with credentials: any website able to call your API as your logged-in users.
- Auth redirects to preview domains: login and reset links that send users to a dev or preview URL.
- Transport and headers: HTTPS redirects, Content Security Policy, Stripe test keys left in production.
Ship-Ready Security Review · $199 · inside your code
- Row Level Security, table by table: who can read and write what in your database.
- Stripe webhooks: signature verification, so nobody can fake a "payment succeeded".
- Access control: users opening other users' records by changing an ID.
- Secrets and costs: keys in source, unbounded AI calls, no rate limits.
- Data and deployment: backups, dev and prod sharing a database, error tracking.
Real case, anonymized: a hobby app built with Replit Agent let any website use its visitors' logins through open CORS with credentials. The fix was one Agent prompt. Read the case study →
Not theoretical: in 2025, missing Row Level Security in apps generated by Lovable was published as CVE-2025-48757, rated critical (9.3). Lovable disputes it, saying each app owner is responsible for protecting their data, which is exactly why it is worth checking yours.
Read-only and passive: I never log in as your users, never submit forms, never change anything and never use a key I find. Get my free security audit →

Snapforge Lab is just me. You work directly with the person who builds, reviews and ships your app, not an account manager. I build with Replit Agent every day, so I know exactly where AI-built apps break in production.

Replit app development FAQ
Is the free security audit safe for my app?
Yes. The free audit is read-only: I only look at what your live app already shows any visitor (its pages, JavaScript files, headers and API responses). I never log in as your users, never submit forms, never change anything and never touch your data. If I find a leaked key, I tell you where it is, redacted, and never use it.
How much does a custom business app on Replit cost?
A Starter Build is a flat $2,500 for a defined app (dashboard, CRM, portal, automation or AI assistant). My next 3 founding clients pay $1,500 in exchange for a short case study. Larger scopes get a written fixed-price quote within 48 hours. No hourly billing.
How fast can my app be live?
Most Starter builds go live in about 7 days after I receive access to your data. Custom scopes come with a dated timeline before you pay anything.
Do I own the code?
Yes. The app lives on your own Replit account. It is standard code you can export, and it keeps running if you stop working with me.
Do I need a Replit account?
Yes, the app is deployed on your Replit account so you keep full ownership. I handle setup, deployment and configuration for you.
I already built an app with Replit Agent. Can you make it production-ready?
Yes. The Ship-Ready Security Review ($199) audits security, data, authentication, performance and deployment, and delivers a prioritized fix list within 48 hours. If I find fewer than 3 real issues, you get a full refund. Want me to fix everything? The Ship-It Sprint ($990) does it in 5 days, and the review fee is credited.
How do payments work?
The $49 Deploy Fix and the review are paid upfront via PayPal and covered by a refund guarantee. Sprints and builds are paid half at the start and half when your app is live in production. The first month of Care is included with every Sprint and Build; after that it is $249/month and you can cancel anytime.
Do you work with clients outside the US?
Yes. I work fully async and remote with clients worldwide, in English, with written updates.
