In July 2025, Wiz Research found that anyone who knew a Base44 app's ID could register an account on it, even when the app was set to private. Base44 fixed it within a day of the report. That bug was the platform's. The ones that remain are mostly in what gets generated on top of it: an admin page hidden in the frontend while the backend function behind it answers anyone.
Base44 is genuinely fast. The platform generates working full-stack apps from plain English descriptions. But "working" and "secure" are different standards, and the gap between them is where most Base44 apps get into trouble.
TL;DR
Base44 is a legitimate AI app builder with solid infrastructure. The security risk is in the generated code, not the platform itself. Three gaps to check in every Base44 app: backend functions and entities that skip server-side auth, permissions or service-role calls that let anyone read data, and no rate limiting on public-facing endpoints. All three are fixable in an afternoon, and Base44's free security scan catches part of the first two.
What Base44 Controls
Base44 manages the infrastructure. Your app deploys to Base44's own hosting (your-app.base44.app), SSL is included, and the platform handles scaling and availability. You don't configure servers, manage certificates, or patch an OS.
That layer is fine. The problems are a level up: in the JavaScript and API code the AI generates.
What Base44 Generates (And Where It Falls Short)
Base44 produces a React frontend, entities (its database tables) and backend functions that run on Deno. The frontend handles display logic. The backend handles data. The problem is how they connect.
When you ask Base44 to "add an admin dashboard that only logged-in admins can see," it will typically:
- Add a frontend route guard that hides the page from non-admin users
- Generate the API routes to fetch admin data
- Forget to add the auth check in the API route itself
The frontend guard is real protection against casual visitors. It is not protection against someone making a direct fetch() call to your API. Anyone who opens DevTools, sees the API URL in a network request, and hits it directly bypasses your frontend entirely.
Frontend-only authentication is not authentication. A hidden page and a protected route are different things. An API route that doesn't validate the caller's identity on the server is publicly accessible, regardless of what your frontend does.
Three Gaps to Audit Before You Launch
1. Unprotected API routes
Open your app in a browser. Open DevTools (F12), go to the Network tab, and click through your app. For every API call that returns sensitive data, copy the request URL and the headers.
Paste that URL into a new browser tab with no cookies. If you get data back, the route is public.
The fix depends on what's behind the URL. For an entity, tighten its row-level security rules so the "All Users" rule ("Anyone can perform this action, even without signing in") isn't on anything private. For a backend function, add an auth check at the top of the handler before touching any data.
2. Service-role calls and keys in client bundles
Base44 backend functions can call the SDK as asServiceRole, which Base44's docs say "bypasses both RLS and FLS entirely". If the AI reached for it to make a permission error go away, the access rules you set don't apply in that function. Third-party API keys are the other leak: they belong in backend function secrets, but generated React code sometimes puts them in the frontend, where anyone can read them from your JavaScript bundle.
In your browser, open DevTools > Sources and search (Ctrl+F) for apiKey, sk_, or secret. If you find a service credential in the source code, it's in the bundle. Every visitor has it.
Then search your backend functions for asServiceRole. Every hit is a place where your entity permissions are switched off, so each one needs its own check of who is calling.
3. No rate limiting on public endpoints
AI-generated form handlers rarely include rate limiting. A contact form that accepts POST requests without any throttle will accept 1,000 requests per second just as happily as one per hour. This matters for:
- Account registration forms (account enumeration)
- Login endpoints (credential stuffing)
- Any form that sends an email (spam relay)
Add rate limiting at the function level or use a service-level rate limit from your hosting provider before you launch.
How to Audit a Base44 App in 30 Minutes
List every API route your app calls. DevTools Network tab while you click through every screen. Write down each URL and whether the response includes user data.
Test each route without auth. Open a private/incognito window and hit each API URL directly. Any that return data are public.
Search your bundle for secrets. DevTools Sources panel, Ctrl+F for key, secret, anon, service_role. Find them before someone else does.
Run Base44's security scan, then an outside one. Base44's built-in scan runs on every plan and checks data permissions, exposed secrets, and functions anyone can run. CheckYourVibe checks your deployed app for missing security headers, exposed credential patterns, and open endpoints in under two minutes.
The Verdict
Base44 is not unsafe as a platform. It is a fast way to build apps, and fast app building requires active security review. The generated code is a starting point, not a finished product. If you ship a Base44 app without walking through these four steps, you are almost certainly shipping with at least one of these gaps open.

Every AI builder has this problem. Base44 is not unique in generating apps that skip server-side auth. It is just the newest platform that founders are using to ship quickly, which means it is the newest source of apps that go live before they're audited.
Is Base44 safe for production?
Base44's infrastructure is solid, but the generated code needs review before you ship to real users. The most common gaps are unprotected API routes, client-side exposure of service keys, and no input validation on form endpoints. These are fixable but require active attention.
Does Base44 expose my data publicly?
Not by default, but the generated code can. If an AI-generated API route lacks an auth check, anyone with the URL can read or write your data. You need to audit every route in your app before going live.
Does Base44 store my data securely?
Base44 handles infrastructure security (HTTPS, isolated deployments, access controls). Your responsibility is the application layer: which data each user can see, which routes require login, and what gets stored in the database.
How is Base44 different from Lovable or Bolt?
All three generate full-stack code from prompts. Base44 keeps you in its own hosted environment with a managed backend. The security gap pattern is similar across all AI builders: fast generation, weak auth scaffolding by default.
How do I check if my Base44 app is secure?
Open your app's network tab in DevTools and look at every API request. Check which ones return data without an Authorization header. Run a free scan at CheckYourVibe to catch missing headers, exposed keys, and open endpoints automatically.
