AppLeakWatch
Security scanner for Base44 apps
If your Base44 app is on a domain you control, AppLeakWatch can check what it exposes to the public internet.
What usually goes wrong
Keys in browser code
Any key that reaches the browser can be copied by a visitor.
Open addresses
Addresses that answer without a login can expose customer data.
Weak browser protection
Missing security headers make common attacks easier.
What else we check
- API keys for Stripe, OpenAI, Anthropic, AWS and others in your public code
- Downloadable .env, .git and database backup files
- API addresses that return data without a login
- SPF and DMARC records that stop people faking your email
- HTTPS redirects, certificates and browser security headers
How it works
Add your domain, prove you own it with one small change, and get a report with a letter grade and every check we ran. Scans only read public addresses and never change anything. No scan can prove an app is secure, but it can find the mistakes strangers look for first.
