Vibe App Scanner
Most apps built with AI tools ship with security holes their makers never see - a Supabase table anyone can read, a live API key sitting in the JavaScript bundle, no security headers at all. bleek finds them in seconds.
Paste your app's URL, and bleek runs 26 checks against it: leaked secrets, exposed databases (including the CVE-2025-48757 row-level-security class that hit a documented 10% of Lovable+Supabase apps), missing security headers, open environment files, cookie flags, TLS and email DNS. Each finding comes with a severity and a copy-paste fix written in plain English, not jargon.
The free scan needs no signup.

Less: No fancy pansy "report" Personally I prefer https://hardenize.com nowadays, over ssllabs for these kind of queries. - Source: Hacker News / over 4 years ago

There are many notable open-source projects (SSLyze, CipherScan, testssl.sh, tls-scan, …) and several SaaS solutions (CryptCheck, CypherCraft, Hardenize, ImmuniWeb, Mozilla Observatory, SSL Labs, …) to do a security setting analysis, especially when we are talking about TLS, which is the most common and popular cryptographic protocol.
