Website Vulnerability
Scanner

Detect exposed secrets, dangerous code, missing security headers, insecure forms, and more. Every finding includes an AI prompt to fix it.

New: AI Fix Prompts. Every vulnerability includes a "Copy AI Fix Prompt" button. Paste it into Cursor, Lovable, Bolt, or any AI tool — it tells the AI exactly what to fix and how.

Passive analysis only. Only scan sites you own or have permission to test.

AI Fix Prompts

Every vulnerability includes a prompt you can paste into Cursor, Lovable, Bolt, or v0. No security knowledge needed — just copy, paste, and let the AI fix it.

02

Client + Server Scan

Two-layer analysis: client-side HTML/JS scanning plus real HTTP header inspection via our backend. Covers what both browser tools and header checkers see.

03
