# SniffPup Discussions

SniffPup is a free, passive security scanner for apps built with Lovable, Bolt, Cursor, Replit and v0. Paste a live URL and it runs about 15 checks — exposed API keys, public .env and .git files, missing security headers, Supabase and Firebase exposure — and explains the fixes in plain English. It never sends attack traffic. It also runs as a hosted MCP server for Claude Code and Cursor.
