As answered by people managing SniffPup and Socket.
SniffPup's answer
SniffPup is made for people shipping apps built with AI builders such as Lovable, Bolt, Cursor, Replit and v0, often with Supabase or Firebase backends, who want a quick outside check of their live web app's public URL.
SniffPup's answer
SniffPup is a passive, read-only outside security scan of a live web app's public URL. The free scan needs no signup, and it never logs in, sends attack payloads, or uses a key it finds. It checks for leaked API keys and secrets in page HTML and JS bundles, publicly reachable .env and .git files, public source maps, security headers and cookie flags, HTTPS/TLS, CORS, email DNS (SPF/DMARC), and whether Supabase or Firebase lets an anonymous visitor read data. It also gives copy-paste fix prompts for AI builders, and critical fixes are free. It is not a pen test or code audit.
SniffPup's answer
SniffPup's free scan needs no signup, is passive and read-only, and critical fixes are free. It includes copy-paste fix prompts for AI builders. Only scan sites you own or are authorized to test.
SniffPup's answer
SniffPup is made by Ember and Saru LLC in Charlotte, NC, USA. It is named after Ember, the founder's black Pomeranian.
