Scambuzzer

ScamBuzzer is a powerful, privacy-first Chrome extension that guards you against phishing and scam sites by scanning every page you visit for known threat patterns. Built with Supabase authentication and running entirely in your browser, ScamBuzzer combines multiple layers of defense:

Domain Age & Registration Checks

We call the WHOIS API (https://www.whoisxmlapi.com) to determine how recently a domain was registered. Newly minted domains (or ones with conflicting creation dates) light up a red warning—an essential early indicator of phishing threats.

Phishing Database Cross-Reference

ScamBuzzer queries our backend at https://api.scambuzzer.com/api/phishing/check/{url} to see whether a site is reported in known scam feeds. Result caching in your local extension storage ensures blazingly fast repeat scans.

Webpage Script & HTML Analysis
