I built burner-bouncer: a zero-dependency disposable email detector for JavaScript and Python

Ever had users sign up with [email protected] or [email protected] ? Disposable email addresses are a headache for any app that relies on real user contact. I built burner-bouncer to solve this — a zero-dependency library that detects disposable/burner email domains instantly, with no API calls and no external requests. Features 🚫 629 real disposable domains blocked out of the box ⚡ Zero runtime dependencies 🟦 TypeScript-first (ESM + CJS) 🐍 Python 3.8+ support 🔁 Identical API in both
