AI-Generated Review

What is throwaway?

Throwaway is a TypeScript Cloudflare Worker delivering a JSON API to flag disposable email domains and invalid TLDs. Feed it emails or domains via GET/POST /check—single checks or batches up to 1000—and get back verdicts like "disposable: true" or "valid_tld: false", plus a web UI at root and /stats for filter info. It solves signup spam by blocking throwaway accounts without external API calls, all on Cloudflare Workers free tier.

Why is it gaining traction?

Ultra-fast edge checks hit microseconds thanks to compact in-memory storage of 72K+ domains, zero false negatives, and full CORS/security headers for easy frontend integration. One-click deploys from GitHub via Cloudflare Workers button work seamlessly with custom domains, GitHub actions, or OAuth logins, staying under Workers limits and free tier quotas—no AI pricing or KV overhead. Devs dig the self-hosted alternative to paid validators.

Who should use this?

SaaS builders blocking throwaway accounts on user registration forms, backend teams piping email validation into Cloudflare Workers pipelines or GitHub-hosted apps, and Home Assistant tinkerers scripting against disposables. Perfect for anyone ditching third-party services amid reddit rants on throwaway account abuse.

Verdict

Strong docs, full test coverage, and live demo make it deploy-ready despite 13 stars and 1.0% credibility—early but reliable for Cloudflare shops. Fork it if you need disposable checks without the bloat.
