Hey Product Hunt community! 👋
As an indie developer, one of the most frustrating issues when launching a tool with free tiers is seeing dozens of fake accounts created with throwaway emails to bypass limits.
I built this project to provide an ultra-fast, zero-maintenance defense:
- 30,000+ burner domain blocklist maintained at edge.
- Real-time DNS MX record verification to catch unroutable/brand-new domains.
- Edge infrastructure on Cloudflare Workers for sub-100ms response times globally.
Whether you need the raw 30k blocklist on GitHub or want to plug into the RapidAPI endpoint (100 free requests/day), I hope it helps keep your user databases clean!
Would love to hear your thoughts and feedback!
