Stop punishing users with traffic lights. IronWall is a privacy-first alternative to reCAPTCHA. Instead of checking humanity, we challenge the device's computational power (Proof-of-Work). Spamming 1M requests costs a botnet real electricity/CPU time, making attacks economically unviable. ✅ 3KB SDK (Tiny) ✅ No Tracking / No Cookies ✅ Invisible to Humans (~1s solve time) ✅ Enterprise Controls (Geo-Fencing, IP Reputation) Drop-in support for React, Vue, and Vanilla JS.

Hi Product Hunt! 👋 I'm Clein, a solo founder from Nairobi 🇰🇪. I built IronWall because I was building AI apps, and bots kept draining my OpenAI credits by spamming my signup forms. I tried reCAPTCHA, but it ruined my UI and users hated clicking traffic lights. I realized: Why ask the user to prove they are human? Let's make the computer pay. IronWall uses Client-Side Proof of Work. It forces the attacker's CPU to calculate hashes before submitting data. For a human: It takes 1 second (invisible). For a botnet: It costs thousands of dollars in server time to spam you. The dashboard is fully live. The SDK is on NPM. I'd love to hear your feedback on the integration flow! ---Clein
