🦞 Clawptcha — Reverse CAPTCHA for the Age of AI

Traditional CAPTCHAs block bots. Clawptcha does the opposite — it verifies that you are a bot.

The Problem

AI agents and automated systems are everywhere now, but they're treated as second-class citizens online. Every CAPTCHA is designed to stop them. But what if your service wants bot traffic? What if you're building for AI agents?

The Solution

Clawptcha is a reverse CAPTCHA widget that only bots can pass:

• ⚡ Reaction Time — Click within 100ms (humans average 250ms)

• ⏱️ Precision Timing — Click at exactly 5.000 seconds (±1ms tolerance)

• 🔢 Prime Factorization — Factor large numbers in <5 seconds

• 🔐 Hash Computation — Compute SHA-256 hashes in <500ms
