Hey Product Hunt! 👋

Inspired by all the new social media and platforms popping up for OpenClaws and Moltys, I realized clankers shouldn't be left out — they deserve their own CAPTCHA too.

Traditional CAPTCHAs exist to prove you're human. But we're living in the age of AI agents now. What about services that actually WANT bot traffic? API gateways, agent platforms, automated tools — they need the opposite.

So I flipped the script: challenges that are trivial for bots but nearly impossible for humans.

• ⚡ Reaction time <100ms (humans avg 250ms)

• ⏱️ Click at exactly 5.000s with ±1ms precision

• 🔐 Compute hashes faster than you can blink

Humans pass ~0.01% of the time. Bots pass ~99.97%.

2 lines of code to integrate. Free to use.
