Verify real humans in seconds.
HumanCheck is 50-100x cheaper than traditional verification. Anonymous. Frictionless. Built for platforms.
Cheaper than KYC
To verify
Government ID required
Check, recognized everywhere
The Problem
Every verification tool today
forces a trade-off.
Privacy, security, cost. Every verification tool makes you pick two. HumanCheck is the first that doesn't.
KYC collects too much
Government IDs, selfies, personal data. Traditional verification creates a honeypot of sensitive information, costs $2-$10 per check, and creates massive friction that kills conversion.
CAPTCHAs are losing the arms race
AI solves CAPTCHAs faster and more accurately than humans. You are annoying real users while bots sail through. The fundamental approach is broken.
SMS proves phone access, not humanness
Virtual numbers cost pennies. A single person can generate hundreds of phone numbers. SMS verification proves someone has a SIM card, not that they are a real, unique human.
Three steps to verified humanness
No documents. No government ID. Just proof that a real person is on the other side.
Quick camera check
User completes a brief liveness check. Takes about 15 seconds.
HumanProof confirms humanness
Our system verifies the user is a real, live, unique person and issues a cryptographic proof of humanness.
Access unlocked
The platform receives a verified human token. The user gets access.

Built for privacy. Engineered for speed.
Anonymous by Architecture
Proving you are human never requires proving who you are. No government IDs, no documents, no identity files. Privacy is not a feature we added. It is a constraint we built around.
- Verification produces a cryptographic proof, not an identity file
- No biometric templates retained
- GDPR and CCPA compliant by design
Sybil Resistant at Scale
One person, one proof. HumanCheck prevents the same individual from creating multiple verified identities across your platform. Our cryptographic approach makes multi-accounting economically and technically infeasible, whether you have 1,000 users or 10 million.
- Cryptographic uniqueness enforcement
- Cross-platform deduplication
- Scales to millions of verifications
50-100x Cheaper Than KYC
Traditional identity verification costs $2-$10 per check and takes minutes. HumanCheck verifies humanness in seconds at pennies per check. Usage-based pricing means you pay for what you use, with a free tier for developers getting started.
- Pennies per verification
- No setup fees or minimums
- Free tier for developers
We built HumanCheck because the internet needs a way to prove you are a real person without proving who you are. Privacy and security are not trade-offs. They are both requirements.

How HumanCheck stacks up
HumanCheck is not a replacement for your entire security stack. It is the missing layer that proves the human behind the account is real.
| Feature | HumanCheck | KYC | CAPTCHA | SMS / MFA |
|---|---|---|---|---|
| Proves humanness | ||||
| Prevents multi-accounting | ||||
| No government ID required | ||||
| Sub-30-second flow | ||||
| Bot resistant (2025+) | ||||
| Cost per check | Pennies | $2-$10 | Free | $0.01-$0.05 |
| User friction | Low | High | Medium | Medium |
HumanCheck works alongside your existing security stack. Pair it with MFA, rate limiting, and fraud detection for defense in depth.
Built for platforms that need real humans
Eliminate duplicate respondents. Get real human insights.
Survey fraud wastes billions annually. Bots, duplicates, and professional respondents corrupt data quality. HumanCheck proves every respondent is a real, unique person without government IDs or invasive verification, so your panel stays clean and your insights stay valid.
