CAPTCHAs make every visitor prove they're human with puzzles and checkboxes — hurting conversion while modern bots solve them anyway. useHUMA is the CAPTCHA alternative that verifies real humans invisibly, using behavioral biometrics, in a single API call. No puzzles, no Cloudflare, no PII.
CAPTCHAs interrupt everyone to catch a few bots. useHUMA verifies humans invisibly from behavioral signals — no checkbox, no puzzle, no drop-off at your most important moments.
Modern bots already solve CAPTCHAs
Solver farms and headless browsers clear image puzzles cheaply. Behavioral biometrics analyze how a real person moves, types and scrolls — far harder to fake at scale.
Privacy by design
No ad-tech, no cross-site tracking, no PII. useHUMA stores only statistical signal aggregates, so you protect your forms without handing user data to a third party.
One API call, any stack
No widget lock-in and no Cloudflare requirement. Call the REST API or drop in the usehuma npm SDK with React hooks — live in minutes on any hosting.
useHUMA verifies real humans using behavioral biometrics — mouse, keyboard, scroll and touch patterns — instead of puzzles. It's invisible to legitimate users, stores no PII, and integrates with a single API call on any stack.
Can I replace CAPTCHA without showing a puzzle?
Yes. useHUMA verifies humans from behavioral signals with no visible challenge. Only genuinely borderline sessions ever see a lightweight step-up.
Is a CAPTCHA alternative more secure than reCAPTCHA?
Modern bots increasingly solve image-based CAPTCHAs like reCAPTCHA. Behavioral biometrics analyze how a real human interacts, which is significantly harder to spoof at scale, while removing user friction.
Replace CAPTCHA in one API call.
