Cloudflare Turnstile is a solid CAPTCHA replacement — if you live inside Cloudflare. useHUMA gives you invisible human verification with no Cloudflare account, no vendor lock-in, plus real-time webhooks and post-login session monitoring that Turnstile doesn't offer.
| Feature | useHUMA | Cloudflare Turnstile |
|---|---|---|
| User-visible challenge | Invisible — no checkbox, no puzzle, no friction unless a borderline case triggers step-up. | Sometimes — a managed widget or interaction challenge appears. |
| Detection method | Behavioral biometrics — mouse, keyboard, scroll and touch patterns scored in real time. | Network-level signals and TLS fingerprinting tied to Cloudflare's infrastructure. |
| Privacy / PII | Zero PII — only statistical signal aggregates are stored. No ad-tech, no profiling. | Limited — Cloudflare processes your users' traffic. |
| Mobile support | Native — touch pressure, tap intervals and swipe speed captured on iOS/Android. | Partial — primarily desktop-oriented signals. |
| Integration | One API call. `npm install usehuma` with React hooks and a drop-in gate component. | Script tag widget, tied to the Cloudflare dashboard. |
| Webhooks & session monitoring | Built-in — real-time bot.detected / human.verified events and post-login anomaly detection. | Not available — verify-on-load only. |
| Vendor lock-in | None — open SDK, self-hostable verification API, runs on any stack. | High — requires a Cloudflare account and ecosystem. |
