Cloudflare Turnstile

ELI5 — The Vibe Check

Turnstile is Cloudflare's CAPTCHA replacement that doesn't make you click on traffic lights. It runs invisible challenges in the background to verify you're human. No puzzles, no frustration — just a simple widget that says 'yep, this is a real person.' It's like a bouncer who checks your ID by reading your vibe instead of your driver's license.

Real Talk

Cloudflare Turnstile is a CAPTCHA alternative that verifies users are human without user interaction puzzles. It uses a combination of browser signals, machine learning, and proof-of-work challenges to detect bots. It's free, privacy-preserving (no tracking), and provides a widget and server-side verification API.
