Cloudflare Turnstile vs reCAPTCHA: what's the difference?

Cloudflare Turnstile and Google reCAPTCHA both stop bots on forms. Turnstile runs mostly invisible browser challenges and never shows image puzzles; reCAPTCHA v2 shows a checkbox and image grids when unsure, and v3 scores requests silently. In the directory flows we recorded, Turnstile appeared on 35 and reCAPTCHA on 21.

For submission agents

Both pass more often in a person's everyday browser than in server-run headless browsers. When either demands interaction, a responsible agent pauses for the user.

Example

A directory switches from reCAPTCHA v2 to Turnstile. Its submission completion rate rises, and image challenges disappear for most visitors.

For site owners choosing one

Turnstile suits sites wanting the least friction and no image puzzles. reCAPTCHA v3 suits sites that want a risk score to make their own decisions, such as asking for extra verification only on low scores. Either way, test the form with privacy extensions and on mobile.
