Expert Insight: CAPTCHA & Bot Detection Services Market Share & Momentum

reCAPTCHA is two-thirds of the market; hCaptcha and Turnstile are taking the new installs.

Data as of 2026-08-19 · Reviewed 2026-08-15

Google reCAPTCHA is on about 3.3M of the 5.0M live sites where we detect a CAPTCHA or bot-management layer, roughly 65%. Cloudflare Bot Management is second at about 26%. But the growth over the latest 30 and 90 days is at hCaptcha (+25,000 and +27,300 net) and Cloudflare Turnstile (+7,600 and +15,600).

Market share

Two vendors, 92% of detections

reCAPTCHA (~65%) and Cloudflare Bot Management (~26%) dominate; Turnstile (~3.6%) and hCaptcha (~3.2%) are the only others above 0.5%. Enterprise bot managers (Akamai, DataDome, PerimeterX, Arkose) show in the thousands of sites, not millions: they protect high-value targets, not the long tail.

Movers

hCaptcha is the fastest-growing challenge on the web

hCaptcha added about 32,300 domains and lost 7,200 in 30 days, a net +25,000 on a base of about 161,000. Turnstile netted +7,600. Both are pitched as privacy-preserving reCAPTCHA replacements, and this is what that pitch looks like in adoption data.

Churn

reCAPTCHA turns over at 5% a month

reCAPTCHA dropped from about 175,000 sites and was added on 137,000 in 30 days (-38,200 net), then shows +13,900 over 90 days: the web's own turnover, running through the most common script on it. CleanTalk is the one vendor losing on both windows (-1,400 in 30 days, 13% of its base).

Trend

Growing and diversifying

Bot detection is up about 68,900 net over 90 days. reCAPTCHA is still growing in absolute terms but losing share to Cloudflare's two products and hCaptcha. Anubis, the open-source proof-of-work challenge aimed at AI crawlers, is at about 7,500 sites and growing (+270 over 90 days), a new sub-category worth watching.
