Expert Insight: CAPTCHA & Bot Detection Services Market Share & Momentum
reCAPTCHA is under three fifths of the market, and Cloudflare's two products are taking the new installs.
Google reCAPTCHA is on about 3.6M of the 6.3M live sites where we detect a CAPTCHA or bot-management layer, roughly 58%. Cloudflare Bot Management is second at about 33%. Over the latest 30 days the net gains are almost all Cloudflare's, about 17,500 domains for Bot Management and 14,600 for Turnstile, while reCAPTCHA and hCaptcha both lost ground.
Two vendors, 90% of detections
reCAPTCHA (~58%) and Cloudflare Bot Management (~33%) dominate; Turnstile (~4.2%), hCaptcha (~2.2%) and CleanTalk (~1.1%) 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.
Cloudflare's two products are the only large gainers
Over the latest 30 days Bot Management added about 17,500 net domains and Turnstile about 14,600; nothing else gained more than about 1,300. Turnstile is the cleaner signal, up about 51,000 over 90 days on a base near 265,000. Bot Management's 90-day figure, about +298,000, runs far ahead of its monthly pace, and the row is matched on the __cf_bm cookie, which Cloudflare's free Bot Fight Mode sets too, so read it as reach rather than purchases. CleanTalk, Hu-manity.co and AWS WAF post big 90-day gains as well, each close to or above its whole footprint at our previous snapshot and almost none of it from the latest month: rules starting to fire, not adoption.
reCAPTCHA and hCaptcha carry the losses
reCAPTCHA dropped from about 303,000 sites and was added on about 102,000 in 30 days, a net loss of roughly 201,000, and it's down about 184,000 over 90 days too. That's about 8% of its base in a month against about 7% for the category, and most other categories we track fell in the same month, so read it as crawl coverage and the web's own turnover rather than sites removing a CAPTCHA. hCaptcha lost about 50,000 net over 30 days and 55,000 over 90, and our hCaptcha profile traces most of that drop to one for-sale page template going dark rather than to anyone switching.
Share is moving to Cloudflare
The direction that holds on both windows is simple: Bot Management and Turnstile up, reCAPTCHA and hCaptcha down. The category's 90-day net, about +194,000, rests mostly on Bot Management's cookie-matched figure and on rules that started firing inside the window, and the latest 30 days are down about 223,000, so neither total says much about demand. Anubis, the open-source proof-of-work challenge aimed at AI crawlers, is on about 2,900 sites once lapsed and spam domains carrying its cookie are set aside, and it's down on both windows.
