Captcha Shopify Apps – Analytics & Insights

Captcha Guard ranks #1 for captcha with 0.8% share — the leader position in a fragmented field where many apps are within striking distance, -86.5pp ahead of Powerful Contact Form Builder (87.3%). Formful – Contact Form Builder sits at #3 with 1.4% share, rounding out the top tier. Together, the top 3 apps absorb 89.4% of all captcha installs — a highly concentrated landscape with limited room for new entrants. FormCRM AI Custom Form Builder is the standout mover this month, climbing 3 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.

Captcha is a fragmented market — the top 3 apps together hold only 89.4% of installs, leaving Captcha Guard's 0.8% lead modest in absolute terms and Formful – Contact Form Builder at 1.4% still capturing meaningful share. With this many viable apps, pricing model and integration depth differentiate captcha options more than rank does.

Together, the top 3 markets account for 47.0% of captcha app installs worldwide. Germany (7.2%) and Japan (5.0%) round out the top 5.
