Top Captcha Shopify Apps Ranked by Position
Captcha Guard ranks #1 for captcha with 0.7% share — the leader position in a fragmented field where many apps are within striking distance, -92.9pp ahead of Powerful Contact Form Builder (93.6%). Cart Block: checkout validator sits at #3 with 1.4% share, rounding out the top tier.

FormGuard ‑ Spam Blocker is the standout mover this month, climbing 3 positions — a momentum signal worth tracking.
