The verdict

Rebuy wins, 8.3 to 6.1

Rebuy works with one store platform, Shopify, and starts at $25 a month, scaling with your orders. Clerk.io works with four store platforms and is priced per module from $119 a month, scaling with requests. Rebuy carries SOC 2 certification and its own Shopify App Store listing, which Clerk.io does not have; Clerk.io still connects to Shopify directly through its own script. Both give you a public API and no minimum contract term.

Pick Clerk.io if you sell on multiple platforms and want per-module pricing.

Pick Rebuy if you're Shopify only and want SOC 2 certification.
