Stripe is a developer-focused online payment processing platform used by e-commerce businesses, SaaS companies, and independent developers to handle transactions, subscriptions, and financial infrastructure. The AIWebsiteDetector.com engine identifies Stripe-powered sites primarily through one script pattern, typically the presence of Stripe's JavaScript library loaded from its dedicated CDN domain, most commonly `js.stripe.com`, which is injected into pages where payment forms or checkout flows are initialized. This script tag is a highly reliable signal because Stripe's client-side SDK must be loaded directly from its own origin for security and PCI compliance reasons, meaning sites cannot self-host or proxy it without breaking functionality. Because of this architectural constraint, detection confidence is consistently high — the presence of the `js.stripe.com` script is effectively a definitive indicator that a site has integrated Stripe's payment stack. Stripe itself is a cloud-hosted, infrastructure-as-a-service platform with no self-hosted option, making every detected instance a live integration with Stripe's managed payment systems rather than a locally deployed clone.
