See how every PSP renders checkout.
Live playgrounds for Adyen and Stripe. Flip the same configuration options a real integration exposes, and watch the checkout change as you do it. Nothing here takes a real payment.
Playgrounds
Adyen Drop-in
Every enabled payment method in one unified form. Cards, wallets, local methods and stored cards, handled together by a single component.
Open playgroundAdyen Components
Mount one method at a time and place each one yourself. Full control over layout, method selection, and how stored cards are shown and removed.
Open playgroundStripe Checkout
Stripe's prebuilt checkout, embedded on the page instead of reached by redirect. Stripe renders the form; you mint the session and handle the return.
Open playgroundPayPal Checkout
The next playground. Wallet-first checkout with its own session model and a different approach to buyer authentication.

Agentic commerce
Buying through an AI assistant instead of a website, running on a live Stripe integration. Ask for something, buy it in the panel, then read what a shop has to provide and see the requests that arrived during real checkouts.
Open pageWebhook feeds
What Adyen and Stripe send after a payment, stored and published as delivered. Two feeds, one panel, so the disagreement between the two event models is visible rather than described.
Open feedsFAQ
Questions that come up repeatedly in payment integrations, each answered on its own page rather than buried in a list.
Open FAQBuilt to test before you buy
Picking a payment provider usually means choosing one before you have ever seen it work. The checkout gets built months into the project, long after the RFP is conducted and contract is signed. It is a bit like buying a t-shirt you have never seen.
Every playground here runs the provider's own SDK against its test environment and puts the real configuration surface in front of you as plain controls. No integration, no sandbox setup, no code.
