Stripe

Stripe is the payments infrastructure most developers think of when a product needs card processing, subscriptions, invoicing, or marketplace payouts without building the plumbing from scratch. By our assessment, its big advantage is that it turns messy payment logic into an API-first toolkit that can scale with a software business, and it has become a reference point for online checkout. The trade-off is that it expects some technical comfort and can be overkill for very simple sellers who just want a basic button and move on. In practice it feels less like a consumer app and more like a set of controls, docs, and dashboards sitting behind the scenes. Against PayPal, it is less a wallet and more an engine for companies that embed payments directly. The company is based in the United States. For teams that need flexible online payments, it is strong; for people who want the least technical route, the setup is heavier than they may want.
