Braintree

Braintree (strategically acquired by the massive global payment titan PayPal) is a highly respected, deeply robust enterprise payment gateway that powers massive tech companies and global platforms (like Airbnb and GitHub). It competes directly with Stripe for the developer-focused market, providing a highly elegant API and robust infrastructure. However, its absolute, unbeatable superpower is its native, flawless integration with the massive global PayPal consumer network. Because it is owned by PayPal, Braintree is the absolute best platform in the world for merchants who want to offer PayPal and Venmo (in the US) as payment options alongside standard credit cards and Apple/Google Pay. When an enterprise integrates the Braintree SDK, they instantly gain access to hundreds of millions of active PayPal and Venmo users. Customers can check out with a single click using their trusted PayPal account, drastically reducing checkout friction and massively increasing conversion rates, especially on mobile devices. Furthermore, Braintree is renowned for its highly advanced "Vault" technology, which securely tokenizes and stores customer credit cards, completely removing the enterprise from the massive regulatory burden of PCI compliance. It handles complex recurring billing and global payouts efficiently. For massive global merchants where maximizing consumer conversion rates via PayPal and Venmo is a highly strategic priority, Braintree is a phenomenally powerful engine.
