It's a split decision.
Braintree fits teams that want a sandbox, mobile SDKs, PayPal and Venmo support, and published standard US transaction rates. Adyen fits businesses that need payments, payouts, data insights and embedded financial products through one API, with a platform positioned for enterprise scale. For developers, the choice depends on payment coverage and pricing visibility versus a broader payments stack. Confirm SDK languages, API details and data-export terms with either vendor before committing.

02Pricing at real usage
Neither provider lists a free processing plan. Braintree offers a sandbox for trying its API before production; that is a testing environment, not a free transaction tier. Its Standard plan has no monthly fee and charges 2.89% + $0.29 for US cards and third-party wallets, 3.49% + $0.49 for Venmo, or 0.75% for standard ACH direct debit, capped at $5. Adyen also lists no setup or monthly fee: its transaction price starts with a $0.13 fixed processing fee plus a payment-method fee. Some methods use Interchange++ plus 0.60%. At volume, both bills grow with transaction count and payment mix, not seats or compute. Braintree lists additional fees for non-USD and international cards, chargebacks and other services. Adyen says a minimum invoice may apply to some businesses; the amount is not published.
03API, SDKs and integration
Braintree provides developer documentation and an API sandbox for trying the integration before production. Its stated coverage includes mobile SDKs, global currency acceptance and ready-built checkout interfaces; the named payment options include PayPal, Venmo in the US, cards, Apple Pay, Google Pay and local methods. The vendor does not name SDK languages or an API protocol on the vendor's site, so confirm those details against your application stack. Adyen describes a single API for multiple use cases and channels, covering payment acceptance, payouts and embedded financial products. Its homepage does not name SDK languages, a CLI or third-party integrations. Both describe payment-data or payment operations spanning more than checkout: Braintree can share payment data with other service providers, while Adyen groups payment data insights and financial products on its platform. Ask each vendor about SDK coverage, webhook behavior and migration requirements before implementation.
04Open source, self-hosting and lock-in
Braintree and Adyen are payment-processing platforms, not products described as self-hosted libraries. Neither vendor publishes an open-source license, self-hosting option or data-export contract in the product pages. That leaves key control questions for procurement: ask what transaction, customer and reconciliation data you can export, in which formats, and how long access continues after termination. Integration creates dependency on each provider’s payment APIs and operational tooling; switching may require adapting payment flows and reconciling stored payment references. The pages describe payment-data sharing for Braintree and a centralized payments and financial-products stack for Adyen, but do not specify a portable data format or migration path. Get those terms in writing before using either platform as the only system of record for payment operations.
