Stripe and Braintree are the two most popular developer-focused payment processors. Both offer robust APIs, extensive documentation, and support for complex payment flows. Braintree is owned by PayPal, while Stripe is independent. The fee structures differ in subtle but important ways that can add up at scale.
Fee Comparison
Stripe charges 2.9% + $0.30 per online transaction. Braintree charges 2.59% + $0.49. The math gets interesting depending on your average transaction size. On a $50 transaction, Stripe takes $1.75 and Braintree takes $1.79 — nearly identical. On a $200 transaction, Stripe takes $6.10 and Braintree takes $5.67. Braintree's lower percentage rate saves money on larger transactions, while its higher flat fee hurts on smaller ones.
ACH and Bank Transfers
Both offer competitive ACH rates. Stripe charges 0.8% capped at $5 for ACH Direct Debit. Braintree charges 0.75% capped at $5. The difference is negligible, but Braintree has a slight edge for bank transfer payments.
PayPal and Venmo Integration
Braintree's killer feature is native PayPal and Venmo integration. Since Braintree is owned by PayPal, it offers seamless PayPal checkout, Venmo acceptance, and PayPal Credit — all through a single integration. Stripe supports PayPal through third-party plugins, but it's not as tightly integrated. If accepting PayPal and Venmo is important to your business, Braintree makes it significantly easier.
Developer Experience
Stripe is widely regarded as having the best API documentation in the payments industry. Its developer tools, webhooks, testing environment, and dashboard are best-in-class. Braintree's API is solid but less polished. Stripe also has a broader ecosystem with Stripe Atlas, Stripe Tax, Stripe Billing, and more. For complex integrations, most developers prefer working with Stripe.
The choice often comes down to priorities: Braintree for native PayPal/Venmo support and lower rates on large transactions, Stripe for superior developer tools and a broader platform ecosystem.
