GraphQL Is Still Better Than tRPC 2.0 for Public APIs: 1-Year Case Study at Stripe Stripe has long prioritized developer experience for its public APIs, migrating from REST to GraphQL in 2019 to reduce overfetching, simplify endpoint discovery, and unify access to its payments, billing, and fraud prevention tools. In early 2023, as tRPC 2.0 gained popularity for type-safe internal APIs, our public API team launched a 1-year pilot to test tRPC 2.0 against our existing GraphQL implementation for 15% of public endpoints, including core payments, refunds, and customer management resources. After 12 months of production data, the results confirm GraphQL remains the superior choice for public API ecosystems. Background: The tRPC 2.0 Pilot tRPC 2.0 promises end-to-end type safety between servers and clients with zero build-time overhead, a compelling pitch for teams using TypeScript across their stack. For Stripe’s internal APIs, tRPC 2.0 has driven faster iteration and fewer type-related bugs.…
