GraphQL Is Still Better Than tRPC 2.0 for Public APIs: 1-Year Case Study at Stripe
Stripe conducted a 1-year pilot comparing GraphQL and tRPC 2.0 for public APIs, finding GraphQL superior across key metrics. Despite tRPC 2.0's type safety benefits for TypeScript users, it underperformed in adoption, onboarding speed, and cross-language support. GraphQL's flexibility, tooling, and language-agnostic design made it more effective for Stripe's diverse developer ecosystem.
- ▪GraphQL endpoints saw 3x higher adoption among new external developers compared to tRPC 2.0.
- ▪New developers achieved first successful API calls in 12 minutes with GraphQL versus 28 minutes with tRPC 2.0.
- ▪tRPC 2.0 generated 2.2x more support tickets, with 68% related to type mismatches and schema issues.
- ▪GraphQL reduced overfetching by 72% and allowed flexible queries, while tRPC 2.0 required additional custom procedures to match functionality.
- ▪tRPC 2.0's TypeScript-first design limited support for non-TypeScript languages, requiring custom adapters that lacked full type safety.
