ShowcaseHow Candid sped up API development by 50% by going schema first
Fern transforms API development at Candid by centralizing API definitions in YAML and automating code generation. This eliminates manual boilerplate across backend (95,000 lines) and frontend (30,000 lines), ensuring consistency between Pydantic models, FastAPI routes, TypeScript clients, and upcoming documentation. The schema-first approach prevents drift bugs through a single source of truth, with plans to extend into customer-facing SDKs.
