BFF Pattern

Lesson in the API Design Roadmap · Stage 12: API Testing

Last updated 14 September 2026

What is BFF Pattern?

The Backend for Frontend (BFF) pattern involves creating a dedicated API layer for each type of client, typically one BFF for web, one for mobile, and possibly one for third-party consumers. Rather than forcing all clients to use a single general-purpose API, each BFF is tailored to the exact data shape and interaction patterns its client needs. This reduces over-fetching, simplifies client logic, and allows each frontend team to evolve their API contract independently without affecting other clients.
