WunderGraph is a free and open-source framework that optimizes frontend, full-stack, and backend developer workflows through the use of Backends-for-Frontends (BFF) architecture. It addresses the drawbacks of the BFF pattern by using GraphQL in a build-time manner, eliminating the need for resolvers, caching, and security concerns associated with public GraphQL APIs. WunderGraph generates persisted queries that can be accessed by clients during runtime, allowing for traditional REST-style caching and improved performance. The framework also supports typesafe development from front to back, live queries, S3-compatible storage, OIDC/non-OIDC compatible auth providers, and more. It makes BFF development accessible and joyful without compromising on end-to-end typesafety.
