Tailcall is a high-performance GraphQL runtime written in Rust that lets you build GraphQL backends declaratively by annotating a GraphQL schema with directives like @server and @http, without writing resolver code. It acts as an API orchestration layer and gateway that composes upstream REST, gRPC, and other services into a single GraphQL endpoint.

Use cases

  • expose a unified GraphQL API over existing REST microservices
  • build a backend-for-frontend layer without writing resolvers
  • aggregate multiple upstream APIs into one GraphQL schema
  • run a high-performance GraphQL gateway in front of legacy services
  • define a GraphQL server entirely from a schema file with no code
  • add caching and resiliency to upstream API calls
  • replace a hand-written GraphQL server with a declarative config

When to choose

  • your data lives in existing REST/gRPC/HTTP APIs you want to expose as GraphQL
  • you want schema-first, configuration-driven GraphQL with minimal code
  • you need a fast, Rust-based GraphQL gateway or BFF layer
  • you want built-in caching, batching, and resiliency for upstream calls

When to avoid

  • you need complex custom business logic inside resolvers
  • your data sources are databases rather than HTTP/gRPC services
  • you already have a mature GraphQL server stack your team knows well
  • you need subscriptions or GraphQL features beyond what the runtime supports
