Tailcall · GraphQL Specification

Tailcall GraphQL API

Tailcall is a high-performance GraphQL gateway and runtime built in Rust. It does not expose a fixed hosted GraphQL API endpoint — instead, it is a self-hosted runtime that developers configure and deploy themselves. The runtime generates a unified GraphQL schema at startup by composing multiple upstream REST, gRPC, and GraphQL APIs using declarative SDL files annotated with custom directives.
