GraphQL Placeholder is a zero-config GraphQL API built with NestJS that mirrors the popular JSONPlaceholder dataset, designed for rapid frontend and API prototyping.
It provides a realistic GraphQL playground for experimenting with queries, mutations, relationships, and filters—without setup or authentication.
Frontend and API developers often need a stable, realistic GraphQL backend to prototype features, test data flows, or explore schema design.
GraphQLPlaceholder solves this by exposing familiar JSONPlaceholder data through a clean GraphQL schema with support for relationships and nested queries.
