Convert GraphQL SDL type schemas into strongly typed TypeScript interfaces with optional field mapping.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Paste your GraphQL SDL type schemas (type User { ... }).
Review the mapped TypeScript interfaces and optional/required fields.
Copy the TypeScript definitions or download the types.d.ts file.
GraphQL fields ending with an exclamation mark (!) are mapped to required TypeScript fields, while others are mapped as optional (field?: type).
[String!] and [User!] are automatically mapped to string[] and User[].
