Zero-Server Privacy Guarantee
All OpenAPI specs, internal models, and confidential API endpoints are parsed exclusively in your browser memory. Nothing is ever sent to external cloud servers.

Automatically synthesizes Query fields from GET requests, Mutation fields with strongly typed inputs from POST/PUT/PATCH/DELETE endpoints, and maps JSON schemas to GraphQL object types.
Production Apollo & Relay Ready
Outputs standard GraphQL Schema Definition Language compliant with Apollo Server, GraphQL Yoga, Nexus, AWS AppSync, Hasura, and client tooling like Codegen.
