GraphQL schemas are easier to reason about when you can build them piece by piece instead of juggling raw SDL from memory. A visual schema generator helps you define types, queries, and mutations and immediately see the resulting SDL.
What Is the GraphQL Schema Generator?
GraphQL Schema Generator is one of the tools in WebdevToolbox’s API Tools category. Visually build GraphQL types, queries, and mutations into valid SDL output, making schema drafting faster for prototypes and production planning alike. It runs entirely in your browser — no server uploads, no accounts, no waiting.
How to Use It
- Open the tool at /tools/graphql-schema-generator.
- Add types, fields, queries, and mutations using the builder controls.
- Review the live SDL output to confirm names, arguments, and return types.
- Copy the generated schema and paste it into your GraphQL server or design document.
Key Features
- Visual schema building — create types and operations without writing every SDL line by hand.
- Queries and mutations support — define the public API shape alongside your object types.
- Valid SDL output — produce schema text ready for review or implementation.
- Helpful for prototyping — sketch data models before wiring resolvers.
- 100% client-side — your schema work stays in the browser.
When to Use the GraphQL Schema Generator
- API design sessions — model a new GraphQL surface during planning or whiteboarding.
- Prototype scaffolding — create starter SDL before building resolvers and tests.
- Schema reviews — share a compact generated draft with teammates for feedback.
