GraphQL Schema Viewer
Visualize your GraphQL Schema Definition Language (SDL) files. Search and inspect mutations, custom types, and inputs dynamically.
Visualizing GraphQL SDL Trees
GraphQL schemas can scale to contain hundreds of types, queries, and mutations, making it difficult to inspect schemas via flat text files.
Our online viewer parses schema definitions and renders them as interactive cards, allowing you to search types and inspect properties easily.
Frequently Asked Questions
What is GraphQL SDL?
GraphQL Schema Definition Language (SDL) is the standard syntax used to describe the capabilities and schemas of a GraphQL API (types, inputs, queries, mutations).
How does the visual accordion view help?
It structures your schema text into interactive, searchable cards. Clicking on a card expands it to display its fields, argument options, and type details.
Is my schema definition private?
Yes. The parsing logic executes entirely inside your browser memory. No schema details are sent over the network.
