GraphQL Designer provides a complete visual and code-first workflow for creating, editing, and managing GraphQL schemas for SubQuery projects. It combines intuitive drag-and-drop entity relationship diagrams with a powerful code editor, making schema design accessible to both visual and code-oriented developers.
The platform includes built-in validation, version control with diff visualization, and collaboration features that help teams work together efficiently on complex indexing projects.
Capabilities
What the platform delivers
Visual + code-first workflow
Drag-and-drop ER diagrams sit alongside a full-featured editor so architects can switch between tactile design and precise code edits instantly.
Validation & auto-correction
Embedded GraphQL validator, type auto-fixes, and migration helpers convert schemas from The Graph or legacy SubQuery projects with one click.
Version intelligence
Every save becomes a revision. Upload a new schema and GraphQL Designer highlights diffs between versions so indexers know exactly what changed before redeploying.
Collaboration & access control
Personal cabinet, private/public visibility, and granular roles mean studios can demo on stage, ship to clients, or keep experiments internal.
Everywhere-ready UX
Optimized for touch-first tablets, phones, and laptops, making it perfect for conferences, live workshops, and remote reviews.

Why it matters to indexers
Indexers and data providers no longer guess what changed between releases. Upload a new schema and GraphQL Designer highlights the differences, ensuring infrastructure teams know when to refresh mappings, redeploy workers, or adjust strategies.
Because the UI embraces touchscreens, teams can demo live diagrams at conferences or during customer workshops without additional tools. The platform becomes a single source of truth for SubQuery schema design, documentation, and publication.
