How do I navigate to a specific type?

Click any type name in the schema view to navigate to it. Or press Cmd/Ctrl+K to open the search modal and jump to any type by name.

Where does usage data come from?

Usage data is pulled from Cosmo's analytics pipeline. Analytics must be enabled for usage data to appear.

Can I see which fields require authentication?

Yes. The Schema Explorer shows @authenticated and @requiresScopes directives inline. Click "View scopes" on a protected field to see the required scopes.

How do I see all deprecated fields?

The deprecated fields view aggregates all deprecated fields across the schema in one place, alongside their usage metrics.

Does the Schema Explorer show subgraph-level information?

The Schema Explorer shows the composed federated schema. It reflects the merged view of all subgraphs.

Is usage data required to use the Schema Explorer?

No. Navigation, search, and deprecated fields are available without analytics. Usage metrics require analytics to be enabled.

Schema Explorer for Federated GraphQL | Cosmo by WunderGraph

The problem

Federated schemas are hard to read

A composed federated schema is large and interconnected. Raw SDL gives you no usage data, no interactive navigation, and no way to see authorization requirements at a glance.

Raw SDL files are hard to navigate

A federated schema can span thousands of lines across multiple subgraphs. Finding a specific type or understanding its relationships requires text search and cross-file jumping.

Field usage is invisible without dedicated tooling

Teams cannot tell which fields clients actually query. Decisions about deprecation and removal are guesswork without usage data.

Authentication requirements are scattered

Knowing which fields require @authenticated or specific scopes means reading the schema definition line by line. There is no aggregated view.

Our solution

Interactive schema navigation with live usage data

The Schema Explorer renders the composed federated schema as a clickable UI. Navigate between types, search by name, and see real usage data from Cosmo analytics alongside every field definition.

From schema to insight

The Schema Explorer parses the composed federated schema and renders it as an interactive UI.
Click any type to navigate to it. Objects, interfaces, unions, enums, and inputs are all navigable.
The details panel shows all fields, arguments, and descriptions for the selected type.
Press Cmd/Ctrl+K to open the search modal and jump to any type by name.
Usage data — pulled from Cosmo analytics — appears alongside field definitions.
The deprecated fields view aggregates all deprecated fields across the schema in one place, with their usage metrics.

Click to navigate. Search to jump. Analytics to decide.

Before & After

Before Cosmo	With Cosmo
Read raw SDL to understand type relationships	Click through types interactively
No visibility into which fields clients use	Usage metrics displayed alongside field definitions
Search through files for specific types	Cmd/Ctrl+K jumps to any type instantly
Auth requirements require manual SDL inspection	@authenticated and @requiresScopes visible inline

Authorization

Authentication visibility

@authenticated: Fields and types requiring authentication are listed in the Authenticated Types and Fields view.
@requiresScopes: Click "View scopes" on any protected field to see the required scopes.

How the Schema Explorer works

01

Click-through navigation.

Navigate

Open the Schema Explorer in Cosmo Studio. Start at the Query root and click through types to explore the full graph.

02

Instant type search.

Search

Press Cmd/Ctrl+K to open the search modal. Jump to any type in the schema by name without scrolling.

03

Analytics-backed usage data.

Check usage

View real usage data next to field definitions. See which fields clients actually query and which have no traffic.

04

Deprecated fields + usage in one view.

Review deprecated

Open the deprecated fields view to see all deprecated fields in the schema alongside their usage metrics. Identify which are safe to remove.

Capabilities

What you get with Schema Explorer

Interactive navigation
