GraphQL Query Complexity Analysis

How SculptQL analyzes query complexity to prevent performance problems before they happen.

GraphQL Query Complexity Analysis

GraphQL's flexibility is a double-edged sword. Clients can request deeply nested data that kills your server.

The Problem

Complexity Calculation

We assign costs to fields and multiply by list sizes. The query above might have complexity 100 * 100 * 100 * 100 = 100,000,000.

Setting Limits

SculptQL visualizes this complexity before execution, helping developers understand the cost of their queries and refactor before production.
