# Query Plan
> The router allows you to request the query plan and you can view the same in the playground
Include the header `X-WG-Include-Query-Plan` to receive the query plan in the extensions field. The below headers are also useful
`X-WG-Skip-Loader` : Skip requests to subgraph, this will return data as null
`X-WG-Disable-Tracing` : This will ensure that requests for query plan are not traced in the router
Plans for [`@defer` operations](/router/incremental-delivery) include the primary execution and every planned deferred branch. A request that combines `X-WG-Include-Query-Plan: true` with `X-WG-Skip-Loader: true` returns that complete plan in one JSON response with `data: null`; it does not execute subgraphs or require multipart response negotiation.
