GraphQL vs REST

TL;DR: GraphQL gives flexibility and efficiency, while REST is simple and well-established.


Key Differences

AspectGraphQLREST
Data FetchingSingle endpoint, client defines response shapeMultiple endpoints, fixed responses
Over-fetchingNone - you get exactly what you ask forCommon, often retrieving unused fields
VersioningNo versioning needed - evolve the schemaNew versions created for changes (v1, v2, etc.)
Real-Time SupportBuilt-in via subscriptionsRequires workarounds (WebSockets, polling)

Use GraphQL When...

  • Your UI is complex and data-heavy
  • You need to iterate fast without breaking clients
  • You want strong typing and introspection tools

Use REST When...

  • You need something simple and widely supported
  • Your endpoints are stable and rarely change
  • You don’t need advanced query flexibility
