What are the main differences between GraphQL and REST?
Updated Apr 28, 2026
Short answer
REST uses multiple endpoints returning fixed data structures (over/under-fetching). GraphQL uses a single endpoint returning exactly the data requested.
Deep explanation
In REST, the server determines the shape of the response. In GraphQL, the client determines the shape. GraphQL prevents over-fetching (getting more data than needed) and under-fetching (needing multiple requests to get all required data).
Real-world example
Replacing 5 distinct REST calls on a dashboard page with 1 single GraphQL query.
Common mistakes
- Assuming REST is entirely obsolete
- REST is still better for simple APIs or strict HTTP-level caching.
Follow-up questions
- How does HTTP caching differ between the two?
