REST vs GraphQL
Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.
Quick answer: REST exposes resources via URLs (GET /users/123). GraphQL exposes a single endpoint where the client specifies exactly what data to fetch. REST is simpler, more cacheable, and is the dominant standard. GraphQL is more flexible, prevents over/under-fetching, and is best for complex frontends with varied data needs.
Decision guide — when to use which
Use REST when…
Public APIs (Twitter, GitHub, Stripe), CDN caching, simple CRUD, microservices.
Use GraphQL when…
Mobile apps (one round-trip for complex data), unified frontend across multiple services, schema-first development.
📊 Side-by-side comparison
| Aspect | REST | GraphQL |
|---|---|---|
| Endpoints | Multiple (one per resource) | One (single endpoint) |
| Data fetching | Over- or under-fetching common | Client specifies exact fields |
| Caching | Trivial (HTTP caching) | Hard (POSTs not cached by default) |
| Type safety | Loose (OpenAPI helps) | Built-in (schema mandatory) |
| Adopted by | GitHub v3, Twitter, Stripe | GitHub v4, Shopify, Facebook |
Frequently asked
?
Is GraphQL replacing REST?
No. GraphQL is gaining ground in specific use cases (mobile apps, microservices aggregation), but REST remains dominant for public APIs because of HTTP caching, simplicity, and broad tooling. Most modern stacks use both.
?
Which is faster?
For simple single-resource queries, REST is faster (better caching). For complex multi-resource queries, GraphQL is faster (one round-trip vs many). The answer depends on the workload.
