GraphQL vs REST in Strapi: Choosing the Right One for Your Site

Strapi exposes both REST and GraphQL. Your choice affects how you query, how much you over-fetch, and what tooling you use.

REST: simple and predictable

REST in Strapi is straightforward: one endpoint per content type (e.g. GET /api/posts), with query params for populate, filters, and pagination. No extra setup; you get JSON. It’s easy to cache (by URL), easy to debug (just hit the URL), and works with any client. The downside is you often get more or less than you need: populating a relation can pull in extra fields, and multiple resources may require multiple requests. For many sites, that’s fine: a single “get post by slug” with a controlled populate is enough.

GraphQL: ask for exactly what you need

With the GraphQL plugin, you get a single endpoint and declare the fields and relations you want in each query. That can reduce over-fetching and round trips (e.g. post with author and cover in one query). The tradeoff is complexity: you need a GraphQL client (or fetch with a query string), schema awareness, and sometimes more code for simple cases. GraphQL shines when you have many content types and many views that need different shapes of the same data; for a simple blog or a few content types, REST is often enough.

query PostBySlug($slug: String!) {
  posts(filters: { slug: { eq: $slug } }, publicationState: LIVE) {
    data {
      id
      attributes {
        title
        slug
        excerpt
        content
        publishedAt
        cover { data { attributes { url, alternativeText } } }
        author { data { attributes { name } } }
      }
    }
  }
}

Caching and tooling

REST is easy to cache by URL (CDN, fetch cache). GraphQL is usually POST and one endpoint, so caching by URL is less useful; you may rely on client-side cache (e.g. Apollo) or short-lived server cache. For static or ISR sites, REST plus Next.js fetch cache is simple. For highly dynamic or multi-client apps, GraphQL’s flexibility can be worth the tooling.

Recommendation

Start with REST if your front end has a small set of data needs (e.g. list + single post, a few relations). Add GraphQL if you find yourself making many REST calls or over-fetching a lot and you’re willing to maintain GraphQL queries and types. For most marketing sites and blogs, REST and a thin fetch layer are enough; choose GraphQL when the data shape and client needs justify it.

Summary

Use REST for simplicity, caching, and straightforward needs. Use GraphQL when you need precise fields and relations and are okay with the extra setup. For most Strapi + Next.js sites, REST is the right default; switch to GraphQL when the benefits clearly outweigh the cost.
