Apollo Server 4 (Release Candidate)

Apollo Server is an open-source, spec-compliant GraphQL server that's compatible with any GraphQL client, including Apollo Client. It's the best way to build a production-ready, self-documenting GraphQL API that can use data from any source.

You can use Apollo Server as:

• The GraphQL server for a subgraph in a federated supergraph
• A stand-alone GraphQL server
• An add-on to your application's existing Node.js middleware (such as Express, AWS Lambda, or Fastify)

Apollo Server provides:

• Straightforward setup, so your client developers can start fetching data quickly
• Incremental adoption, enabling you to add features as they're needed
• Universal compatibility with any data source, any build tool, and any GraphQL client
• Production readiness, enabling you to confidently run your graph in production
