Apollo Client vs Apollo GraphOS

Apollo Client is a JavaScript library for managing GraphQL data in applications. It can fetch, cache and modify data from local and remote sources, then update the interface as data changes. Developers describe a query and receive its data without manually managing loading states. Normalized caching can make responses to cached queries almost immediate. The core @apollo/client library has built-in React integration, including hooks and Suspense, and the library can be added incrementally to JavaScript or TypeScript applications. It works with any build setup and GraphQL API. Community integrations extend support to frameworks including Angular, Vue, Svelte, Solid.js and Ember, as well as native iOS and Android. Apollo Client also supports GraphOS Router features such as incremental delivery, subscriptions and persisted-query safelisting. Chrome and Firefox extensions provide GraphiQL and tools for inspecting watched queries, mutations and cache. Apollo Client is free and open source. GraphOS Free includes one self-hosted router limited to 60 requests per minute; the separate Developer plan is $5 a month, billed monthly.
