AWS AppSync

Serverless GraphQL and Pub/Sub API service — single endpoint over multiple data sources, with built-in real-time subscriptions and offline sync/conflict resolution. Most-used open-source equivalent is Hasura — instant GraphQL API generation over existing data with real-time subscriptions; Apollo Server is common when building the GraphQL layer by hand rather than auto-generating it.
