WunderGraph features

  • Connect any service. Expose gRPC, Kafka, NATS or Redis services through a unified GraphQL router without extra infrastructure.
  • Real-time streams. Router handles subscriptions, aggregating events from Kafka, NATS or Redis and pushes updates to clients.
  • MCP Gateway. One gateway turns approved operations into agent-ready tools with built-in authentication, eliminating separate MCP servers.
  • Graph governance hub. Shared canvas for schema design, review, ownership, proposals and safe deployments with audit logs and RBAC.
  • Cache warming. Pre-warm query planning cache to eliminate long planning delays for high-load scenarios.
