Tech Stack

Core Technology​

  • Node.js (v24): The runtime for the Redwood backend services, managed with Yarn 4
  • TypeScript: The language used for the Redwood backend services
  • Socket.IO: The network layer used for connections with any of the Node.js services (websockets only)
  • Prisma (v6): The ORM and schema migration tool for the Director and Realm databases
  • PostgreSQL: Relational database used by Redwood in Kubernetes deployments
    • SQLite: Used by the Dev Initiator so local development without Kubernetes needs zero database setup
  • Redis: Used for data that needs to support horizontal scaling as well as providing a pub/sub broker between frontend and backend services
    • BullMQ: Job queues on top of Redis, used by Ticketing and other horizontally scaled work
    • Custom stub: Redis doesn't run natively on Windows, so Redwood provides a custom pure-JS single-process stub for the Redis API for testing and most development cases (the Dev Initiator default)
    • Memurai: For advanced Windows-only dev environments where the stub doesn't work out, Memurai is a full replacement for Redis
  • Docker: The containerization system for reproducible microservice environments
  • Kubernetes aka K8s: Container orchestration and scheduling
  • Pulumi and Helm: Infrastructure-as-Code for deploying Redwood and its dependencies to Kubernetes
  • ingress-nginx: Routes external traffic to the right service by hostname
  • Agones: An extension to Kubernetes that assists with deploying and scaling game server pods in a Kubernetes cluster based on demand
  • Open Match: The optional large-scale matchmaking system used by Redwood
  • SeaweedFS: S3-compatible object storage for blob storage in Kubernetes
  • ejabberd: For Text Chat support

The versions of the Kubernetes dependencies are listed in Deploying Locally.
