## What it is
A multi-tenant SaaS starter kit built on NestJS with a CQRS, DDD, and event-sourcing microservice architecture. It provides GraphQL APIs via Apollo Federation, gRPC microservices, authentication, and integrations like Stripe, NATS, Consul, and EventStore.

## Use cases
- bootstrap a multi-tenant SaaS backend
- set up a CQRS and event-sourcing microservice architecture
- build a federated GraphQL API gateway
- scaffold a NestJS microservices project with gRPC
- add Stripe billing and authentication to a SaaS starter
- learn DDD patterns in a production-style backend

## When to choose
- starting a scalable multi-tenant SaaS from scratch
- you want CQRS/event-sourcing with GraphQL federation out of the box
- your stack is Node.js/NestJS with NATS, Consul, and EventStore

## When to avoid
- you need a simple monolith or REST-only backend
- your team is unfamiliar with CQRS, DDD, or event sourcing
- you use a stack other than TypeScript/NestJS
- you need a fully finished, non-WIP framework
