## What it is
A fullstack SaaS boilerplate built with tRPC, Fastify, React 19, Drizzle ORM, and Better Auth, with integrated AI chat via OpenAI and Server-Sent Events. It provides a production-ready starting point with authentication, database setup, testing, and a monorepo structure using pnpm workspaces.

## Use cases
- start a fullstack SaaS app with typesafe APIs
- build a SaaS product with authentication and Postgres already wired up
- add an AI chat feature to a React app using OpenAI and SSE
- bootstrap a TypeScript monorepo with Fastify and tRPC
- learn how to structure a fullstack app with Drizzle ORM and Better Auth
- quickly prototype a SaaS with a modern React and Tailwind stack

## When to choose
- you want a batteries-included TypeScript fullstack starter with auth, ORM, and AI chat
- you prefer tRPC end-to-end typesafety over REST or GraphQL
- you want a Fastify backend with React 19 and Tailwind v4 frontend
- you need SSE-based streaming chat without a WebSocket server

## When to avoid
- you need a framework with a large ecosystem or long-term enterprise support rather than a starter template
- you use a database other than Postgres or a stack outside Node.js/TypeScript
- you want a minimal scaffold you will heavily restructure anyway
- you need mobile or native desktop targets
