## What it is
JStack is a lightweight, end-to-end typesafe framework for building fast Next.js 15 applications, built on Hono, Tailwind, and Drizzle ORM. It provides a fullstack starter stack inspired by the T3 Stack and tRPC with type-safe API routing.

## Use cases
- build end-to-end typesafe Next.js apps
- create type-safe API routes in Next.js
- fullstack TypeScript starter with Hono and Drizzle
- tRPC alternative for Next.js App Router
- build lightweight fast web apps with Next.js 15
- set up a fullstack project with Tailwind and Drizzle ORM

## When to choose
- you want end-to-end type safety across a Next.js app's API and frontend
- you like the T3 Stack/tRPC developer experience but want a Hono-based, lightweight alternative
- you're starting a new Next.js 15 project with Tailwind and Drizzle

## When to avoid
- you don't use Next.js or React
- you need a framework with a long track record and large ecosystem
- you prefer a different ORM, styling solution, or backend runtime
