## What it is
Kobweb is an opinionated Kotlin full-stack web framework built on Compose HTML, inspired by Next.js and Chakra UI. It provides page routing, live reloading, a Silk UI component library, server API routes, markdown support, and SEO-friendly static exports.

## Use cases
- build a full-stack web app in Kotlin
- create a static site with SEO-friendly exports using Compose HTML
- add server API endpoints with @Api annotations in Kotlin
- build a website with light/dark mode and a component library
- migrate from Next.js-style routing to a Kotlin-based framework
- write reactive UIs with Compose for the web
- set up a Kotlin web project with live reloading

## When to choose
- you know Kotlin or Compose and want to build websites or web apps with it
- you want a Next.js-like developer experience in the Kotlin ecosystem
- you need both frontend pages and backend API routes in one codebase
- you want built-in routing, theming, and live reloading out of the box

## When to avoid
- your team primarily works in JavaScript or TypeScript
- you need a battle-tested 1.0 framework for a large production system (Kobweb is pre-1.0)
- you want to avoid opinionated framework conventions
- you need a framework with a very large plugin ecosystem
