## What it is
KVision is an object-oriented web framework for Kotlin/JS that lets developers build modern web UIs entirely in Kotlin without HTML, CSS, or JavaScript. It provides a type-safe DSL of ready-made GUI components and integrates with server frameworks like Ktor, Spring Boot, and Micronaut for fullstack applications with shared code.

## Use cases
- build web apps in kotlin without writing javascript
- create type-safe frontend ui with kotlin dsl
- develop fullstack kotlin applications with shared code
- build reactive web interfaces with kotlin/js
- replace html css javascript with kotlin components
- integrate kotlin frontend with spring boot or ktor backend

## When to choose
- your team knows Kotlin and wants a fully type-safe frontend
- you want to build fullstack apps sharing data models between client and server
- you prefer component-based GUI building over HTML/CSS templates

## When to avoid
- you need a large JavaScript/React ecosystem of third-party components
- your team primarily works in JavaScript or TypeScript
- you need fine-grained control over generated HTML and CSS
