kotlinx.html is an official JetBrains Kotlin library providing a type-safe DSL for building HTML, either streaming to a Writer/Appendable or constructing DOM trees. It supports all Kotlin Multiplatform targets including JVM, JS, and WasmJS.

Use cases

• generate html from kotlin code
• build dom trees in kotlin for the browser
• render server-side html templates in kotlin
• write type-safe html without string concatenation
• create html for kotlin/wasm web apps
• stream html output to a writer in a ktor server

When to choose

• you write Kotlin and want compile-time-safe HTML generation
• you need HTML rendering across JVM, JS, and WasmJS targets
• you prefer building DOM programmatically over hand-written HTML templates

When to avoid

• your stack is not Kotlin or JVM-based
• you need designer-friendly template files rather than code-based markup
• you need a full frontend framework with state management
