## What it is
Vugu is an experimental Go library for building web user interfaces that compile to WebAssembly and run in the browser. Inspired by Vue, it uses single-file .vugu components with Go expressions instead of JavaScript, and includes code generation tools like vugugen.

## Use cases
- build a web frontend in pure Go without JavaScript
- write single-file UI components with Go logic
- create browser apps compiled to WebAssembly
- rapidly prototype web UIs without node or npm
- build small wasm apps with TinyGo for smaller binaries

## When to choose
- you want to write browser UIs in idiomatic Go with no JavaScript toolchain
- you prefer Vue-like single-file components but with Go expressions
- you want a simple build process using standard Go tools
- wasm binary size of a few megabytes is acceptable for your app

## When to avoid
- you need a battle-tested, production-stable framework
- you require minimal payload sizes and broad mobile browser support
- your team works primarily in JavaScript/TypeScript
- you need a large ecosystem of UI components and plugins

## Facets
- artifact type: framework
- maturity: experimental
- function: frontend-framework, ui-components, templating, web-framework
- domain: web-development, frontend, developer-tools
- platform: wasm, browser, go, cross-platform
- tags: webassembly, single-file-components, vue-inspired, no-javascript, tinygo, code-generation
