## What it is
Ratzilla is a Rust framework for building terminal-themed web applications using Ratatui widgets compiled to WebAssembly. It renders TUI-style interfaces in the browser via DOM or canvas backends, with project templates using Trunk.

## Use cases
- build terminal-themed web apps in rust
- render ratatui tui widgets in the browser
- create retro terminal-style dashboards with webassembly
- port a rust tui to the web
- build a browser-based terminal ui with keyboard events

## When to choose
- you want ratatui's widget model and terminal aesthetics in a web app
- you prefer writing frontend logic in rust compiled to wasm
- you want a lightweight alternative to dom-heavy frontend frameworks for stylized uis

## When to avoid
- you need a conventional dom-based web ui with standard html/css components
- you need accessibility features or seo-friendly server-rendered content
- you want a mature production frontend framework with a large ecosystem

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, frontend-framework, ui-components, wasm
- domain: web-development, frontend, developer-tools
- platform: wasm, browser, rust
- tags: ratatui, tui, terminal-aesthetics, webassembly, trunk, web
