## What it is
WebF is a W3C/WHATWG-compliant web runtime for Flutter that implements HTML, CSS, and the DOM with a QuickJS JavaScript engine, rendered by a custom Flutter-based engine rather than a system WebView. It lets developers build native cross-platform apps using web frameworks like React, Vue, and Svelte with direct JavaScript-to-native communication and embedded Flutter widgets.

## Use cases
- build native flutter apps with javascript and css
- run react or vue apps inside flutter without a webview
- ship one codebase to ios android desktop from web tech
- push over-the-air updates to a flutter app without store review
- embed flutter widgets as html elements in a web app
- replace webview with a faster custom rendering engine
- reuse npm ecosystem and tailwindcss in a mobile app

## When to choose
- you want native-like performance and sub-100ms startup instead of a system WebView
- your team knows React/Vue/Svelte and Tailwind but needs Flutter-supported platforms
- you need over-the-air UI updates bypassing app store review
- you want to mix Flutter widgets with web-standard HTML/CSS UI

## When to avoid
- you need a fully compliant general-purpose browser or full web API coverage
- your app must be distributed on Apple App Store or Google Play under GPL-3.0 without a commercial license
- you need pixel-perfect rendering of arbitrary existing websites
- you prefer pure Dart/Flutter development without JavaScript
