Is WebF a full browser engine?

No, WebF is a high-performance W3C-compliant runtime built on top of Flutter. It implements core web standards for building apps rather than general-purpose web browsing.

Does this skill support Tailwind CSS?

Yes, it provides compatibility guidance for Tailwind CSS v3. Note that v4 support is currently planned for a future release in 2026.

Why aren't Web Workers supported in WebF?

In WebF, JavaScript already runs on a dedicated background thread separate from the UI thread, providing the performance benefits of workers without the added complexity.

What should I use instead of IndexedDB?

For simple key-value storage, use localStorage. For complex database needs, WebF recommends using native Flutter plugins like sqflite or Hive.

Mobile Development

Verifies Web API and CSS feature compatibility within the WebF Flutter runtime to identify supported standards and native alternatives.

About

The WebF Compatibility Checker is an essential tool for developers bringing web-based applications to Flutter. Since WebF is a specialized runtime rather than a full browser engine, it implements specific W3C standards optimized for performance. This skill helps you quickly determine if JavaScript APIs, DOM methods, and CSS properties are supported, while providing recommended workarounds and native Flutter plugin alternatives for unsupported features like IndexedDB, WebGL, or legacy Float layouts.

Key Features

Direct links to native plugin documentation for environment-specific setup.
Comprehensive Web API support verification for DOM, Networking, and Storage.
1,944 GitHub stars
Version-specific compatibility tracking for popular frameworks like Tailwind CSS.
Interactive guidance for finding native Flutter alternatives for unsupported browser features.
Detailed CSS layout analysis identifying supported Flexbox and hardware-accelerated transforms.

Use Cases

Auditing an existing web codebase before porting it to a Flutter environment using WebF.
Debugging CSS layout inconsistencies between standard browsers and the WebF runtime.
Selecting the correct storage or networking strategy for high-performance Flutter apps.
