Feature.js is a fast, dependency-free 1kb browser feature detection library written in plain JavaScript. It lets developers test for capabilities like WebGL, canvas, SVG, and touch to build progressively enhanced web experiences.

Use cases

• detect browser feature support in javascript
• check if webgl is supported in the user's browser
• add css classes for supported features like modernizr
• build progressively enhanced web experiences
• detect touch event support in the browser
• run all browser capability tests at once

When to choose

• you need a tiny, dependency-free feature detection library
• you want a lightweight modernizr alternative
• you want tests to run lazily only when requested for performance

When to avoid

• you need comprehensive, actively maintained feature detection with broad test coverage
• you rely on accurate touchscreen detection, which is inherently unreliable
• you need a library with an explicit license or active development
