Can I use... is an online reference that provides up-to-date browser support tables for web technologies such as HTML5, CSS3, JavaScript APIs, and related features.

It aggregates usage statistics and displays support status across major browsers and versions, helping developers understand which features are safe to use in production.

The site solves the common challenge of cross-browser compatibility by giving clear, color-coded tables indicating support, partial support, or lack of support for specific web features. Developers can search for features, view detailed support notes, and use integrated usage data to make informed decisions about which technologies to adopt.

Can I use... is widely used in frontend development workflows to plan progressive enhancement, polyfills, and fallbacks, reducing bugs and improving user experience across diverse browsers and devices.

Key features include:

• Browser compatibility tables for web features
• Color-coded support status (supported/partial/unsupported)
• Usage statistics by global browser share
• Searchable feature index
• Integration with external testing tools (e.g., BrowserStack)

Common use cases include:

• Checking whether a CSS property or HTML API is supported in target browsers
• Planning fallbacks for unsupported features
• Guiding progressive enhancement strategies
• Educating teams on browser support
• Optimizing web application compatibility
