Baseline
Web Platform Baseline brings clarity to information about browser support for web platform features.
Baseline gives you clear information about which web platform features are ready to use in your projects today. When reading an article, or choosing a library for your project, if the features used are all part of Baseline, you can trust the level of browser compatibility.
Who defines Baseline?
Baseline was originated by the Chrome team and is now defined by the WebDX Community Group.
How do things become Baseline?
Baseline has two stages:
- Newly available: The feature is supported by all of the core browsers, and is therefore interoperable.
- Widely available: 30 months have passed since the newly interoperable date. The feature can be used by most sites without worrying about support.
Prior to being Newly available, a feature has Limited availability when it's not yet supported across browsers.
The core browser set
- Chrome (desktop and Android)
- Edge
- Firefox (desktop and Android)
- Safari (macOS and iOS)
