Internet-scale data is a powerful tool to understand what properties are important to the real web, and what APIs are interoperable across browsers. Now you can access the same data we use to plan the future of the web platform and use it to inform your own development.
We use data gathered from various large-scale crawlers to see which front-end APIs are actually used on real sites across the web. This section not only allows you to see which APIs are the most used, but also which sites are using them and how they're being used.Explore usage
The API Catalog compares the type system of top browsers. When combined with specification data, this reveals overlaps and differences between each browser’s implementation. We make this data publicly available to encourage collaboration between browser vendors and the web community to build a more interoperable web platform.Explore catalog
