What is Can I Use?
Can I Use is the go-to lookup for web developers who want to know whether a feature will work for their users. Search for something like CSS Grid, WebP, AVIF or dvh units and you get a support table showing which versions of Chrome, Safari, Firefox, Edge and mobile browsers handle it fully, partly or not at all, along with notes and known issues.
Usage share data from StatCounter turns the table into a practical answer: what percentage of people can use this today. The site also lets you compare browsers, browse a full feature index, see a browser usage table and vote on features to add. It was created and is maintained by Alexis Deveria, with data contributions from the GitHub community, and is free with ads.
