With macOS Sonoma you can turn any web application into an app in your Mac’s Dock thanks to the new “Add to Dock” feature in Safari.
A web-based app is an application that treats a website as the interface. You can access the app from any computer connected to the Internet instead of using an application installed on your Mac.
Since web apps function via a web browser such as Safari, they’re usually accessible from a variety of devices. While native apps require certain operating systems (macOS, Windows, etc.) and software, web applications work for anyone who can access the browsers that support them.
