Flarum is modern forum software that I love and I have just released my sixth extension for this platform. This one makes Flarum a PWA (Progressive Web App).
To put it simply, this means users will be able to “install” your Flarum forum and it will look more like a native app; and it will be added to the user’s desktop or home screen.
Here’s a video showing what it looks like after installing (notice the app icon and how it is a frameless non-browser window that pops up.)
