Well, recently I discovered PWA (Progressive Web Apps) that you can use in most popular browsers. The concept is the same used by firework, you can create an app in Safari or Chrome easily (for instamce in Chrome, click on Sttings, More tools > Create Shortcut > Open As Window) and then you just created a MacOS app in Applications. This app can be used on the desktop, on the dock or even in a folder. Why shoud I buy use or buy Firework ?.
