This is a good concept for developers. However, most of the items offered here are available for free in Microsoft DevToys which can be downloaded for free in the Microsoft store, (
https://apps.microsoft.com/store...). I guess this can be a good alternative for Mac users using Chrome, (eventually Firefox).
On the other hand, this app does have some nice features that DevToys is missing, and if more features like these are added that would justify my purchase.
