This is the perfect Appsumo tool, it is cheap, works out of the box with no settings, you can still customize how it works to your liking or project. It gets updated regularly, super fast to load. It had some hiccups when I first bought it, but now it seems like they have gone for good as I'm having no problems for the last few weeks.

I do a lot of PWA and trying to get a native performance out of them while having the optimal ease of use on both desktop and mobile, and this is just about the best for my case. Thank you devs, great job!
