As Salam o Alaikum.

I really am excited for the al-Quran web version as on Linux we can use it as well without any issues, and the suggestion is to enable the website to cache locally so even if we do not have internet connected but have already downloaded the website in cache, we can still use it which will make it so much accessible.

I have seen this on other websites so it must be possible very likely.

Jazakumullahu khairan
