Native for where?  You can always use stylesheets to adjust the appearance... you can even have targeted stylesheets for the different platforms.  That said, &quot;native&quot; is pretty subjective, as windows has <i>many</i> &quot;native&quot; look&#x2F;feel over generations... Office 2000 vs the latest or Windows across the same timeline... there&#x27;s also GTK vs Qt on Linux, and their themes...<p>Electron is <i>not</i> native, and beyond that, there are too many variables cross platform for anything to look truly native everywhere even for a compiled C++ app without a lot of work.  That said, you can definitely style to a platform more appropriately (again, there is work to that).
