Electron.

WebView2 is basically the modern equivalent of MSHTML.dll (except it runs the Blink/Chromium code out-of-proc), whereas Electron is a more than just a white-label web-browser: it also bundles NodeJS and it provides a runtime environment with its own platform API (and with NodeJS) so that HTML+JS-based applications can have more-or-less do the same things as native code.
