IDEs -> vscode

thunderbird ->Gmail

Ms office > gdocs

Msn messenger -> Hangouts

Etc.

At least for most (non professional) users

Edit: and often you are better off using webapps because they are sandboxed.

Webapps sandbox is useless when they actually need someone's else computer to do any valuable work.

VS Code even includes native code (ripgrep written in Rust), so I'm not sure if it should count.

And in my experience Microsoft Office is still used more than Google Docs for non professional users, but YMMV.

Hangouts is also way behind natives apps like WhatsApp, iMessage, Telegram in market share.

vscode may or may not count as a SPA, that's beside the point. It is certainly based on and would not be possible without web technologies. And illustrates perfectly why today it is not possible anymore to become a web developer just by "viewing the source".
