I’ve gone through this process for my email client Kanmail [1]. The third party audit is not required for email clients that run on end users computers and store credentials locally.

I use pyinstaller for my Kanmail email client [1] and it’s fantastic, but at creating Mac app bundles or Windows exes. Tried making actual standalone binaries for another project and, as others have mentioned, they’re incredibly slow to startup.

There's pywebview (https://github.com/r0x0r/pywebview/) which is a Python lib that uses whatever native webview implementation exists.

I'm using it on my cross platform email client (https://kanmail.io). - Source: Hacker News / almost 3 years ago
