Ask HN: Is there a hackable web browser?

Vivaldi might be your best bet: https://vivaldi.com

Interacting with disk isn't easy with Chrome, but using something like Styler or GreaseMonkey (or whatever it's called now) lets you mess with a page however you want.

The overhead of an extension is pretty small, once you actually build it and set your browser to developer mode.

does vivaldi, have a plugin framework, that help us interact and save dom nodes ?

It doesn't seem to be actively developed, and may not work well out of the box, but https://www.uzbl.org/ may be an option, or at least give some inspiration.

Thank you for the reference. Seems promising, but let me use and see !

Electron?

SO electron is again chrome. Doesn't it shield DOM and allow access only through content scripts. SO isn't the same model available in Electron ?
