It makes me question, is there any way to run a slim browser for these kind of tools?
It would be cool to have a tool that would:
* run a very slim browser tab for each tool
* I cloud load/save sites into tools (So I can really run them offline)
* Could have a shortcut or a starting page that's just links to my saved tools
Considering this tool uses JavaScript rendering, I'm not sure you could get away with a "slim browser". You're going to need all the bloat that makes CSR work.
Saw this on Hacker News a short while back and it was pretty easy to set up. Might be pretty close to what you're looking for. It aims to be a sort of a replacement for what Electron does, without embedding a full browser.
