It's so cool seeing this on the HN homepage! Hey folks, I'm the solo creator of Polypane, the web browser for developers.<p>This latest release has a new feature called Portal, that lets you share your localhost with any device (local network or through a randomly generated public URL).<p>That's cool but what's new compared to other similar tools is that anything you do in Polypane, like scrolling, clicking and typing, but also our layout debugging and any editing you do in the Polypane devtools also happens in all of the connected browsers, so you can quickly test fixes across rendering engines, or share your localhost with a team mate and suggest changes on the fly.<p>Hope you all check it out :)
