Show HN: Devtools Responsive Mode on Steroids

I made this tool that lets you see any site - on all devices - at the same time. Imagine devtools device preview, but you can see all the devices simultaneously - thats what this is. You can pick and choose devices as needed.

It works on localhost sites too, and even supports hot reloading so you can see instantaneous changes as you develop.

I made this because I'm not a good frontend dev, I struggle with responsive designs, and found devtools cumbersome to use, and other existing tools were very broken.

As of my last checkup, this is the only extension of its type in the world that actually works.

Been working on this for over 8 months, has been a blast and I've pushed many bug fixes the last month

Happy to take any questions
