It's barely mentioned on the website (just a tiny reference in the roadmap section) but looking at the Windows nupkg, it's Chromium-based.<p>I wish the devs best of luck and it looks like a cool design, but the Blink / Chromium dominance is too dangerous for the health of the web for me to ever support.
