So weird! I was just looking for this 2 days ago, and was like, "Huh, I thought they had a web app??" Turns out it was always for devices native only. I had no idea this was coming but 2 days ago was the first time I was looking for a web version! Hahaha! :)

edit: Just tested it. Nice! Faster than Google Maps in my estimation. (panning and zooming the map builds and focuses faster). Google, please don't delete my account for criticism! hahaha! :)
