Stylist — https://stylist.atlistmaps.com/
Introducing Stylist: an easier way to create Google Map styles.
For a long time the way to create custom Google Map styles was to use Styles Editor — a tool by Google which I've used hundreds of times.
The thing with Styles Editor is that it's a little intimidating and it has a lot of options that most maps won't need to touch.
We built Stylist to be a simpler, easier to use way to create custom styles.
Stylist is not as powerful as Google's Style Editor — but that was never our goal. Our goal was to create an easier to use tool.
Hope it's helpful to you!
