I'm working on my side project, a Google My Maps alternative using OpenStreetMap data: https://maphub.net/
Just today I did my biggest feature launch so far, adding real-time collaboration, which might even be a first for map platforms: [1]
Originally I launched MapHub here in 2016 as a Show HN. Ever since I've been running it without any kind of monetization. I'm planning to launch it out-of-beta next month and add freemium packages. Feedback welcome!

The community has started a mapbox-gl-js 1.x fork called maplibre-gl-js, I'll be migrating to it in the future:
