Placemark is the map editor software-as-a-service that I built for several years. It’s a website where you can import, create, edit, export, publish, and visualize geospatial data.
The code is on GitHub and already receiving contributions.
You can serve PMTiles directly from a cloud object storage but in some cases, you want to control who accesses data and how often—and you need a server for that. Craig Kochis wrote up two examples of how to serve PMTiles using a NodeJS server application from a co-located file and S3.
