Protomaps is a full-stack mapping system that's an alternative to proprietary APIs like Google Maps and Mapbox.
The major difference between Protomaps and every other mapping stack is that it is designed to be trivially self-hostable. The entire planet of vector map tiles fits in a single ~100 GB file that can be served directly from S3 to web browsers.
Protomaps is built on top of data sources such as OpenStreetMap and Natural Earth. It's a simple and to adopt OSM for displaying maps in your app, on your own storage.
You can download a daily build at maps.protomaps.com/builds.
I also maintain a hosted version of the Protomaps basemap on Cloudflare, free for non-commercial use. You can sign up for an API key here. This is useful if you don't want to maintain a copy of a part of the world on your own storage. Commercial use of this API requires becoming a Sponsor, which helps me pay for the infrastructure costs. However, the Protomaps business model is explicitly not SaaS; that would change the incentive structure, and distract the focus from making the map as simple to deploy as possible.
