We use maplibre and map tiler for the map tiles in the startup that I run. We switched to that from leaflet and I've been pretty happy with it. I might invest some time at some point in self hosting tiles. But honestly, map tiler is good value for money for now. I actually used to work with Nokia and Nokia Maps (in Berlin), which is now Here Maps. So, I know a thing or two about this market and still know some people working with various map companies, including at mapbox. Mapbox is increasingly an alternative to Here, Tom Tom and a few others that offer a wide range of services. The most simple one of which is showing maps. Think of indoor maps, traffic services, routing, geo coding, address search (surprisingly hard problem with open data), etc. Customers for these services tend to spend a lot of money on getting all sorts of bespoke solutions. Maps are a commodity at this point and there's very little money in providing just some basic maps. It's all the other stuff that's built on top of that that is a lot harder and more valuable. The recently announced overture collaboration could actually shake things up a little in this space. Openstreetmap is nice but also has some pretty significant limitations. Basically what the above mentioned companies do is creating proprietary services and data (with and without open data typically) that they then sell access to for a lot of money. The big companies behind overture are each big customers for this stuff. And now they are pooling resources to create a cheaper, more open alternative to all that.
