vtm VS openstreetmap-tile-server

You are correct, Valhalla is used for routing. Maps are rendered on the ELEMNT, BOLT and ROAM with mapsforge, BOLT2 with vtm. To look at map files there is cruiser cruiser (mapsforge) and cruiser-gl (vtm). Create updated maps with wahooMapsCreator. There is also some documentation how to add POI's or make a custom theme.

for an example. It's perfectly smooth. The application is closed source but the underlying renderer (VTM) is LGPL3. The renderer, https://github.com/mapsforge/vtm, is basically an OpenGL alternative for the mapsforge offline maps format and maintained by the same guy (the original mapsforge renderer is arguably a bit slow, struggling to hide its slowness behind cached tile bitmaps).

Author here: the docker project for the tile server allows setting up automatic syncing fairly easily:

I'm not sure about Nominatim or Valhalla's ability to auto-sync the latest changes, at least with the dockerized version, but it may be possible.

We're in the same boat using Mapbox, we've been debating leaving for the OpenStreetMaps container since we only use them for static images and map display. https://github.com/Overv/openstreetmap-tile-server

Our bill last year was $80k and honestly its right on the cusp of being worth the effort to switch.

My friend Alexander created an easy docker file[1] for an OSM tile server. I use it for nearly two years without problems.

I found this project on Github https://github.com/Overv/openstreetmap-tile-server .

Finally: https://github.com/Overv/openstreetmap-tile-server I haven't tried this one before, but it seems kind of cool, and seems to be what you're looking for?

I don't need to serve the whole country, but it's nice to have a little more than just Missouri, so I was pleased to find Protomaps. There are several other extract repositories, but this was the only one I found that let me define and export a custom region. For the actual generation and rendering of the tiles, it seemed easiest to use this existing docker project.

I think an easy to setup self-hosted vector/tile server could help increase adoption. I'am currently looking into replacing Mapbox with a self hosted solution. My last attempt ran out of disk space building the docker images (with european maps) from https://github.com/Overv/openstreetmap-tile-server. Haven't found the time to setup a larger VPS but this looks like a great project to get started.
