No. We no longer want to bother with monthly updates and the overhead of maintaining our own tile server over <30€/month. We tried to make our own raster tile server several years before vector tiles were a thing, using tilecache, then tilestache and just gave up because of the storage and hardware requirements. Plus there's a lot of work involved in customizing your maps - we didn't want to show the standard OSM map built for mappers in mind but a transport oriented map for fleet tracking. MapTiler has almost everything we want except good Africa coverage.

Makes sense, thanks for your explanation.
