What are MapProxy and MapServer?
MapProxy
MapProxy is an open-source proxy for geospatial data that caches, accelerates, and transforms map services. It can combine and reproject WMS, WMTS, and tile sources for faster and offline-capable maps.
- Tile caching and acceleration
- Reprojection on the fly
- WMS and WMTS support
- Offline map seeding
MapServer
MapServer is a long-standing open-source platform for publishing spatial data and interactive mapping applications on the web. It renders maps on the fly from geospatial datasets and serves OGC web services.
- On-the-fly map rendering
- OGC web services
- Geospatial data publishing
- Mature and stable
