MapServer vs QGIS

MapServer has no write-up on Specifiction yet; its figures are above.

QGIS is free, open-source software for creating, editing, analyzing, visualizing, and publishing geospatial information. Its layout designer produces print maps, while reporting tools can assemble atlases and reports containing maps and tabular material. It includes hundreds of analysis tools and supports visual workflows that can be reproduced. QGIS works with many data sources and formats and can use or create web services based on industry standards. More than 2,000 community-developed plugins add capabilities. QGIS Server publishes projects and layers through OGC-compatible WMS, WMTS, WFS, and WCS services. The download page offers a Long Term Release for users who prefer stability over the latest features. The project lists third-party mobile field apps, including QField, Mergin Maps, and IntraMaps Roam; these are separate from QGIS mobile apps. QGIS is licensed under GNU GPL version 2 or later and has community support through forums, GIS StackExchange, chat channels, and local user groups. The free plan costs nothing.
