Teams can collaborate on maps in real time, share them, use threaded comments, and manage permissions. The Personal plan is free forever and allows unlimited maps and sharing, but it is for personal use and excludes uploads of your own data files. Professional and Enterprise are annual contracts with prices not published; Professional lists 25 GB monthly data processing and 100K monthly map views. A seven-day trial is listed. Felt supports web, desktop, mobile, API, and self-hosted platforms.
GRASS GIS
GRASS GIS is a geospatial processing system for raster, vector, and other geographic data, including terrain, ecosystem, hydrology, data management, and imagery work. It contains more than 500 modules for processing and rendering geographic data, with tools for 3D voxel, temporal, image-processing, and spatial-statistics tasks alongside raster, terrain, hydrological, and vector analysis. Through GDAL-OGR, it supports nearly all common GIS file formats. Interfaces include a graphical user interface, command line, C API, Python, Jupyter Notebook, and WPS. GRASS integrates with QGIS and R and provides PostgreSQL and SQLite database interfaces; its official Addons repository has more than 300 extensions. It is free and open source under GPL (>=v2), with no warranty. The listed platforms include Linux, macOS, Windows, API, web, and self-hosted deployment. Prebuilt macOS applications are signed and notarized. Support includes a worldwide community as well as commercial consulting, training, and custom development.
