RustGIS vs. QGIS

RustGIS vs. QGIS: which one should you use?

It's the question I get asked most about RustGIS, so we wrote a dedicated page that answers it honestly, including where QGIS is the better choice.

The short answer: RustGIS is not a QGIS replacement, and doesn't aim to be. QGIS is the mature, complete open-source desktop GIS, with 20+ years of development behind it. RustGIS is younger and narrower, but built differently.

Where RustGIS is stronger

• Tiny install: one native program written entirely in Rust, an 18-30 MB download with no Python, Qt or GDAL bundled.
• The whole app in your browser: not a viewer, the full GIS compiled to WebAssembly at web.rustgis.app, with your data staying on your device.
• Everything is a command: every button runs a command you can call from the CLI, Python, notebooks, the MCP server or the AI Assistant.
• A built-in AI Assistant that works through undoable commands, with your own model and key.
• Sandboxed WebAssembly plugins that run on the desktop and in the browser.
• Cloud-native data (COG, GeoParquet, FlatGeobuf, PMTiles, Zarr) read in place, even in the browser.
• A permissive Apache-2.0 licence, so its crates can be embedded in other software.
