What are the best open-source GIS and science apps?
By GitHub stars, QGIS is the most popular (14,727 stars), followed by Shadowbroker and Stellarium. People often use these instead of ArcGIS and SPSS. Each page lists the platforms, license and last commit.
Which of these run on Windows, Mac and Linux?
18 of the 20 open-source GIS and science apps listed here run on Windows, 16 on macOS and 18 on Linux; on a Mac, the most starred is QGIS. 4 can be installed with a package manager such as Flathub, Homebrew, winget or Chocolatey.
Are these open-source GIS and science apps free?
Yes. All 20 use an open-source license (OSI-approved or FSF-free), so you can use, copy and change them for free.
How are these open-source GIS and science apps chosen?
Apps come from desktop awesome lists (Awesome Linux Software, awesome-mac, awesome-windows, awesome-electron and the media and file sections of awesome-cli-apps), more than 70 GitHub topics such as desktop-app, electron-app, tauri-app, gtk, qt, macos-app, pdf-editor, cad and remote-desktop, and a hand-picked list of flagship apps. An app is listed only if it has a license (one GitHub detects, or one appsgit checked by hand), a README and a commit in the last six months, is not archived or a fork, and has 1000+ GitHub stars (topics), 500+ (awesome lists) or 100+ (hand-picked). It must also be an end-user application with a desktop signal: installers in its releases, install instructions for Windows, macOS or Linux, or a Flathub, Homebrew, winget, Chocolatey, Snap or AUR package. Libraries, frameworks, themes, plugins and servers are left out, and source-available apps are labelled as such.
