Lagrange is a desktop GUI client for browsing Geminispace. It offers modern conveniences familiar from web browsers, such as smooth scrolling, inline image viewing, multiple tabs, visual themes, Unicode fonts, bookmarks, history, and page outlines.

Like Gemini, Lagrange has been designed with minimalism in mind. It depends on a small number of essential libraries. It is written in C and uses SDL for hardware-accelerated graphics. OpenSSL is used for secure communications.



On macOS you can install and upgrade via Homebrew:

brew install --cask lagrange

Please check MacPorts if you are using macOS 10.12 or older.

On openSUSE Tumbleweed:

sudo zypper install lagrange

On other platforms (e.g., *BSD), you'll need to compile the source tarball (CMake).
