Lagrange
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.

- Autogenerated page style and Unicode icon for each Gemini domain

Known issues
Flatpak
Flatpak applications run in a sandbox that limits their access to the rest of the system. At the moment, Lagrange has not been fully adapted to use Flatpak Portal APIs, so the following are known issues:
- Unable to open HTTP/HTTPS links via the default browser.
- Multiple instances of the application overwrite each other's data.
