Lagrange

About

Lagrange is a cross-platform client for browsing Geminispace. It brings conveniences familiar from web browsers, including smooth scrolling, inline image viewing, multiple tabs, visual themes, Unicode fonts, bookmarks, history, and page outlines. Consistent with Gemini's minimalist design, it relies on a small number of essential libraries, is written in C, uses SDL for hardware-accelerated graphics, and uses OpenSSL for secure communications.

Features include typography with full Unicode support, an autogenerated page style and icon for each Gemini domain, smart URL suggestions drawn from bookmarks, history, and identities, and a sidebar for page outlines, bookmarks, identities, and history. Lagrange also offers multiple tabs and split view, TLS client certificate management, audio playback for MP3, Ogg Vorbis, and WAV, and a curses-based text interface as an alternative to the graphical one.

For Mac users, prebuilt binaries are available for macOS 10.13 or later on both arm64 and x86_64, and the app is listed in the Apple App Store. Help is available inside the app at about:help.
