## What it is
Lagrange is a cross-platform desktop and mobile client for browsing Geminispace, written in C with SDL for graphics and OpenSSL for TLS. It offers browser-like conveniences such as tabs, bookmarks, history, identity management with TLS client certificates, and an optional curses-based TUI.

## Use cases
- browse gemini:// sites with a modern gui client
- read gemini capsules on windows macos or linux
- manage tls client certificate identities for gemini
- use a gemini browser on android or ios
- browse geminispace from the terminal with a tui
- listen to audio served over gemini
- access gopher and spartan content alongside gemini

## When to choose
- you want a polished, actively maintained gemini browser with tabs, bookmarks, and themes
- you need cross-platform support including mobile and a curses tui
- you value minimalism and a small dependency footprint
- you need identity management with tls client certificates

## When to avoid
- you need to browse the regular web (http/https)
- you need browser extensions or full web standards support
- you only need a simple command-line gemini fetcher
