Moonlander is the fanciest Gemini client in the entire solar system.

Note: Moonlander is still under development. While most features work well enough, issues might happen.


  • Custom, themeable rendering engine via Cairo & Pango
  • Tries to follow Gnome HIG

#Known Bugs

  • TLS Certificates aren't verified
  • Somewhat high resource usage (for a Gemini client)
  • Cannot navigate backwards through redirections
  • Renderer doesn't behave "native"
    • Cannot select/copy text
    • No interaction other than mouse clicks on links and scrolling

#Planned Features

  • Tabs

  • Render more than just text/gemini and plaintext.

    • Planned: Markdown & images
  • Possibly support other protocols

    • Gopher, etc.
    • Definitely not HTTP, unless excluding HTML
  • Syntax highlighting (?)

    • Waiting on text/gemini preformatting annotations to be somewhat standardized


git clone https://git.sr.ht/~admicos/moonlander
cd moonlander

cargo build --release

cd target/release
strip -s moonlander # optional, reduces file size by ~50%


  • GTK 3
  • Cairo
  • Pango
  • A new-ish Rust compiler

See Gtk-rs Windows requirements


Run Moonlander for the first time to create the configuration defaults.

  • Windows: %APPDATA%/ecmelberk/moonlander/config.toml
  • Linux: $XDG_CONFIG_HOME/moonlander/config.toml ($XDG_CONFIG_HOME is $HOME/.config under most cases)
  • macOS: $HOME/Library/Preferences/com.ecmelberk.moonlander/config.toml


If you want to embed Moonlander's rendering engine in your own application, see the moonrender directory. If your application uses relm, you can use relm-moonrender.
