Yoda - Browser for Gemini protocol

Privacy-oriented GTK 4 / Libadwaita client written in Rust.

The term Privacy-oriented means that Yoda complies to the Gemini protocol specification and excludes third-party connections, that making it safe to use in combination with I2P. The Yoda browser also includes useful tools, such as flexible proxy configuration, out of the box for use with mesh networks like Yggdrasil, Mycelium, CJDNS, and others. Additionally, it prevents auto-follow external redirection by default and requires manual confirmation, which is currently not clearly specified.

Yoda browser is primarily designed by and for experienced network users who care about their network fingerprints and prefer to control every action manually. It does not run background connections, does not incorporate web-like media preloading without user initiation (unlike some other clients), nor does it automatically check for updates from unexpected network-related servers.

The Gemini protocol was designed as a simple, private alternative to the Web, and Yoda follows this philosophy by providing a graphical user interface (GUI) for seamless navigation in Geminispace, partially inspired by the Firefox UI.

Contributors

Localization

UI localization planed as Crowdin repository, but it is not implemented yet.

To install new spell dictionaries in Fedora, use sudo dnf install hunspell-CODE

• just replace CODE with the locale code you want

Geo-location

To enable geo-location features, get official IP database from MaxMind
then copy following files into the config folder (available from menu)

• GeoLite2-Country.mmdb
• GeoLite2-City.mmdb (not implemented yet)

Releases

• Package version in repository increase after crates.io release
• Until DB migration not implemented, application will create new profile on every CARGO_PKG_VERSION_MAJOR.CARGO_PKG_VERSION_MINOR change
