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. It also includes useful tools, such as connection details, optional DNS/Geo-IP features, flexible proxy configuration for use with modern IPv6 mesh networks like Yggdrasil, Mycelium, CJDNS, and others.

Yoda browser is primarily designed by and for experienced network users who care about their fingerprints and prefer to control every action manually. It does not preload tab content on app opening, does not run any background connections, does not incorporate web-like media preloading without user initiation, and does not automatically check for updates, even from 'official' servers. Additionally, it prevents auto-follow external redirection by default and requires manual confirmation, which is currently not clearly specified.

The Gemini protocol was designed as a minimalistic, tracking-resistant alternative to the Web, and Yoda embraces this philosophy by providing a straightforward graphical user interface (GUI) that is partially inspired by the Firefox UI, making it intuitively comfortable for regular users.

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
