wyvern builds.sr.ht status

Wyvern is a command-line tool written in rust that is meant to make downloading GOG games and associated activities easier and faster on linux. It features:

  • Downloading games

  • Installing games without need for the graphical installers

  • One-command updating of games to their latest versions, while only updating files that have changed between versions.

  • GOG Connect functionality so you can scan for and claim games without leaving the terminal

  • Syncing save files to a filesystem backup(with integration with cloud services being worked on).

  • Optional(compile with the 'eidolonint' feature) integration with eidolon, so that it automatically registers installed games to eidolon.

The GitHub repo is a mirror of the main sr.ht repository.

Wyvern is available on crates.io, installable via cargo:

cargo install wyvern

There's also a few other ways to get wyvern:

git clone https://git.sr.ht/~nicohman/wyvern && cd wyvern

cargo install --path . --force


Wyvern has a few extra dependencies, but few are required:

  • rsync for save file syncing
  • innoextract for windows game installation
  • unzip for faster game installation
