Some Udda apps use open-source libraries licensed under the GNU Lesser General Public License (LGPL). You have the right to get their complete source code, change it, and rebuild it. This page offers a copy of the same sources the shipped files were built from.

  • Every file comes with its digital fingerprint (SHA-256); check it after downloading.
  • Downloads are for site members. If you need the sources another way, contact the site administrator.
  • The text of every license is also inside the app, on the "Open-source licenses" screen.
