Licences
Open-source licences.
Mosaik stands on a lot of open-source work. Here's what it uses, and under which licences.
Mosaik's own code isn't open source, but it's built on a lot of open-source work, and we're
grateful for it. This page lists the main parts. The full list, with every licence text in
full, comes with the app: it's THIRD-PARTY-NOTICES.txt in the install folder, and
Settings › About and updates opens it.
Qt and Qt for Python
Mosaik's window is built with Qt 6 and Qt for Python (PySide6 and Shiboken6), used under the GNU Lesser General Public License v3. The interface is drawn by Qt WebEngine, which includes Chromium and its own third-party components under their licences, listed in Qt WebEngine's licensing page.
- The Qt and PySide6 libraries are installed as separate files under
_internal\PySide6in Mosaik's install folder. You're free to replace them with your own compatible build. - Their source code is available from download.qt.io. We haven't modified them. If you'd like us to send you the source for the exact versions a Mosaik release uses, write to [email protected].
- The LGPL and GPL texts are included with the app.
