Flags PyQt5/PyQt6 imports (GPL v3 or a paid Riverbank licence) and the PyQt-only APIs that break under LGPL PySide6: pyqtSignal, pyqtSlot, uic.loadUi, QRegExp, exec_, sip. One fix per line. Runs entirely in your browser — nothing is uploaded.
Free here: Every PyQt5/PyQt6 import and PyQt-only API in one .py file, each with its PySide6 replacement line. In the editor: The whole workspace in one pass plus an exportable migration report per file for release or licence sign-off — that part asks for a licence key.
Same engine as the VS Code extension, byte for byte.
