How QtPy is used
QtPy is a dependency in 1 of the 6,208 public GitHub projects set up for AI coding agents that we scanned, too few to describe it from them alone. Our scan also samples projects by dependency (Solana 2,661, Ethereum and EVM 1,496, 3D and games 2,818, agent frameworks and SDKs 10,983); counting those, it appears in 81 projects, and what it is used with below comes from all of them. The most used alternative in our scan is PySide6 (8 projects). Projects that use it most often also use jsonschema (98.8%), Pygments (98.8%), CFFI (97.5%).
