KFactory

KFactory is a Python library providing a high-level, Pythonic API for KLayout, a popular GDSII layout editor. It simplifies the creation and manipulation of GDSII layouts for chip design, acting as an abstraction layer over KLayout's native Python API (pya). It is often used in conjunction with `gdsfactory` for photonic integrated circuit (PIC) design. The library is actively maintained, with the current version being 2.4.6, and typically releases updates as new KLayout features are exposed or `gdsfactory` integration evolves.
