The software framework underlying the NNPDF4.0 global determination of parton distribution functions (PDFs) is released under an open source licence and is accompanied by extensive documentation and examples. The code base is composed by a PDF fitting package, tools to handle experimental data and to efficiently compare it to theoretical predictions, and a versatile analysis framework.
