In this talk I will introduce PriNCe (Heinze et al 2019) as a novel open-source Python software for UHECR propagation. The computational efficiency of PriNCe allows the user to perform vast scans of the source parameters, the emitted spectral shape, and the mass composition. I then discuss recent applications of the code, such as the first joint fit to Auger and Telescope Array (TA) spectral and composition data. The fit favors the presence of a local source of UHECRs in the Northern Hemisphere at the 5.6$\sigma$ level compared to the scenario where both experiments observe only an isotropic source population. I comment on possible source candidates based on the predicted distance and mass composition.
