Nucleon-nucleon (NN) potentials from chiral EFT have entered the precision era with a χ 2 /datum ∼ 1 description of NN scattering data and can provide an alternative to existing partialwave analyses. The framework does not only allow for a model-independent and systematically improvable description of isospin-invariant nuclear forces, but also makes it possible to systematically include and study isospin-breaking effects. We give an overview of the isospin-breaking NN potential up to N 4 LO and
