We present a first overview of aSuperIso_DM, a platform based on Mathematica and C++ that is dedicated to the computation of various dark matter observables in the framework of a quantum field theory that can be cast under a Lagrangian form and that features a dark matter particle. aSuperIso_DM generalizes the supersymmetry-specific program SuperIso Relic by relying on an interface to FeynRules to generate a C++ program dedicated to the model under consideration. This C++ code can then be used for calculations of the dark matter relic density and direct and indirect detection cross sections. aSuperIso_DM moreover offers the advantage to allow for alternative cosmological models (which contrasts with other similar public codes), for the visualization of (co-)annihilation Feynman diagrams and for the deriviation of explicit formulae for all relevant squared amplitudes.
