In the context of indirect dark matter detection with charged cosmic rays and $\gamma$-rays, several public tools have been developed at LPSC (Laboratoire de Physique Subatomique et Cosmologie). I present a brief overview of these tools, namely USINE for the calculation of astrophysical nuclear fluxes and associated dark matter signals, the cosmic-ray database CRDB to retrieve cosmic-ray data and associated meta-data, and CLUMPY for the calculation of $\gamma$-ray and $\nu$ signals from dark matter structures. I stress the improvements made for the various releases of these tools. I then conclude with ongoing developments and a wish list for future releases. The main emphasis is put on the USINE code and the recent results obtained with it, as it was at the core of the presentation made at this workshop.
