LEGWORK (LISA Evolution and Gravitational Wave ORbit Kit) is a simple package for gravitational wave calculations. It evolves binaries and computes signal-to-noise ratios for binary systems potentially observable with LISA; it also visualizes the results. LEGWORK can also compare different detector sensitivity curves, compute the horizon distance for a collection of sources, and tracks signal-to-noise evolution over time.

cogsworth merges rapid population synthesis and galactic dynamics together; the code can evolve a population of stars using population synthesis while self-consistently integrating their orbits with a chosen galactic potential. This enables exploration of the full evolutionary history (both stellar and orbital) of a population of stars and the ability to make predictions for present day kinematics and other distributions. cogsworth also provides tools for transforming the intrinsic populations into observables and for classifying the nature of each system.
