Wōtan provides free and open source algorithms to remove trends from time-series data automatically as an aid to search efficiently for transits in stellar light curves from surveys. The toolkit helps determine empirically the best tool for a given job, serving as a one-stop solution for various smoothing tasks.

EPOS (Exoplanet Population Observation Simulator) simulates observations of exoplanet populations. It provides an interface between planet formation simulations and exoplanet surveys such as Kepler. EPOS can also be used to estimate planet occurrence rates and the orbital architectures of planetary systems.

GPS (Genesis Population Synthesis) develops population synthesis models. The code suite uses the Genesis database of planet formation models for small exoplanets (super-Earths and Mini-Neptunes). Although the codebase focuses on the Genesis models, aother models can easily be integrated with GPS. It computes the bulk compositions of the planets and simulates atmospheric loss and evolution to find the final states of the planets that can be observationally verified. GPS also offers tools to process and analyze the data from recent observations of small exoplanets in order to compare them with the models.
