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.

Bioverse assesses the diagnostic power of a statistical exoplanet survey of the properties of nearby terrestrial exoplanets via direct imaging or transit spectroscopy. It combines Gaia-based stellar samples with Kepler-derived exoplanet demographics and a mission simulator that enables exploration of a variety of observing, follow-up, and characterization strategies. The code contains a versatile module for population-level hypothesis testing supporting trade studies and survey optimization. Bioverse supports direct imaging or transit missions, and its modularity makes it adaptable to any mission concept that makes measurements on a sample of exoplanets.

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.
