The Farama Foundation maintains a number of other projects, most of which use Gymnasium. Topics include: multi-agent RL (PettingZoo), offline-RL (Minari), gridworlds (Minigrid), robotics (Gymnasium-Robotics), multi-objective RL (MO-Gymnasium) many-agent RL (MAgent2), 3D navigation (Miniworld), and many more.
This page contains environments which are not maintained by Farama Foundation and, as such, cannot be guaranteed to function as intended.
If you’d like to contribute an environment, please reach out on Discord.
