Caasi is a lightweight, CLI-first orchestration layer for NVIDIA Isaac Sim, Isaac Lab and the wider robotics ecosystem (ROS 2, Nav2, MoveIt 2, ros2_control, …). It discovers the tools you already have, launches them headlessly, tracks every long-running process as a first-class run, and gives you uniform, scriptable output for all of it.
