Best open-source PX4-compatible drone simulators (2026)
These simulators let you test drone autopilot, perception and autonomy code in a virtual environment before flying real hardware. When choosing one, check the underlying engine (Unreal Engine or NVIDIA Isaac Sim), how it connects to PX4 and ArduPilot, and whether its APIs suit your research. Microsoft's AirSim has the most stars and covers drones, cars and other vehicles on Unreal Engine. PegasusSimulator runs on Isaac Sim and focuses on multirotors with PX4 and ArduPilot integration. aerial-autonomy-stack is built on ROS2 and targets perception-based drone swarms across PX4, ArduPilot and Betaflight.
