PX4 is an open-source autopilot flight stack for drones and unmanned vehicles, supporting multirotors, fixed-wing, VTOL, rovers, and other platforms. It runs on NuttX, Linux, and macOS, with MAVLink and DDS/ROS 2 integration, SITL simulation, and broad Pixhawk hardware support.

Use cases

• fly a drone with open-source autopilot firmware
• build a custom quadcopter flight controller
• integrate ROS 2 with a drone for autonomous navigation
• simulate drone flights in software before flying hardware
• control a fixed-wing UAV or VTOL aircraft
• develop autonomous rover or boat control software
• do academic research on drone control and avoidance

When to choose

• you need a production-proven, vendor-neutral autopilot with wide hardware support
• you want MAVLink or ROS 2/DDS integration for offboard control
• you need simulation and hardware-in-the-loop testing tooling
• you want a BSD-licensed stack governed by the Linux Foundation

When to avoid

• you need a simple hobby flight controller with minimal setup
• your project targets non-drone robotics unrelated to unmanned vehicles
• you require a permissively-embedded stack for microcontrollers outside the Pixhawk ecosystem without porting effort
