# Developer API

## Developer APIs

> *Developer APIs enable developers to create advanced flight modes outside of the flight stack.*

## Drone Application Development SDK

> This SDK should allow developers to create drone “applications” that can run on mobile devices (tablets, phones) and on-board companion computers, and that can also seamlessly integrate drones with cloud-based services. The SDK should ideally support Python, C++ and Android Developer APIs, including options like ROS, Cloud etc., and also integration with any simulation environment.

Mobile SDK

* DJI
* Parrot
* FlytOS
* DroneKit

OnBoard SDK

* DJI
* Parrot
* FlytOS
* DroneKit
* AirLib, Microsoft AirSim

## Robot Operating System (ROS)

> ROS is a partner/complementary project of Dronecode that delivers a set of software libraries and developer tools for building and simulating robot applications. PX4 can integrate with ROS via two different APIs — either where native PX4 applications are ROS nodes or where ROS nodes communicate with PX4 via MAVLink (using mavros, a MAVLink to ROS gateway, with UDP proxy for Ground Control Station).
