## What it is
Paparazzi is a free and open-source hardware and software suite for unmanned air vehicles, providing autopilot firmware, ground control station software, and simulation tools. It supports fixed-wing, rotorcraft, hybrid, and even surface vehicles, with a dynamic flight plan system for fully autonomous missions.

## Use cases
- build an open-source autopilot for a drone
- run autonomous missions on a fixed-wing UAV
- control multicopters with a ground control station
- simulate flights before flying real hardware
- program waypoint-based autonomous flight plans
- flash autopilot firmware onto supported boards

## When to choose
- you want a fully open-source autopilot stack with no vendor lock-in
- you need autonomous mission planning with dynamic flight plans
- you fly fixed-wing, rotorcraft, or hybrid vehicles of various sizes
- you want simulation support (JSBSim) to test before flying

## When to avoid
- you want a plug-and-play consumer drone experience
- you need commercial support or certification
- you primarily fly on Windows/macOS natively (Linux/Ubuntu is best supported)
- you want a minimal firmware-only solution without ground station tooling

## Facets
- artifact type: application
- maturity: active
- function: embedded, simulation, monitoring, gui, developer-tools
- domain: robotics, autonomous-vehicles, hardware, embedded-systems, simulation
- platform: windows, cross-platform, embedded
- tags: uav, autopilot, drones, ground-control-station, flight-planning, telemetry, open-source-hardware, linux, macos
