Open Source TypeScript Drone Software

ExpressLRS Configurator is a free, open-source, cross-platform application for configuring and building firmware for the ExpressLRS radio control system. It provides a graphical interface that simplifies preparing firmware for compatible radio transmitters and receivers. Users can select their hardware targets, choose firmware versions, and customize configuration settings before building firmware. The application supports device-specific options, including regulatory domains, binding phrases, and network settings. It helps streamline firmware installation and updates across supported ExpressLRS hardware. By organizing configuration and build processes into a single interface, it reduces the need for manual development tools and complex commands. ExpressLRS Configurator is designed for drone pilots, RC enthusiasts, and technicians who need to maintain reliable and customizable radio communication systems.

Betaflight App is a free, open-source configuration and management application for flight controllers running Betaflight firmware. It provides a graphical environment for configuring drones and other supported aircraft without manually editing firmware settings. Users can adjust flight characteristics, receiver inputs, motor configurations, and onboard system parameters. The application includes tools for tuning PID controllers, configuring flight modes, and adjusting filtering settings. It also supports firmware flashing, sensor calibration, and diagnostic monitoring of connected flight controllers. Betaflight App is available as a Progressive Web Application and as standalone software for multiple operating systems. Designed for FPV enthusiasts and drone builders, it simplifies flight controller setup, troubleshooting, and performance optimization.

OPEN DRONELOG is a local-first application for importing, organizing, and analyzing drone flight logs. It supports DJI flight logs, Litchi CSV files, Airdata exports, and optional custom parser plugins. DuckDB powers large-scale telemetry analysis with automatic downsampling for responsive charts. Interactive maps provide 3D flight paths, terrain views, replay controls, joystick visualization, and synchronized telemetry. The application tracks batteries, maintenance, tags, media captures, flight statistics, and pilot-specific profiles. Data can be exported to CSV, JSON, GPX, KML, reports, and shareable flight cards. It is available as a Tauri desktop app, self-hosted Docker web app, and limited browser-based viewer.
