Features

• High-Performance Analytics: DuckDB-powered queries with automatic downsampling for large datasets. Free, open source, no subscription required.
• Multi-Format Support: Import DJI logs (.txt), Litchi CSV, and Airdata CSV exports with automatic unit detection. Third-party apps (Dronelink, DroneDeploy) supported. Optional external parser plugins can be configured via parsers.json.
• Smart Deduplication: Prevents duplicate imports based on drone serial, battery serial, and start time.
• Interactive Flight Maps: 3D terrain, map-type selection (Satellite, Topographic, OpenStreetMap), flight replay with speed control (0.5x-16x), live telemetry overlay, and RC joystick visualization.
• Telemetry Charts: Height, speed, battery, cell voltages, attitude, RC signal, GPS, distance-to-home, velocity, battery full capacity, and battery remaining capacity with synchronized drag-to-zoom, per-profile telemetry color customization, and collapsible panel controls.
• Local-First Storage: All data in a local DuckDB database. No cloud upload required (except DJI key fetch during first import).
• Smart Tags: Auto-tagging (Night Flight, High Speed, Low Battery, etc.) and offline reverse geocoding for location tags. Manual tags and bulk operations supported.on.
• Filters & Search: Date range (calendar + typed YYYY-MM-DD start/end quick entry), drone/battery/controller/color filters, duration/altitude/distance sliders, tag filter, map area filter, and filter inversion.
• Overview Dashboard: Aggregate stats, activity heatmap, pie charts by drone/battery/duration, time-of-day radial chart, cluster map with optional heatmap layer, and top-flight highlights.
• Battery Health: Per-battery health bars with cycle count tracking, serial renaming, per-minute usage history with zoom, and battery capacity history chart with multi-select battery dropdown showing full-charge capacity trends over time.
• Maintenance Tracking: Configurable thresholds with color-coded progress bars and date-based maintenance recording.
• Exports: CSV, JSON, GPX, KML, and Summary CSV export. FlyCard generator for shareable 1080x1080 social media images.
• HTML Report: Generate a configurable, print-ready flight regulation report (A4 layout) with selectable field groups, weather data, and day-by-day grouping. Can be printed as PDF via Ctrl+P. Pilot name and field preferences can be customized and will persist across sessions.
• Manual Flight Entry: Record flights without log files with optional coordinates and metadata.
• Multi-Language Support: Full internationalization with 11 language locales (English, German, Spanish, French, Italian, Japanese, Korean, Dutch, Polish, Portuguese, Chinese) and locale-aware number and date formatting.
• Progressive Web App (PWA): Optionally install the application directly from the browser for a native-like experience on desktop and mobile.
• Backup & Restore: Export/import full database across desktop and Docker instances.
• Profile System: Create multiple profiles to separate flight data by pilot, drone fleet, or purpose. Each profile has its own database, config, uploads, and sync folder.Optionally lock any profile (including the default) with a password.

Accessing flight log files

You first need to collect the supported flight log files that you can import to this application.

Automated Sync (Windows/Mac)

You can sync your DJI flight logs directly from the mobile (Android/iPhone) or RC/RC-2/RC-Pro directly and seamlessly using the Litchi Hub Bridge companion app on your Windows/Mac desktop or laptop. This is a free application that lets you sync your flight logs from the phone's DJI Fly app or the RC devices directly to a local folder.

Download Here - Windows | MacOS

After installation, run it and check the tray menu (it usually gets minimizedto tray after start) - Right click on tray icon and pick settings - Check the Start with Windows in General tab and go to Flight Logs Sync tab to pick a local folder where the logs will be synced. Select the Auto-sync when a device connects for a seamless experience. After this setup, as soon as you plug in your RC or Android/iPhone (should be unlocked and mounted to your desktop/laptop) which you use to fly your drones, it will automatically search for the relevant folders and copy the .txt logs from there to your selected local folder.

[!TIP] After you set up Open Drone Log, you will have an option to pick a Sync folder from where the application (Open Drone Log) syncs files on startup for new log files. If you select the same log folder for both application, you will not have to find or copy new logs manually anymore - it syncs automatically with your Oopen Drone Log application!

Manual Log collection

This project supports modern DJI log files in the .txt format. For DJI fly apps on Android or RC remotes, they are usually in Internal Storage > Android > data > dji.go.v5 > files > FlightRecord. For iOS, Connect your iPhone/iPad to a computer, open iTunes/Finder, select the device, go to the "File Sharing" tab, select the DJI app, and copy the "Logs" folder. If you are already using other online sync applications, you can download the original logs files directly from there too.

You can find more details resources from this simple google search

Litchi flight logs can be exported as CSV files from the Litchi app. Litchi-imported flights are automatically tagged with "Litchi" for easy filtering.

Airdata Exports

If you use Airdata to sync your flight logs, you can export the original DJI log files directly from the Airdata website:

1. Go to your Airdata flight logs and click on my account
2. In the left sidebar, under My Data secction, pick Download my data
3. Click Request Export and wait for their email with zip containing the .txt files

These exported log files can then be imported directly into Open DroneLog.

Setup and installation (Windows/MacOS)

There is no installation step if you want to use the standalone binary builds, just visit the latest release page, and download the appropriate binary for Windows or MacOS and run them.

[!WARNING] For macOS, there are additional steps required before you can use the application.

[!IMPORTANT] When you are copying from RC or mobile device, you can NOT directly drag and drop the files to the interface. This is because these external devices are mounted differently and only accessible to the file manager. Please copy the files to a local folder or the device sync folder before trying to upload or sync.

[!TIP] Explore the full manual if you want to have a comprehensive overview of all the available options and features inside the app.
