Read any flight log, freeLog Analyzer
ArduPilot, PX4, Betaflight, INAV, DJI, Parrot and CSV logs, read in your browser. No account needed.
Reads a flight log: what the flight did and what to check. This is the log, not the diagnosis.
What it reads
ArduPilot dataflash (.bin), a MAVLink telemetry log (.tlog), a PX4 ULog (.ulg), a DJI flight record (DJIFlightRecord .txt), a Parrot FreeFlight log (.json), a GUTMA flight log, a flight-log CSV from Litchi, Airdata or a DJI GO conversion, or a Betaflight or INAV Blackbox log (.bbl, .bfl, .txt, or the blackbox_decode CSV). It tells you the aircraft and firmware the file came from, every mode change, event, error and autopilot message on one timeline, and the flight plotted out.
Your file waits in line, is held only until it is read, and is then deleted; the reading is kept for 7 days so you can leave the page and come back to it.

Flight map and 3D replay
The map and the 3D replay follow one timeline with the charts and the events below.
How the map works
The 2D map shows the track over the ground with every event in place: click any point, waypoint or event to see what the log recorded at that moment. The 3D replay shows the flight path in space, colored by altitude, with the aircraft posed from the log's own attitude. Play, scrub, or click a chart or an event row to move them; the ticks under the scrubber are the timeline's events.

Crash Analyzer
The Crash Analyzer reads this flight for causes: found in this log, signature not in this log, or not checkable from this log.
It needs the file again: this page deletes an upload once it is read.
Your organization does not have the Crash Analyzer. An organization admin can add it.

The summary goes to the address you enter: aircraft, firmware, flight time, mode changes, errors and battery.
