flogtool

Turn ArduPilot .bin and MAVLink .tlog flight logs into shareable HTML reports — with anomaly flags.

Sample report →

What it does

$ flogtool report flight.bin
wrote flight.html
wrote flight.kml

You get:

• Hero card — duration, distance, max altitude, top speed, frame
• Map — flight path on Leaflet (OSM tiles)
• Flags panel — six anomaly heuristics (altitude drop, GPS glitch, vibration, RC loss, battery failsafe, crash) — see docs/anomalies.md
• Charts — altitude, speed, battery, vibration, GPS quality (synced time axis)
• Mode timeline — every flight-mode segment with duration
• KML companion — opens in Google Earth Pro

The HTML is fully self-contained — recipients open it offline; only the basemap tiles need internet.

Install

# Recommended
uv tool install flogtool

# or
pipx install flogtool

Or grab a single-file binary from Releases.

Usage

flogtool report <log>          # generate <log>.html and <log>.kml
flogtool report <log> --open   # ...and launch in browser
flogtool inspect <log>         # quick stdout summary, no files written

Supported formats

• ArduPilot .bin (DataFlash)
