MTL Explorer quick intro video preview

MTL Explorer is an open-source tool for mapping your GPS history. It runs locally on your hardware, so your data stays private. You can load thousands of tracks, check your stats, and sketch out your next route.

Hosted demo instance with a sample archive.

What you can do with MTL Explorer.

Load up thousands of tracks on a single map. Switch the same archive between year views, activity types, photos, custom filters, and planning views.

How it works.

Set up the server, import your files, and start exploring.

1

Import your files

Drop files into a folder or import from Garmin. It supports GPX, FIT, TCX, KML/KMZ, IGC, NMEA, GeoJSON, and GDB.

2

Automated processing

The app indexes your files, removes duplicates, and spots bad data points in the background.

3

Map and analyze

Use filters to find what you want. Click tracks to check speed, distance, or mechanical energy spent.

4

Route planning

Draw point-by-point routes directly on the map. Save them as GPX files for your next trip.

Open source and self-hosted.

You control the server and the data. No external accounts are required to use the core tools.

Keep it local

All your GPS files and photos stay on your hardware. You do not have to share your history with anyone.

  • Open source (AGPL) with a commercial license option.
  • Runs in Docker. The API, database, and map tiles remain local.
  • Basic offline support. You can view cached tracks if you lose internet.
