CubeTrek is a web application designed to visualize, share, and manage GPS tracks with a focus on outdoor activities in mountainous and hilly terrain such as skiing, mountaineering, mountain biking, and trail running.

Unlike traditional 2D tracking apps, CubeTrek renders your adventures in realistic 3D topography. It features TrekMapper to reveal your most frequented spots, a replay mode to relive activities interactively, activity matching to benchmark past performances, and comprehensive dashboards with calendar heatmaps and performance metrics.

CubeTrek supports importing FIT, GPX, and ZIP files, and can sync with third-party services like Garmin Connect, Polar Flow, and Coros. It is open source under GPL-2.0.
