GazePlotter review
A capable free analysis workspace for imported eye-tracking data, not a recording platform.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GazePlotter is a free, open-source browser application for researchers, students, and professionals analyzing eye-tracking data without writing code. It focuses on visualization and analysis rather than gaze recording, accepting files from established eye-tracking platforms and custom CSV files. Its supported environments include web browsers, Windows, macOS, Linux, Android, and iOS, giving teams several ways to access the workflow.
The standout strength is the range of analysis views. GazePlotter includes scarf plots, AOI comparisons with dwell-time and fixation metrics, transition matrices, AOI timelines, scanpath and scanpath similarity analysis, recurrence plots, metric timelines, and metric correlation plots. Users can manage participants, AOIs, and workspaces, then export workspaces, figures, segmented data, event data, metrics, and ScanGraph sequences. That combination suits projects requiring more than a basic gaze overlay, especially when comparisons across areas of interest or participant behavior are central.
Its ecosystem fit is also practical: imports cover Tobii Pro Lab, SMI BeGaze, Gazepoint, Pupil Cloud, Varjo, OGAMA, and custom CSV files, with ScanGraph sequence exports. Processing happens locally in the browser, with no registration or server uploads required. GazePlotter is a strong choice for free, cross-platform analysis of existing hardware-captured data. Teams seeking an integrated recording environment, or users who only need a simple visualization, should choose a narrower or recording-focused alternative instead.
