GazePlotter vs Smart Eye Pro

GazePlotter is a free tool for researchers and non-programmers to visualize eye-gaze data without writing code. Its analysis options include scarf plots, AOI comparisons and timelines, transition matrices, recurrence plots, scanpaths, scanpath similarity, metric timelines, and metric correlations. The metrics library covers dwell time, fixation duration and counts, latency, AOI transitions, recurrence, scanpath similarity, and eye-movement types. It imports formats from Tobii Pro Lab, SMI BeGaze, Gazepoint, Pupil Cloud, Varjo, OGAMA, and custom CSV files, detecting file types automatically. Workspaces can be exported as JSON, figures as PNG or JPG, and segmented data, events, and metrics as CSV; ScanGraph export is also available. Metric CSVs can be exported in long or wide form for use in R, Python, SPSS, JASP, or jamovi. The maker says data is processed locally in the browser, and documentation describes an offline-capable Progressive Web App. It is listed for web browsers, Windows, macOS, Linux, Android, and iOS, and is open source under GNU GPL v3.
