GazePlotter vs GazeRecorder

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.

GazeRecorder uses a webcam to track eye movement and create video recordings for remote UX research on desktop and mobile. Its online service can test live websites, images, screenshots, mockups, pictures, videos and apps. The maker says it can show where participants look and for how long in real time. GazeFlow generates heatmaps over webpages, applications, static images or videos, and can combine data from multiple subjects. Desktop features include real-time webcam tracking, one-click experiment creation and dynamic heatmaps. The desktop version requires a webcam, but specialized hardware is not required; smartphone tracking uses the selfie camera. Visualizations include heatmaps, gaze paths, fixation metrics and areas of interest, with video recordings and session data available for export. The maker says respondent-level eye and click data can be provided along with aggregated sample data. The free desktop version is for non-commercial use. The FAQ gives approximate GazeCloud API accuracy of 1.0 degree and precision of 0.2 degree of visual angle. Listed platforms include web, Windows, iOS, Android and API.
