GazePlotter vs RealEye

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.

RealEye is a cloud-based webcam eye-tracking research platform for building online studies, tracking participants, and analyzing results. Researchers can use images, videos, or live websites as stimuli, configure display settings, and add instructions and follow-up questions. The dashboard includes heatmaps, gaze and fixation analysis, Areas of Interest statistics, survey answers, and raw or processed data exports. A facial coding feature analyzes neutral, happy, and surprised expressions. External survey connections can redirect participants to services such as Qualtrics, Google Forms, or SurveyMonkey and pass participant identifiers through URL parameters. RealEye says webcam image and sound processing happens in the browser, and that it stores gaze-point predictions rather than webcam images or sound. It states that it is GDPR compliant and runs on AWS data centers in the United States. Participants using a researcher's own link need a laptop or PC with a webcam; smartphone tests are also offered. Basic costs $325 a month billed annually or $390 a month. Standard costs $825 a month billed annually or $990 a month.
