GazePlotter vs Hawkeye

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.

Hawkeye is an eye-tracking tool for examining how people look at websites, images, and prototypes. It is software-based and does not need dedicated eye-tracking hardware, though its iPhone and iPad app requires a TrueDepth camera. Users can test websites and images without code changes, and the tool supports prototypes made with InVision, Marvel, and Sketch. Results show where participants looked and for how long through heat maps, screen recordings, and focus-point diagrams. Hawkeye can aggregate results across testers and provide statistics for individual interface elements. CSV exports include eye position, UI element, and touch data. Participants can be invited by text message using their phone numbers. Calibration centers the user's head, verifies calibration, and reports a five-star rating and accuracy estimate. Sign-in is available with Slack or Google, and company Slack teammates are automatically added to the same team. The free plan includes one project and five sessions; the Starter Plan costs $39.99 per month, billed monthly. Hawkeye runs on iPhone, iPad, and the web.
