GazePlotter is a free web application for eye-tracking data analysis and visualization. Its core goal is to turn complex gaze data into interactive scarf plots, transition matrices, AOI metrics, and other outputs. It emphasizes open science: no registration, no ads, no subscriptions, and data is not sent to a serverβall processing happens locally in the browser.
In terms of functionality, GazePlotter supports scarf plots/sequence charts, Bar Plots, Transition Matrices between AOIs, and Time-binned AOI Occupancy. It also offers drag-and-drop workspace management, chart copying and moving, participant group comparisons, and customizable AOI colors and names. Data compatibility is one of its strengths: the documentation lists support for Tobii Pro Lab, SMI BeGaze, OGAMA, GazePoint, Varjo XR, Pupil Cloud, Custom CSV, and GazePlotter workspace JSON imports. For export, it supports workspaces, aggregated data, and segmented data, and mentions integration with ScanGraph.
The tool is open-sourced under the GNU GPL v3 license. The text mentions a code repository, npm Package, and the ability to integrate it into Svelte projects. It is also a Progressive Web App, usable through a browser on Windows, Mac, Linux, and mobile devices. It can also be installed as a desktop app and run offline. The crawled content does not clearly describe a standard self-hosting setup, but there are references to download options and development build documentation.
Pricing is very straightforward: free, with no registration and no subscription. The documentation covers Getting Started, data upload, formats for each data source, basic charts, AOI customization, exports, advanced data workflows, and development builds. The structure is fairly complete and friendly for researchers getting started.
Its advantages are strong privacy protection, being free and open source, offline availability, and support for multiple mainstream eye-tracking platforms. It is well suited to research reproducibility, classroom teaching, and lightweight analysis presentations. Its limitations are that it is a vertical-domain tool rather than a general-purpose development platform; information on commercial support, SLA, enterprise collaboration, and payments is missing. It is best suited for eye-tracking researchers, students, and users who need to quickly generate visualizations from Tobii, SMI, GazePoint, Varjo, or Pupil Cloud data.
The crawled text does not provide information on network accessibility from mainland China, mirrors, or payment options, so this remains unknown. Since the app can be downloaded and run offline, users may consider using a local version if the website or code repository is unstable. Alternatives include Tobii Pro Lab, SMI BeGaze, OGAMA, Pupil Cloud, or analysis tools provided by the respective device vendors.
