Neon
Neon is our most powerful eye tracker. It features research-grade gaze and pupil diameter estimation, industry-leading robustness in real-world applications, and a pleasant calibration-free user experience.
Pupil Invisible
Pupil Invisible was the world's first calibration-free eye tracker and set new standards for robustness in real-world applications. It is now deprecated and replaced by Neon.
Pupil Core
Pupil Core is a modular and more affordable eye tracker. It comes with open-source software and was the first eye tracker Pupil Labs created.

Real-time Visualizations
See what Neon is measuring by building real-time 2D and 3D visualisations of its data streams. Gain an intuitive feel for live metrics and learn how to integrate real-time data into your own custom applications.
Depth Estimation with Neon
Turn standard scene video into 3D gaze data using AI depth estimation in Neon Player. Visualize gaze depth heatmaps in your recordings and export frame-by-frame distance metrics!
Use Neon with Mentalab Explore Pro EEG
Use Neon alongside Mentalab EGG. Record Neon and Mentalab data into a single, synchronized file. Run a practical multimodal experiment using both systems.
