Pupil is an open source eye tracking platform consisting of applications (Pupil Capture, Player, Service) that work with Pupil Labs wearable eye tracking hardware. It is written in Python and C++, offers a network-based real-time API, and supports runtime plugins for extensibility.

Use cases

• run eye tracking studies with wearable hardware
• record and replay gaze data from eye tracking sessions
• integrate real-time gaze data into my application over the network
• develop custom plugins for eye tracking analysis
• analyze fixations, blinks, and pupil diameter from recordings
• build a low-cost hackable eye tracker for research

When to choose

• you use Pupil Labs Pupil Core hardware and need capture/playback software
• you need an open source, extensible eye tracking platform with a real-time API
• you are a researcher conducting gaze or pupillometry studies

When to avoid

• you need eye tracking on ordinary webcams without Pupil Labs hardware
• you need arm64-native macOS support or a fully turnkey commercial solution
• you want a cloud-based analysis pipeline rather than local software
