AI Insights & Alternatives

Description

A comprehensive overview of this resource

The PostHog session recording script observes and records user interactions, including clicks, scrolls, keyboard input (with sensitive data masking), and DOM changes on a web page. It captures a sequence of events and snapshots of the page's structure over time, sending this data to PostHog servers. This allows website administrators to visually replay user sessions, reconstruct user journeys, identify usability issues, and understand how users navigate and interact with their site in real-time or historically. The script runs entirely in the browser, minimizing impact on server performance.
