It helps you understand the entire user journey from the first click to long-term retention. Because it is open-source and offers a self-hosting option, you maintain full control over your data privacy and compliance.

It provides a complete visual history of every user's journey, allowing you to watch replays of actual browsing sessions to identify bugs or UX friction points in real-time. You can build conversion funnels to track specific user paths and use heatmaps to see where people click most often.
