FullStory is a digital experience intelligence platform that records every user session. It captures clicks, scrolls, and page transitions visually. But that comprehensive recording comes with trade-offs — a heavy script (~70KB), privacy concerns with visual recording, and enterprise pricing that requires a sales call. Happenstance captures the same interactions as structured data events in a ~8KB script.

Why teams switch
Teams explore alternatives to FullStory because of script weight impact on performance, privacy concerns around recording user sessions, and opaque enterprise pricing. Happenstance gives you the event data without the visual recording overhead — lighter, faster, and more privacy-friendly.
How to migrate from FullStory
- 1 Add the Happenstance script tag — structured event capture starts immediately.
- 2 Compare the automatically discovered events with FullStory's captured interactions.
- 3 Decide if you still need session recordings or if structured data is sufficient.
- 4 Remove the FullStory SDK to improve page load performance.
- 5 Save on both cost and page weight.
