Analyze past user journeys instantly. Ask new questions of historical data without prior planning.
Uses custom, event-based tracking. If it wasn't tagged ahead of time, that data was never captured.- Felix Agentic quantifies impact automatically, but requires extensive event tagged in advance.
- Frequent script updates require ongoing review, trapping developers in a maintenance cycle, slowing time to action.

See why users drop off, not just where
Fullstory
StoryAI agents proactively surface frustration signals, drop-offs, and funnel anomalies, complete with quantifiable business impact, embedded directly within the platform or via MCP. Teams get the reason behind user behavior without starting from scratch.
Quantum Metric
Felix AI, built on Google Cloud's Gemini models, focuses on summarizing sessions and quantifying the impact of known issues. Its insight is limited to what's already been identified, leaving gaps in coverage for anything outside that scope.
One snippet, zero maintenance overhead
Fullstory
Fullstory uses Fullcapture to automatically record every interaction from a single snippet or SDK, adapting instantly to site or app updates. Teams never re-instrument, and engineering time stays focused on building rather than maintaining tags.
Quantum Metric
Quantum Metric relies on custom, event-based tracking that requires an ongoing tag management strategy. Frequent script updates demand additional review for performance and security, creating a continuous maintenance cycle.
Ask tomorrow's questions of yesterday's data
Fullstory
Fullcapture records every interaction from day one, so teams can ask a brand-new question and look straight back at historical behavior. No tags set up in advance, no waiting for data to pile up. The unknown unknowns are already there.
Quantum Metric
Event-based tracking only holds what was configured before the fact. A new question means new tags, then a wait for data to accumulate, so the unmeasured past stays a blind spot.

“Nobody wants to use it, nobody likes to use it."
"One of the issues that we have with Quantum Metric is, you know, nobody wants to use it, nobody likes to use it."
Marketing Manager, Fintech
“[Quantum Metric] had to do everything... it was really long lead time."
“If we wanted to change, we wanted to retarget an element, we would have to wait for them to go in and say we want to target this button instead of this one, or a class name change, something as simple as that.”
