Understand every user interaction.
Session replay, product analytics, funnels, crashes, network and console, and performance — across web and mobile, in one platform. With AI that investigates across all of it to explain what changed and why.
Replay any session, pixel-accurate.
Every click, tap, page and screen — reconstructed from the DOM and native view hierarchy, not video. Scrub the timeline, jump to the exact moment an error fired, and read the console and network alongside the frame.
- Web and native mobile, one player
- Event timeline with rage-click and dead-click markers
- Automatic masking for PII, on by default
Measure what happens, then watch why.
Build funnels, retention and journeys from the same events that power replay — so every drop-off is one click from the sessions behind it. No separate SDK, no second source of truth.
- Multi-step funnels with per-step conversion
- Cohorts and retention on live event data
- Every drop-off links straight to its replays

Crashes and freezes, grouped and ranked.
Crashes, handled exceptions and UI freezes across releases and platforms — grouped by root cause, ranked by impact, and one click from the session where each one happened.
- Symbolicated stack traces, per release
- Impact ranking by affected users
- Jump from a crash straight into replay
The console and network, on the timeline.
Every console log, warning and error, and every network request with status, timing and payload — captured with the session and synced to the exact frame. Debug production from the outside in.
- Full request/response headers and bodies
- Errors correlated to the crash that followed
- Filter by status, method, duration
Everything the last four tools did, together.
Replay, analytics, and debugging share one event stream, one SDK, and one design — so a signal in any of them is one click from all the others.
Performance monitoring
Load, render and interaction timings per screen and release, tied to the sessions that felt slow.
User journey analysis
The real paths users take between screens — where they loop, backtrack and abandon.
Feature adoption
Who reached a feature, who returned, and which cohorts stuck — measured on live events.
Cohorts
Segment users by behaviour, properties or funnel step, then follow them across every surface.
Alerts
Get notified when a crash spikes, a funnel drops or a metric moves — routed to your channels.
User profiles
A single timeline per user — every session, event, error and identify() property in one place.
It doesn't replace analysis. It accelerates investigation.
Replayfy AI reads across sessions, errors, funnels, releases, performance, network and crashes at once — and connects them into a plain-language account of what changed and why. It shows its work: every claim links to the sessions and signals behind it.
