The screen loads, and every move is already recorded. That is Phi Session Replay in action—your exact app state, every user event, perfectly reconstructed. No guessing. No blind spots.
Phi Session Replay captures the full story of every session with precision. It records DOM changes, network requests, user interactions, and console logs. Engineers can jump to any moment and see what the user saw, when they saw it, and what happened under the hood.
Unlike basic analytics, Phi Session Replay is built for deep debugging. You can trace issues from the surface down to the API call, match application state to timestamped events, and reproduce complex bugs without relying on user reports. Every session is indexed and searchable, letting you filter by error type, endpoint, or any custom event within seconds.
Performance is core. Phi Session Replay streams data efficiently so you can store and replay sessions at scale without crushing your infrastructure. It handles heavy front-end frameworks and dynamic UIs with minimal overhead, maintaining fidelity across browsers and devices.
