The screen flickers, and every click, scroll, and keystroke is replayed exactly as it happened. That is the power of a Proof Of Concept Session Replay.
A proof of concept validates that your session replay implementation works before committing full-scale adoption. It surfaces the truth about how users interact with your application, which errors occur, and how fast issues can be reproduced. Engineers rely on session replay to see the actual path a user took, not just the final state logged in analytics.
The first step is capturing the raw event stream: DOM changes, mouse movements, network requests, and console logs. For a proof of concept, keep the scope small but precise. Focus on a single flow—login, checkout, or form submission—and instrument only what you must, such as click tracking, viewport position, and request payloads. This lowers the implementation overhead and isolates performance impact.
Once data capture is defined, use a lightweight replay viewer. The goal is fast iteration. If the replay is slow to load, lacks timeline controls, or misses vital events, it fails the proof. A good session replay shows the sequence in real time and allows scrubbing, filtering, and network event correlation. Pair this with error monitoring to map front-end exceptions directly to replay sessions.
