See exactly what the user did before the failure.

A recording of the real user session

Session replay captures the DOM mutations, clicks, scrolls, and navigation that happened in the browser. You watch the session like a video, but it is reconstructed from the actual DOM events, not a screen recording.

Context for the crash, not just the stack trace

A stack trace tells you where the code failed. A replay tells you what the user was doing when it failed. Combined with logs and performance signals, it fills the gap that crash tools alone cannot cover.

Masking designed for sensitive fields

Vestara is designed to mask password fields, text inputs, and sensitive fields so replay captures structure and interaction without exposing unnecessary private values.

Reduce private data exposure

Sensitive elements can be marked with data-sensitive, and masked content is stripped before replay data is sent. The goal is to keep debugging context useful without collecting unnecessary private values.

Network call context

Replays capture the timing and sequence of API calls, fetch requests, and resource loads alongside user interactions.

Crash reports miss the user story

A stack trace shows the line of code that failed. It does not show that the user clicked the wrong button three times because the UI was unresponsive, or that they navigated back and forth before hitting the error.

Reproducing the bug takes too long

Developers often spend hours trying to reproduce a bug reported by a user. Session replay lets you jump straight to the exact sequence of interactions that triggered the failure without replaying the entire flow from memory.

Privacy controls matter

Many teams avoid session replay because they worry about capturing sensitive data. Vestara is designed to mask sensitive inputs and strip marked content before replay data is sent, helping teams keep useful debugging context while reducing exposure.
