Solution

Stop Chasing Ghosts. Start Fixing Code.

The session replay tool that speaks your language. We capture the technical evidence so you can spend your time fixing code, not chasing ghosts.

Designed for your workflow

Every fetch request, XHR response, and console.error is captured and synced to the timeline. No more asking users for HAR files.

Turn a bug report into a Playwright or Cypress test with one click. We pick stable selectors that survive your next refactor.

Our DOM serialization engine ensures the replay is a perfect reconstruction of the state, not just a video recording.

Watch the exact state transitions that led to a race condition or a hydration mismatch.

Impact: Reduce mean-time-to-resolution (MTTR) by 70%.

See Core Web Vitals in the context of a real user session. Identify the specific script slowing down the TTI.

Impact: Optimize the paths that actually matter to your users.

Does it work with React/Angular/Vue?

Yes. Relyv works with any framework that renders to the DOM. It captures Shadow DOM and custom elements out of the box.

How heavy is the SDK?

The SDK is under 40kb gzipped and runs off the main thread. It has sub-3% impact on page performance.
