Join us live for an immersive session, “Session Replay Basics: Confirm & Debug Web App Issues Faster”.  We’ll show you how to confirm and resolve even the most difficult-to-repro errors and performance issues.

You know those elusive issues that you spend hours trying to reproduce – looking at you, hydration errors. Sentry’s Session Replay is the only replay tool made for developers, recreating user sessions from your web app when an error occurs.

Watch to learn about Sentry’s Session Replay so you can confirm and resolve even the most difficult-to-repro issues in your JavaScript application.

This session covers:

- Setting up and configuring Replay - and why Session Replay is [private by default](https://docs.sentry.io/platforms/javascript/guides/nextjs/session-replay/privacy/?original_referrer=https%3A%2F%2Fwww.google.com%2F)
- Triaging and troubleshooting errors with non-illustrative stack traces
- [Identifying user frustration signals](https://blog.sentry.io/not-every-problem-is-an-error/) with Replay
- Why we made our Replay SDK [35% lighter](https://blog.sentry.io/session-replay-sdk-bundle-size-optimizations/)
