# Session Replay Browser Dev Tools

## Overview{% #overview %}

Dev Tools is a built-in debugging panel in Session Replay that can help you troubleshoot issues in your applications. Use it to identify issues, trace requests, and understand performance bottlenecks—all without reproducing the issue yourself. Dev Tools are only available for [RUM](https://docs.datadoghq.com/real_user_monitoring/explorer/) sessions that have been retained. You do not need to configure anything to use Dev Tools.

## Dev Tools{% #dev-tools %}

To access Dev Tools, click the **Dev Tools** button in the Session Replay view. The **</> Dev Tools** button appears to the right of the **Share** button. You can view performance data, console logs, errors, and attributes about your replays.

### Performance{% #performance %}

The **Performance** tab displays a waterfall of events (such as actions, errors, resources, and long tasks) and timesteamps in a session.

Select and apply filters such as Action Name and Resource Type to change the scope of resources and event types displayed. You can also drag and drop the sliders in the waterfall to expand the time range.

### Console{% #console %}

The **Console** tab displays all [logs collected from the web browser](https://docs.datadoghq.com/logs/log_collection/javascript/) and errors for each view.

Click **Error**, **Warn**, **Info**, and **Debug** to filter your logs based on severity. To search for these logs in the [Log Explorer](https://docs.datadoghq.com/logs/explorer/), click **View in Log Explorer**.
