# RudderStack Assistant


**RudderStack Assistant** is a browser extension for [Google Chrome](https://chromewebstore.google.com/detail/rudderstack-assistant/mldkpbdooncodocccgjjkjojkneohnif) and [Mozilla Firefox](https://addons.mozilla.org/en-GB/firefox/addon/rudderstack-assistant/) that helps you monitor, debug, and validate your RudderStack JavaScript SDK implementations directly within your browser.

Whether you're implementing event tracking for the first time or troubleshooting issues in production, this extension provides real-time insights into your SDK configuration and event flow.

## Key features

RudderStack Assistant automatically detects the RudderStack JavaScript SDK on web pages and provides the following capabilities:

- **Real-time event monitoring**: Monitor all events sent through RudderStack in real-time without waiting for the events to reflect in the RudderStack dashboard
- **SDK configuration visibility**: View the source write key, data plane URL, SDK version, and installation details
- **Destination status**: Monitor device-mode destination loading status (loaded, failed, or filtered)
- **Plugin tracking**: Track plugin loading status and identify failures
- **Load options inspection**: Inspect the options passed to the SDK's `load()` call, including user overrides and all active defaults
- **Debug data export**: Export comprehensive SDK state and events for sharing with support
- **SDK injection**: Test RudderStack on any webpage without modifying code
