Session Inspector

The Session Inspector is accessible from the Dashboard by clicking a Session item.

This page provides all the tools to pinpoint possible problems like network issues, anti-bot mechanisms, or asynchronous events resulting in mismatches of selectors.

Session Replay and Metrics

A replay of each Session is featured in the Sessions page. This replay is a capture of the webpage, not a video, and can be inspected with your Chrome DevTools.

Here are some key takeaways:

• A high usage of memory or CPUs might result in longer runs and more billed minutes. Look at the logs or open a Live Session URL to pinpoint the root issue.
• In case of high proxy bandwidth usage, inspect the network requests using the Timeline described below.

Note that the replay length may not match the total session duration. This is because session timing starts when the browser begins running, while the replay recording only begins when the first page loads. The replay is a reconstruction of the DOM using rrweb events.

Live Mode

The Live Debug URL is a URL that can be used to inspect the Session in real-time.

This allows for human-in-the-loop debugging, and can be used to debug the Session in real-time.

The Copy Debug URL button is available in the Session Inspector only when the a live Session is running.

Status Bar

The Status Bar at the top of the Session Inspector displays the status of the Session, and the reason for termination if it has been terminated.

Here’s the information displayed in the Status Bar:

Property	Description
Session Id	The unique identifier of the Session
Status	The status of the Session, and the reason for termination if it has been terminated
Started	The date and time when the Session was started
Region	The region where the Session was run
Duration	The length of the Session
Proxy Bandwidth	The amount of data transferred through the proxy on the network tab (in MB)
Settings	The settings used for the Session (e.g. keepAlive or BrowserContext)

Replay

The Replay view makes it easy to inspect the actions performed (ex: select or click on an element) and network requests, page by page:

The replay controls allow you to:

• Adjust playback speed (0.5x, 1x, 2x, or 4x)
• Navigate to specific points in the playback timeline
• Pause and resume playback at any point

Events and Pages

The Events view displays the events and pages that occurred during the Session.

In the Events view, you’ll find:

• A list of pages that were loaded during the Session
• A list of current CDP events that occurred on each page (e.g. Runtime.*, Page.*, Input.*, and Log.* events)
• A list of network requests and responses that occurred during the Session

Logs

The Logs tab features the raw Chrome DevTools Protocol logs. The raw logs are rich, spanning over 2 main families of events:

DOM View

(DOM), describing in detail any actions and updates performed during Session

Console logs

Logs emitted by the Web Console API (ex: console.log()), making debugging remote Sessions as easy as using your browser

Some example of console logs:

• browser-solving-started
• browser-solving-completed
• browserbase-keeping-connection-alive
• Starting recording

You’ll also be able to see other logs as expected from a browser, like [DOM] Updated style of [body] or [Network] Request finished loading: GET "https://example.com/style.css"

Network events

Network events (Network), describing in detail any network requests and responses performed during Session

The Timeline also features logs emitted by the Web Console API (ex: console.log()), making debugging remote Sessions as easy as using your browser.

Logs can also be retrieved using the Sessions API for automated processing.
