Dev Tools helps you understand how page performance—speed and reliability—affects your customer experience. Open Dev Tools during session playback to view Console and Network information for any customer session, including console messages, errors, and network requests.
Dev Tools includes:
- Console - View console messages, warnings, and errors
- Network View - Inspect network requests and responses
In addition to Dev Tools, Fullstory captures page performance data and provides reports to help you understand performance across your site:
- Page Speed Metrics - View performance metrics for every page
- Slowest Pages - Identify pages with the slowest load times
Use Dev Tools to debug issues like…
- Which image, file, or script was causing my site to load slowly for this customer?
- What console errors did this user encounter?
- Did an API call fail during this session?
- How long did specific network requests take?
Console
The Fullstory Console allows you to capture messages reported in a customer's browser console. See console messages, warnings, errors, and uncaught exceptions that occurred during any session, giving you the power to see exactly what happened in a customer's browser without needing to replicate.
Learn more about using the Fullstory Console.
Network View
The Network view in Fullstory allows you to see line-by-line network requests as they happened in the browser to load a page.

Understanding page performance
Beyond Dev Tools, Fullstory captures the page performance data you need to understand and improve page performance across your site.
Page Speed Metrics
Fullstory automatically captures page speed metrics for every page that loads during any session. These metrics include timing milestones like DOMContentLoaded, First Contentful Paint, and Load Time.
You can view page speed metrics in several places:
- In the Events stream during session playback
- As search criteria in OmniSearch and Segments
- Within the Network view in Dev Tools
Together, these page speed metrics can help you understand whether a page was rendering or loading slowly for any individual user. And, because page speed metrics are available as search criteria for OmniSearch and Segments, you can layer these timings onto any of your funnels or Segments to learn more about performance in the context of specific pages or groups of sessions.

Slowest Pages
The Slowest Pages report shows you the slowest pages related to any search or segment, by First Contentful Paint. You can find Slowest Pages for any search or segment, and this report gives you excellent signal to understand where to improve your performance and also where you might want to search to find slow sessions.
The Slowest Pages report groups largest First Contentful Paint by Page. Fullstory automatically suggests page groupings to represent the logical pages in your app. If you're interested in learning more about Pages in Fullstory, check out our in depth article here.
