Browsers provides you with information about the browsers sessions are taking place on. These metrics help you to maintain support and testing coverage across all browsers.


You can view the percentage breakdown of application usage across different browsers at the top of the page. This is calculated based on the number of page views on each browser.

The average load times graph shows you the trend in average load time for the top browsers browser across the date range specified.

To switch the Y-axis into a logarithmic scale, use the checkbox in the top right-hand corner of the chart. This helps if the graph contains large timings that flatten the rest of the line.

The Top 50 browsers table displays the following metrics for each browser:

  • Page views
  • Anonymous users
  • Known users
  • Total users

The table can be sorted by clicking on any of the column headers.

To groups together different browser versions so you can view aggregate usage for a particular browser, click the settings cog in the corner of the table and select 'group browsers'.

You can still view the list of versions with grouping enabled, by clicking the plus button that appears on the left-hand side of the browser logo.

To export a CSV of the data in the date range selected, click the settings cog on the table and select 'Export CSV'. Note: Export CSV does not conform to filters, meaning data exported will not match any filter critieria applied.

Browser versions are provided to the most granular detail available. Please be aware that there may be some instances where we are not able to retrieve the exact browser version and sub versions might be clustered into the main version.

Starting with the release of Firefox 100 and Chromium 101 based browsers (Chrome, Edge, Opera), the details provided by the User-Agent String have been reduced.

Where possible we use the new User-Agent Client Hints API to retrieve the user's browser version. If the User-Agent Client Hints API is not available, we use the traditional method of extracting the browser version from the User-Agent String.

When possible Raygun will provide the exact browser versions with the format:

When only restricted browser versions are available the version will be presented in the format:


If you are seeing an unexpectedly high number of sessions with restricted browser versions this could have different reasons:

  1. You are using an older version of raygun4js NPM or Nuget packages. Please ensure that you have updated to the latest version.
  2. The user may have opted out of providing their exact browser version via the User-Agent Client Hints API
  3. The browser has opted out of providing the exact browser version (notably Firefox, which does not support the User-Agent Client Hints API)
