New Relic Synthetics monitors your websites, critical business transactions, and API endpoints to measure optimal performance. New Relic Browser monitors the actual results of webpage performance across all variations of devices, browsers, and connection speeds. Used together, they provide a direct page load time comparison between real user (Browser) interactions and the Synthetics monitors.
Compare performance and trends
New Relic's comparative charting feature helps operations managers and teams by providing:
- Benchmarks for page load times
- Additional insights to help you plan where to optimize your site
- Comparisons of Synthetics trends vs. actual Browser performance without needing to switch between New Relic products
For example, during a page outage, you can compare Synthetics trends to actual Browser comparisons to see if an issue is also visible in Synthetics, or if it is caused by variables outside of Synthetics. This helps you more efficiently know where to take action.
The comparative charting feature requires:
- Browser Pro account with the Browser SPA agent (version 885 or higher).
- Synthetics Lite or Pro account using Synthetics a simple browser or scripted monitor with one or more tests on the same URLs monitored by the Browser agent.
After you enable the comparative charting feature either from New Relic Synthetics or from New Relic Browser, no additional setup is required. The comparative charting feature will appear when Browser finds matching URLs.

View comparison data
The comparative charting feature appears whenever Synthetics identifies a URL match with Browser and can compare it. You can compare Browser and Synthetics performance either from the Synthetics Overview page or from the Browser Page views page (for Browser apps or single page apps) without needing to switch between New Relic products.
Based on the selected data sources, the summary shows:
- Overall speed percentage comparison between Browser (real user) page views and any matching URLs found in Synthetics monitors that the user has permissions to view
- Number of URLs found in Synthetics monitors that match the Browser rollup URL
To view the comparative charting summary:
From Synthetics: Go to synthetics.newrelic.com > (select a monitor) > Overview.
From Browser: Go to rpm.newrelic.com/browser > (select a browser app) > Page views, then select a page monitored by New Relic Synthetics.
- Review the comparative charting feature's summary of overall speed percentage and number of matching URLs.
- To view additional details, select the summary's right arrow [right arrow icon] icon.
Hide or return comparison data
To hide the comparative charting feature, select the ellipsis [ellipsis icon] icon.
- To keep it visible but move it away from the top of the page, select Move to bottom.

New Relic uses these data sources for the Synthetics and Browser comparison in the UI. Some of these variables are calculated by New Relic Insights. For deeper analysis of the comparative chart data you see in the UI, use Insights to run NRQL queries.
