Real-browser testing to help you measure, visualise and improve the experience your website delivers


Faster websites mean better conversion, lower bounce rates, happier customers and, ultimately, more revenue. Optimising a website for performance can also cut bandwidth and infrastructure costs.

But to improve your website’s performance, first you need to understand it.

Performance Analyser uses real-browser performance tests to help bring you that understanding.

It can crawl your site, give you a picture of overall performance, identify the worst performing pages and even offer optimisation advice.

Performance Analyser also gives you insights into perceived performance, with metrics such as Speed Index and visualisations such as the Performance Heatmap.

  • Reliably benchmark performance – thanks to NCC Group’s uniquely stable testing platform, you can test, improve and retest with confidence.
  • Get insight into the experience your responsive or mobile site delivers with mobile device emulation.
  • Schedule regular tests as frequently as every five minutes and compare key metrics over time.
  • Easily build tests into continuous integration solutions such as Jenkins and Team City.
  • Use scripted sessions to run tests that require complex interactions with your site, such as completing and submitting a form or adding a product to a basket.
  • Quickly pinpoint the performance bottlenecks on your site – easy-to-consume reports, including request maps, filmstrips and video, bring new insights to technical and non-technical teams alike.
  • Build your own dashboards or integrate results with other data sources with our powerful API

If you don’t have the time or resources to get the most out of Performance Analyser, we also offer it as a managed service.
