Customers are the lifeblood of your business. This is why we believe that monitoring the experience of the end user should be the top priority. To properly monitor and forecast a site’s performance and your user’s experience, you need to ensure you measure your site the way your users actually experience the site.

Accurately assessing your user’s performance is important; this is why we rolled out Network Throttling late last year. We are excited to continue that trend today and announce that Rigor supports real Chrome browsers for both Monitoring and Optimization, in addition to our existing support of Firefox.

Why Chrome

Just like you should control for network connections when measuring mobile UX, it is also important to ensure you align how you are measuring performance with your users’ browsers. Chrome is the most used browser for both desktop and mobile with 44.5% of the market share. It is also the default browser on Android devices, which are the most widely used mobile devices. As such, the majority of mobile traffic is also via Chrome.

Given the prevalence of Chrome, this is the browser of choice for testing. In some instances, it also might be the only browser tested.

Not only is Chrome leading the way in terms of market share and testing, it is also at the forefront of adopting new web technologies. By supporting Chrome, Rigor is supporting all the new technologies that customers will need.

Access to More Metrics

We love data because we know that the right data helps drive decisions and improvements. You know best which key performance metrics, baselines, and timings are most important to your business. Chrome provides more user metrics than Firefox, particularly around performance. Via built in profiling tools, Chrome can respond to specific requests such as “tell me what kind of JavaScript is slow.”  

Additionally, Chrome is leading the way in adding useful metrics such as when various painting or rendering events occur, so this provides even more capabilities going forward.

Continuous Improvement

By automatically checking for and downloading new versions of itself, Chrome ensures that users are current with features, measurements, and capabilities. Users don’t have to worry about what version they are running so you can ensure you’re measuring their experience accurately.

This also means that, since the vast majority of people quickly adopt the latest version with the latest technology, websites quickly adopt to using the latest technology capabilities of Chrome. No one is using an 8 month old version of Chrome, so you shouldn’t test under those conditions, either. As new versions of Chrome come out, we will automatically update our monitoring network to use the newest version.


To get an accurate picture of your user’s experience it is important to test under the same conditions that they are using. By adopting support for real Chrome Browsers, Rigor  is helping our customers gain better visibility into the user’s experience and stay current with the latest in browser technologies.
