Announcing the New Face of Zoompf! (Now Live)

Last May we announced the beta release of the new face of Zoompf and the response has been fantastic! Beyond the substantial overhaul to the interface usability, we also released a trove of new features including reusable performance tests, new data rollups (compression savings, image savings, caching savings, etc.), new third party content analysis tools, content/waterfall charts and much, much more!

In the 4 months since that announcement, we’ve been hard at work on additional features including new performance comparison tools, recurring performance tests, new testing options for password protected pages, ignore defects support, and HAR integration with tools such as WebPageTest. You can see the full rundown of all the announcements here.

So what are we announcing today?

Well after months of bug fixes, enhancements and great feedback, the time has come to take the training wheels off and remove the “beta” label. On Friday, October 16th we will be retiring the old interface of Zoompf (referred to lovingly as “Zoompf Classic”) and henceforth only supporting the new Zoompf interface moving forward.

To prepare for this, here’s what you need to know:


Will I lose my old performance scans?

Nope! All performance scans you’ve already run have already been migrated into the new interface. Any new scans you perform in the old interface between now and October 16th will be migrated on October 16th before the old interface gets turned off.

What about my monitors?

The Zoompf Monitors available in Zoompf Classic have been replaced with Recurring Performance Tests, described here. If you want to take advantage of recurring performance tests, you will need to set those up yourself in the new interface.

What am I giving up?

All the great data and tools you used in Zoompf Classic are still there, just organized in a manner to streamline your workflow and help you find performance defects more quickly. You can still drill down to the same level of detail, and many new tools have also been added.

Can I use the new version now?

Absolutely! Bookmark https://my.zoompf.com and log in today. Any tests you run in the new interface right now will remain after October 16th without change.

What is a “Performance Test”?

This is perhaps the biggest conceptual change from Zoompf Classic. A Performance Test is a reusable test configuration that you can run again and again, useful for comparing results over time. For example, one performance test may analyze your homepage for iPhone 6 performance defects, while another test may analyze your checkout page as a desktop chrome user. Performance tests can be easily re-run without the need to reconfigure the testing configuration. This allows you to easily compare “apples to apples” results over time.

What is a “Performance Snapshot?”

Every time you run a Performance Test, a Performance Snapshot will be created. A snapshot is a point in time capture of a specific testing configuration. While snapshots are the most similar to “performance scans” in Zoompf Classic, they now share a common Performance Test to make comparisons and re-running tests a snap.

Will the API break?

The root URL of all API calls will be changing as follows:

Old root:

New root:

For example,


No other changes should be necessary. If you already use the API, we should have already contacted you regarding the change. If you have not been contacted, please contact us and we’d be happy to work with you on the migration to the new structure.

What else is new?

So much! We’ve been very busy this year with the updates. I recommend first catching up on all our announcements, then contact us for a demo. We’d be happy to walk you through the changes and answer any questions you may have.

 So bottom line it for me, what do I need to do?

  • If you used Zoompf Monitoring, you’ll want to consider setting up new recurring tests.
  • If you used the API, you will need to change your API URL.
  • Other than that, nothing. Just log into the new UI at https://my.zoompf.com and start some new tests!

We hope the new version of Zoompf is helpful to your performance optimization efforts! Of course, we won’t be standing still – we have a lot of great updates planned for the near future! And as always, we’re here to help. Contact Us with any questions!
