Announcing our May 2013 Release!

 Mark Isham on May 14, 2013. Category: announcements

At Zoompf we’re constantly looking for better ways to help you not only improve your website performance, but keep your website fast over time. We’ve been busy over the last few months, and wanted to take a moment to update you on the many new enhancements added to the Zoompf product recently.

As always, the best ideas come from our customers! If you have ideas to improve your Zoompf experience, please feel free to contact us. You may be surprised how fast our rock star development team can implement some of the best ideas!

Introducing Our Developer API

We’re proud to announce the public release of our Developer API! Have you wanted to customize the results of the Zoompf performance scan, or perhaps import the results directly into your own dashboard? Well now you’re in luck, our new RESTful API supports single page performance scans and returns all the great information you see in the UI. For more information, check out our API Developer Guide.

Performance Monitoring Email Alerts

Unless you never change your website, you’re always prone to introduce new performance regressions. To help you keep ahead of new performance problems, we’re happy to announce our new Email Alert system. When enabled, you will receive an email once a day with a prioritized list of all recent changes to your website that could cause a decrease in your site performance. This is a great tool to keep your site fast even as you introduce new content and functionality.

To enable, select the Monitoring tab, then Create Monitoring Job and add the appropriate email addresses to Email Alert Options.

“Share This Page” Link

Ever want to share a particular Zoompf performance result with a colleague without asking them to log in or wade through a 40 page report? Now you can do so via the “Share This Page” link at the top of each scan result issue page.

Simply click the link, copy-paste the URL from your browser, and embed in your bug tracker or send in an email. No logins required.

Re-Scan Webpage

Rerunning your webpage or website scan just got easier! If you are using complex scan options, you no longer have to re-configure those options with each new scan. Instead, look for the Re-scan button at the top of your prior scan and just click once to run again with the same options used for your last scan. This is ideal for periodically checkpointing a site, for example after a major code deployment.

Zoompf Scan Options


Re-scan works both for individual webpage scans as well as entire website scans. This option is only available on new scans initiated after May 12, 2013. Don’t see the option? Kick off a new scan and look in the new scan result under View Scans.

New Scan Options

We’ve listened to your feedback and added several powerful new scan options:

  • JavaScript Execution – When enabled, all passive Javascript content from the page will be fully executed and analyzed as part of the scanning process. This is especially useful if your page “lazy loads” content after document complete is triggered.
  • Third Party Content – Tried of skipping results for third party URLs for which you have no control over? Try disabling the “Third Party Content” option to examine only links off your site’s root domain.
  • Advanced Monitoring Options – When setting up a new monitor, you can now configure User Agent, HTTP Authentication, Deny Rules and Javascript execution, just as you can for an ad-hoc scan.

And More to Come…

We’re not sitting still at Zoompf! We’re already working on many great new features coming soon. 

If you have a particular request or are frustrated with how a current feature works, send us your feedback to support@zoompf.com and we’ll try our best to work your request into our backlog!
