CrXPRT 2 functionality is ending with ChromeOS 139

Back in January, we discussed the ChromeOS team’s decision to eventually end support for all user-installed Chrome Apps—including CrXPRT 2—upon the release of Chrome 138 in July of this year. As best we can tell, the move is part of their overall strategy of transitioning all support to Chrome extensions and Progressive Web Apps. We knew that after the support cutoff date, we would not be able to publish any fixes or updates for CrXPRT 2, but we weren’t exactly sure how the transition would affect the app’s overall functionality.

We’ve now confirmed that while CrXPRT 2 still functions normally through Chrome 138.0.7204.255 (beta), the app does not launch at all on Chrome Canary 139. Consequently, we expect that stable channel system updates will disable CrXPRT 2 on most systems after Chrome 139 goes live on August 5th. We will initially leave CrXPRT 2 on our site for those who want to use it on older versions of Chrome, but over time we will archive it as an inactive benchmark.

We want to extend our heartfelt thanks to the many people around the world who used CrXPRT 2 for lab evaluations, product reviews, and individual testing over the past several years. We’re grateful for your support! We will update readers here in the blog if we decide to pursue new ChromeOS benchmark development work in the future.

An update on CrXPRT support in ChromeOS

Justin Greene
By Justin Greene
on January 16, 2025

CrXPRT users may remember that back in 2022, we discussed the ChromeOS team’s decision to end formal support for Chrome Apps and instead focus on Chrome extensions and Progressive Web Apps. This decision meant that we would not be able to publish any future fixes or updates for CrXPRT 2, although moving forward, we weren’t sure how it would affect the app’s functionality.

After receiving a lot of feedback regarding their original timeline, the ChromeOS team decided to extend Chrome App support for Enterprise and Education account customers through January 2025. Because we publish CrXPRT through a private BenchmarkXPRT developer account, we assumed at the time that the support extension would not apply to CrXPRT.

Recently, the ChromeOS team released new information about their scheduled support timeline. Now, they plan to end formal support for all user-installed Chrome Apps in July 2025 (Chrome 138). In February 2028, the Chrome 168 release will mark the end of life for all Chrome Apps.

The good news is that—in spite of a lack of formal ChromeOS support over the past couple of years—the CrXPRT 2 performance and battery life tests have continued to run without any known issues. As of today, the app functions normally up through the Beta release of ChromeOS version 132.0.6834.52.

We will continue to run the benchmark on a regular basis to monitor functionality, and we will disclose any future issues here in the blog and on CrXPRT.com. We hope the app will continue to run both performance and battery life tests well into the future. However, given the frequency of Chrome updates, it’s difficult for us to predict how long the benchmark will remain viable.

If you have any questions about CrXPRT, please let us know!

A note about CrXPRT 2

Justin Greene
By Justin Greene
on August 31, 2023

Recent visitors to CrXPRT.com may have seen a notice that encourages visitors to use WebXPRT 4 instead of CrXPRT 2 for performance testing on high-end Chromebooks. The notice reads as follows:

NOTE: Chromebook technology has progressed rapidly since we released CrXPRT 2, and we’ve received reports that some CrXPRT 2 workloads may not stress top-bin Chromebook processors enough to give the necessary accuracy for users to compare their performance. So, for the latest test to compare the performance of high-end Chromebooks, we recommend using WebXPRT 4.

We made this recommendation because of the evident limitations of the CrXPRT 2 performance workloads when testing newer high-end hardware. CrXPRT 2 itself is not that old (2020), but when we created the CrXPRT 2 performance workloads, we started with a core framework of CrXPRT 2015 performance workloads. In a similar way, we built the CrXPRT 2015 workloads on a foundation of WebXPRT 2015 workloads. At the time, the harness and workload structures we used to ensure WebXPRT 2015’s cross-browser capabilities provided an excellent foundation that we could adapt for our new ChromeOS benchmark. Consequently, CrXPRT 2 is a close developmental descendant of WebXPRT 2015. Some of the legacy WebXPRT 2015/CrXPRT 2 workloads do not stress current high-end processors—a limitation that prevents effective performance testing differentiation—nor do they engage the latest web technologies.

In the past, the Chromebook market skewed heavily toward low-cost devices with down-bin, inexpensive processors, making this limitation less of an issue. Now, however, more Chromebooks offer top-bin processors on par with traditional laptops and workstations. Because of the limitations of the CrXPRT 2 workloads, we now recommend WebXPRT 4 for both cross-browser and ChromeOS performance testing on the latest high-end Chromebooks. WebXPRT 4 includes updated test content, newer JavaScript tools and libraries, modern WebAssembly workloads, and additional Web Workers tasks that cover a wide range of performance requirements.

While CrXPRT 2 continues to function as a capable performance and battery life comparison test for many ChromeOS devices, WebXPRT 4 is a more appropriate tool to use with new high-end devices. If you haven’t yet used WebXPRT 4 for Chromebook comparison testing, we encourage you to give it a try!

If you have any questions or concerns about CrXPRT 2 or WebXPRT 4, please don’t hesitate to ask!

An update on Chrome OS support for CrXPRT

Justin Greene
By Justin Greene
on July 14, 2022

In March, we discussed the Chrome OS team’s plan to end support for Chrome apps in June and instead focus their efforts on Chrome extensions and Progressive Web Apps. After receiving feedback on their published timeline, the Chrome OS team decided to extend Chrome app support for Enterprise and Education account customers through January 2025. Because we publish our Chrome app (CrXPRT) through a private BenchmarkXPRT developer account, and because we have not seen any further updates to the support timeline, we don’t assume that the support extension will apply to CrXPRT.

Since June has come and gone, and the support extension probably does not apply to our account, we do not expect to be able to publish any future fixes or updates for CrXPRT. As of now, and up through Chrome 105, the CrXPRT 2 performance and battery life tests are still working without a hitch. We will continue to run the benchmark on a regular basis to monitor functionality, and we will disclose any future issues here in the blog and on CrXPRT.com. We hope the app will continue to run both performance and battery life tests well into the future. However, given the frequency of Chrome updates, it’s difficult for us to predict how long the benchmark will remain viable.

As we mentioned back in March, we hope to begin development of an all-new Chrome OS XPRT benchmark by the end of this year. We’ll discuss that prospect in more detail in future blog posts, but if you have ideas about the types of features or workloads you’d like to see in a new Chrome OS benchmark, please let us know!

CrXPRT 2 on FydeOS!

Justin Greene
By Justin Greene
on April 28, 2022

Recently, a tester contacted us with details from a CrXPRT 2 performance test run that they’d successfully completed on… an Apple MacBook Pro! Because CrXPRT 2 is a Chrome Web App that we designed for Chrome OS, it was quite a surprise to hear that it is now possible to run CrXPRT 2 on non-Chrome OS platforms by using FydeOS.

FydeOS is an operating system based on a fork of the Chromium OS project. Developers originally intended FydeOS to be a Google-independent, Chrome-like alternative for the Chinese educational market, but FydeOS is now available to the English-speaking consumer and enterprise markets as well. FydeOS users can run a Chrome-like OS on something other than a Chromebook or a Chromebox, such as a PC, Mac, virtual machine, or even a Raspberry Pi device. Additionally, FydeOS supports Android, Chrome OS, and Linux apps, and users can run those apps at the same time on the same screen.

We have not yet conducted any testing with FydeOS in our lab, but we wanted to pass along this information to any readers who may be interested. If the OS operates as described, it may provide a way for us to experiment with using CrXPRT 2 in some interesting cross-platform tests.

Chrome OS support for CrXPRT apps ends in June 2022

Justin Greene
By Justin Greene
on March 24, 2022

Last March, we discussed the Chrome OS team’s original announcement that they would be phasing out support for Chrome Apps altogether in June 2021, and would shift their focus to Chrome extensions and Progressive Web Apps. The Chrome OS team eventually extended support for existing Chrome Apps through June 2022, but as of this week, we see no indication that they will further extend support for Chrome Apps published with general developer accounts. If the end-of-life schedule for Chrome Apps does not change in the next few months, both CrXPRT 2 and CrXPRT 2015 will stop working on new versions of Chrome OS at some point in June.

To maintain CrXPRT functionality past June, we would need to rebuild the app completely—either as a Progressive Web App or in some other form. For this reason, we want to reassess our approach to Chrome OS testing, and investigate which features and technologies to include in a new Chrome OS benchmark. Our current goal is to gather feedback and conduct exploratory research over the next few months, and begin developing an all-new Chrome OS benchmark for publication by the end of the year.

While we will discuss ideas for this new Chrome OS benchmark in future blog posts, we welcome ideas from CrXPRT users now. What features or workloads would you like the new benchmark to retain? Would you like us to remove any components from the existing benchmark? Does the battery life test in its current form suit your needs? If you have any thoughts about these questions or any other aspects of Chrome OS benchmarking, please let us know!
