PageSpeed Insights (MV3)
Analyze the performance of your webpages and get specific suggestions on how to optimize them.
1. This extension is experimental.
2. The UI is using the open source code, which is different from the current (deprecated) PageSpeed Insights extension.
3. If you are using ARM-based computer, this is your only choice for PageSpeed Insights for now.
[ NOTE: if you find any bugs, please file an issue at https://github.com/songlibo/pagespeed-chrome-extension/issues ]
Update:
2023-01-26 v0.0.2.0 Rewrite the some C++ code for WebAssembly, and migrated the extension to manifest_version:3.
2022-07-14 v0.0.1.11 Removed pnacl module as it is deprecated. Stay tuned for a new implementation of the running code.
2018-07-10 v0.0.1.10 Fix issue/34. Background color.
2018-02-04 v0.0.1.9 Fix issue/30. Chrome 65 changes an object type from Date to string.
2017-08-22 v0.0.1.8 Fix issue/29, which mark data uri for caching. Also show a button in the browser action popup to open PageSpeed Insights online.
2017-04-26 v0.0.1.7 Fix issue/6, which breaks when the extension is updated. Also add a link to the options page.
2017-04-25 v0.0.1.6 Fix localStorage issue/26, and ignore extension files issue/8. Default to use lossy compression for images (option to revert back to lossless), add option to compressing images using Guetzli (warning: use a lot of memory, and very slow).
2017-03-02 v0.0.1.5 Fix issues/22, 24. Fix language selection in options, show RTL for Arabic and Hebrew, and save/load result.
2016-11-30 v0.0.1.4 Fix issues/21. FileError is not defined.
2016-11-09 v0.0.1.3 Fix issues/20. Optimized Images don't work.
2016-02-19 Detect NaCl plugin before running PageSpeed. If NaCl is not available, the PageSpeed will not start, and give a better message to install or enable the plugin.
2015-12-25 Update the issue link on github so that you can file bugs and request features.
2015-10-01 Add the missing guide (popup when clicking the icon).
2014-02-21 Add loading progress -- the loading of PNaCl is very slow when first installed or updated. It should be fast afterward.

There is a better replacement if you just need to be redirected to pagespeed.web.dev. Please search "PageSpeed Insights Shortcut" : https://chromewebstore.google.com/detail/pagespeed-insights-shortc/pnibhbifpoiplpgkaajjejeigfchahpl

Great tools, however, the latest version freezes when fetching the HAR about half the time. Seems to require a reboot of Windows to make it work again. Killing Chrome completely doesn't solve the problem.

Great extensions. Thx for efforts you put in it. I have a few recommendation to make it much better. How I could talk to you personal?

Все работает. Если вы будете запускать html файлы с диска то он не запустит. НУжно запускать только с виртуального сервера!
值得一试

Все работает, только неудобно лезть в консоль разработчика - но это не проблема.
F12 нажали - в табах выбрали "Page Speed". Нажали - "START ANALYZING". ВСЕ РАБОТАЕТ !!! =)

Doesn't work. Renders "Page not Fount"
Getting the same behavior described by Manan Patel The installed icon is decorated with the word "beta" white on green background. Are you kidding me? Does Google really publish "BETA" extensions? Anyway when the icon is clicked the message is: This webpage is not found ERR_FILE_NOT_FOUND With a link labeled "DETAILS". When DETAILS link is clicked the following message comes up: No webpage was found for the web address: chrome-extension://lanlbpjbalfkflkhegagflkgcfklnbnh/guide.html
