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.

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.
