Description

Lighthouse is an open-source, automated tool for improving the performance, quality, and correctness of your web apps. When auditing a page, Lighthouse runs a barrage of tests against the page, and then generates a report on how well the page did. From here you can use the failing tests as indicators on what you can do to improve your app. * Quick-start guide on using Lighthouse: https://developers.google.com/web/tools/lighthouse/ * View and share reports online: https://googlechrome.github.io/lighthouse/viewer/ * Github source and details: https://github.com/GoogleChrome/lighthouse

The PSI report and Lighthouse reports return conflicting results, and they can't even tell if the contrast ratio is ok -- I had it return fail on a site with good contrast ratio, and pass on a site with very bad contrast ratios.

"Why can't I easily find the mobile-friendly view option? It's frustrating and a waste of time."

Doesnt work for Chrome in Mac. The browser is updated to the latest version. It doesn't even give any error or compatibility issues with other plugins that I am using.

Latest version broke. :( Good thing there's an alternate way in Chrome to run the report.

It works, but the problem is that it hasn't been updated in so long that it is using an old Lighthouse version. Even get a lil notification saying that. So it's better to just use an alternative means of getting this data.

Used to work offline as version 5.4.0.0 but now with version 100.0.0.0 it fails while it looks for gitHub.

I think this tool has great potential, but unfortunately, at the moment it is only possible to run an audit emulating on mobile Nexus 5X and using a 3G network connection, which doesn't make much sense to me. At its current state, I'll stick to the DevTools version, where it's possible to choose the emulation options.

Why is this emulating a nexus... on a 3G network? Does anyone even use 3G anymore? Lets get a bit more modern and use LTE or WIFI speeds and stop throttling, or at least allow user running the test to set their own environment.

It always try to run mobile checks first, so sites redirect to mobile version and this bornbroken thing start to test only mobile site.

Why PWA check is gone?

New update that removes it from the developer tools limits the functionality to only giving it an URL. This limits websites that use auth in different ways such as cookie tokens, tab exclusive auth tokens, etc. It opens on a new tab which I rather not.

Works well but gives totaly different report than the console version of lighthouse. Why? whats up with that?

Sadly, this hasn't been updated since Version 8.0 and the latest is 8.3. If you rely on this tool now, you're getting a way different reading from what Google is getting.

It doesn't support incognito mode. If I run a test in incognito mode, it opens the test result in normal browser, fix this issue plz then it will be worth of 5*

This extension is now built in to Chrome dev tools.

The overview forgets to mention, you don't need this extension anymore - the feature it built into DevTools in the current version of Chrome. Installing this gives you nothing new. Just use the "Audits" tab in DevTools.

It's a good tool, but as it stands it can only generate one report, then the extension needs to be deactivated and reactivated because all buttons in its GUI stops responding after the first usage.
