  • A PageSpeed insight report, but for every page in your domain
    Trust neither. The most optimal option I've found is webpagetest.org Its been quite handy lately. This tool does look interesting. Source: about 3 years ago
  • How are you all accurately checking your website load time? Not sure PageSpeedInsights is very helpful.
    Webpagetest.org is another. Pagespeedinsights and lighthouse are great for identifying page load issues to fix, but actual page load times will always vary between the user and your web server. Universal analytics has some page load timings but that's going away soon and nothing afaik is in GA4. I've seen an example of building a page load timer in tag manager and dumping the results into an event. Source: over 3 years ago
  • Extreme confusing over Speed Index results -- webpagetest.org

I am running tests using webpagetest.org, and I am having trouble fully understanding the speed index results as well as the film strip view. The page renders quite fast everywhere I test it. Google Lighthouse shows it in the 90s + for performance score, however when I test the page on webpagetest, I get load times of 77 seconds (NOT MS) which is... Source: over 3 years ago
  • Does anyone else experience pure ecstasy when they get 100 on Lighthouse? ๐Ÿ˜ฉ
    Webpagetest.org is great, and checking OP's site they have done an incredible job, I don't think I have ever made or seen an Ecom site this slick. Super clean waterfall view. Source: over 3 years ago
  • Performance scores for Google Lighthouse/Insights seem to be very inaccurate
    Thanks for the recommendation regarding webpagetest.org, another user made a similar recommendation so I will check it out. Source: over 3 years ago

  • Introducing fulgur: a blazing fast HTML-to-PDF engine in Rust โ€” no browser required
    I run Devin Review and CodeRabbit on every PR. PDF spec edge cases and CSS layout corner cases are exactly the kind of thing where having a second pair of eyes matters, and as a solo maintainer I don't have human reviewers. Both tools have caught real issues, especially around pagination edge cases. - Source: dev.to / 3 months ago
