I received no request to review and no reward for endorsing …this is an honest opinion of my own.
You may ask…why would I want an alternative to GTMetrix.com? They are referenced everywhere including in this site for their benchmarks. Well….a funny thing happened over the year … a competitor that was less popular bought GTMetrix or did something … and is now the engine of GTMetrix. Its the same thing as Lighthouse … sadly no one thought to ask why if Lighthouse was so great … why weren’t they number one?
So the GTMetrix tests I referenced in previous articles are no longer the tests that you can get from GTMetrix. Lighthouse isn’t horrible … but it kinda is. It gives an extremely limited glimpse at only a select group of submetrics.
https://www.webpagetest.org/ – A great alternative that gives a user a rich wealth of data is webpagetest.org As an example you can see just how much and how portable the data is with their csv raw data download.210520_AiDcDE_8c8dff88f5b9d6f9b8e9a78592443c31_summary
Another site that focuses heavily on images and their cost to the load time experience is https://webspeedtest.cloudinary.com/
