So, I'm curious. How does https://calibreapp.com/ compare to https://www.webpagetest.org/ and https://www.sitespeed.io/ and https://gtmetrix.com/ ? Why would someone want to pay you for your service, as opposed to using any of the above? Do you support browsers other than Chrome? Do you support a wide variety of simulated hardware? Do you support a wide variety of testing locations? Do you support any page speed test profile other than Lighthouse and Google Page Speed? Do you support running your software in a Docker container of my own choice? Because I can get all those things via one or more of the competitors in this space, and I'm not seeing any compelling reason to even look at Calibre. Please feel free to convince me that I'm wrong. |

One of the key deciding factors is do you want to run the service yourself e.g. VMs, containers, in multiple regions or do you want to make that someone else's problem and get on with running your business - most of my clients are in the later camp
Both Calibre and SpeedCurve have clean UI's that allow performance to be tracked over time, from multiple locations and integration with other services via web hooks, APIs etc.
GTMetrix is old and outdated IMV, - it still heavily relies on YSlow rules which are well past their sell-by-date
WebPageTest is my favourite (SpeedCurve uses it under the hood) but it's got no ability to track over time, SiteSpee.io is really nice too but is self-hosted.
With the exception of some real devices in Dulles, all of the products rely on emulation for mobile, and Safari is a real gap for them all too
