I’m looking for online tools that I could use to make sure my website is responsive and working properly on diffrent platforms and browsers. Also, I would like any other relevant tools like loading speed testing and so on.
Hi @Laurence_De_Larochel, if you are looking for a good free tool that gives really good advise to find the real bottlenecks, then Pingdom is a great tool for this: https://tools.pingdom.com/
They have a very spot on analysis that can help you to find the biggest bottlenecks:
Page weight
Number of page requests
Amount of script used
Those are the biggest factors that affect site performance after the core Webflow files load, which are really small.
A good rule of thumb, I try to keep page weight between 1-2mb, requests on page between 50 and 70 and script running on page to be no more than 15% of total payload.
