Here is a free online tool to check Cloudflare for your website to see if the content is being served to the visitors from the cache. Also, if some resources are not loading properly from the Cloudflare cache then this tool here will let you know. All you have to do is input your site URL and then it will run a quick check to show you results.
Many websites that use Cloudflare network use the cache tool as well. This is to make sure that visitors always get an online site in case the main server goes down. However, sometimes a few resources on site do not load correctly from the cache. Since there is no direct tool to audit that; you can reply on the online tool I have mentioned here.
The Cloudflare cache checker here basically analyses the “Cloudflare’s Cache Headers” and show you their details for your site. There are various parameters for those headers and if a resource is not able to load properly then you will know by looking at the status of its header.
