tool screening website (white label) for my sellers

hi… I'm looking for a software with the Label that does an automatic screening of any website (example: find broken links, social links, site speed, etc. etc.) my marketing agency needs. I would like to give it to my sellers so when they are in a negotiation with the customer they can do an automatic and fast screening of the customer's website in real time. I know that there are tools that do all this, they are also in white label, I can use it with my brand as if it were mine. can you help me find it… do you know this kind of tool? thank you
