Free Link Back Tool - to check verified and submitted, existing links

I started pushing tier 1 backlinks with SEO Autopilot.
GSA SER proved useless, I must be doing something wrong there.
I plan to blast those tier 1 links with XRumer and see how it goes.
But I need to be sure the tier 1 contains links to my money site.
So I want a free tool for that.
I could code it myself but this is my side hussle and I don't want to spend time on it.

Something like this
