Awesome tool that has continued to add features over time. It is a go to tool for my team to help troubleshoot and debug our publisher partner setups.

Very helpful debugging tool for any site monetizing with Google Ad Manager and prebid.

HTL Debug provides the most seamless way for me to review the contents of bid requests going to each of my SSP partners, and to see their responses. No more searching through the network tab, HTL Debug surfaces and organizes everything to do with prebid.js easily for AdTech users. Justin Wohl, CRO, Snopes.com

HTL Debug is a wonderful tool that I use often. It gives me insights into how other sites are using ad tech, saving me a great deal of time and effort. It also provides an easy way to link to line items, orders and many order attributes directly back to GAM. I consider this an essential tool in my Ad Ops tool belt. James Kober / Newsday LLC

This is the best Prebid and Google Ad Manager debugging extension I've ever used.

I'm biased since I work for the company that produced it, but I use the extension daily and I've heard many people talk about loving it! It's the most comprehensive ad debugger/inspector for publisher ad tech imho.
