Great to have all of these tools in one place. I use at least half of these tools on a regular basis, but each from different websites. I used the SEO auditor on my website and got some good insight with warnings on the length of the Title tag. One idea, for the Network section, I used to work with TCP captures and they are sometimes really challenging to read (tracking a message with it's acknowledgement, a 3-way handshake connection protocol, etc.). A tool that analyzes and shows a readable copy of a TCP capture would be great, something similar to Wireshark but easier to read and understand. Great work!

I love the "books for dads who like Pavement" prompt! It would be great if you could incorporate the same experience of "browsing" random page of some of the results that are returned
