I'm launching this as somewhat of a beta as it was a testing ground for new tools I've been creating as a template for another project. It allows you to "somewhat" monitor sites and hosts inside the Tor Network. I plan to release the endpoint source code and the app source code in the coming months to allow for self-hosting.
Related, this monitors all the major Tor hidden services, including any new site anyone submits: https://rnsaffn.com/zg4/
