The recent shutdown of SSLPing and related comments made me think. There are so many generous individuals or organisations who host open source services for free on their infrastructure. I'm thinking of federated networks like Matrix or Mastodon or utilities like Jitsi, Cyberchef or SSLPing. Useful things if you know where to find them. I know of a few gists and pastebins floating around but this is a poor solution in my opinion. Wouldn't it make sense to have a centralized or federated database with such tools combined with servers where they are hosted? Does this already exist somewhere?
