Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server.

It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)
