I made tool that let's you see everything about any website
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. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. 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 :)

In plain words
Web Check is an open-source tool that gathers comprehensive information about websites, including metadata and security data in one place. It's designed for developers and security researchers who need to analyze website properties, IP addresses, and server details without paywalls or account requirements. The tool consolidates checks that typically require multiple separate applications, making it useful for those conducting website audits or security investigations.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
