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 :)

exit1.dev▲11I'm trying to disrupt the insane pricing of uptime monitoring. I hope you'll help me out. I'm trying to create the absolute cheapest dev monitoring tool on the market, while still being competitive with all the others. This means $3/month plan, while still having monitoring for: Website, REST API, UDP/TCP, ICMP, Heartbeat/CRON, WS/WSS, DNS, Domain Intel/expiry and SSL. Everything with unlimited alerts through webhooks. I'm also taking an unlimited approach to the amount of checks you can have. I'd love to hear your thoughts.

It is a tool that helps web developers ensure that they have implemented helpful security mechanisms like HTTPOnly flags, X-Frame-Options, etc. There are hundreds of tools that offer to scan websites for things like cross-site scripting, mySQL injection, etc. This tool simply looks for information that is available via one or two GET requests (the headers, protocols,…
