Motivation

Often when I'm looking into a website, there's several things I always check first. None of this is hard, and can usually be done with a series of curl commands, or using a combination of online tools. But it's so much easier to have everything presented clearly and visible in one place.

Features

• Server Location
• SSL Info
• Headers
• Associated hostnames
• Domain Whois
• DNS records
• Cookies
• Server info
• Crawl rules
• Performance metrics
• Screenshot
• Tech stack
• Site response times

Note that not all checks will work for all sites. Sometimes it's not possible to determine some information, and there are limitations imposed by Netlify for the lambda functions.

Architecture

It's just a very simple web app (React + TypeScript), with results calculated using a series of Lambda functions. Everything is deployed on Netlify. Most things are done with the native http interface, but there's a few instances where this wasn't possible alone, so is combined with some external APIs, like Shodan for hostnames, IP Info for geolocation, and Google Cloud for performance metrics.
