IsLegitSite checks whether a website may be a scam and reports its reputation through the Site Trustworthiness API.
Web Check
Web Check analyzes a website’s infrastructure and security signals through an OSINT and site diagnostics tool.
About Web Check
Web Check is a browser-based tool that runs infrastructure and security checks against a website's domain and page, then presents the results as a single overview. Reported items include DNS records, WHOIS and domain details, TLS configuration and certificate chain, HTTP response headers, cookies, open ports, server location, tech stack, trackers and third parties, crawl rules, Lighthouse quality metrics and an estimated page carbon footprint. Some checks are drawn from third-party sources such as Shodan, SSL Labs, the Wayback Machine, Have I Been Pwned and Tranco, so those results reflect what those services record. The homepage states 44 supported checks and shows results in about 20 seconds. Pricing is not stated.
