Technology detection, SEO analysis, SSL checking, DNS lookup, HTTP headers, website speed, IP finder, WHOIS, redirect tracing, and status monitoring — all free, all in one dashboard. No switching between different services.
No sign-up, no email, no credit card. Every tool works instantly. We believe web analysis data should be accessible to everyone — from a student learning web development to a senior engineer auditing production.

Enter any URL and our tools will perform a live scan — analyzing HTTP headers, HTML source code, DNS records, SSL certificates, WHOIS data, and more. Every result is pulled in real-time, so you always see the current state of the website, not stale cached data.
