What You Get
One Lookup, Full Picture
Every check returns hosting provider, server location, DNS, SSL, and performance data — all from a single query.
Hosting Provider Detection
Find out if a site runs on AWS, Vercel, Cloudflare, or any of 2,000+ providers — cross-referenced from WHOIS, IP, and ASN data.
Server Geolocation
Pin down the data center, city, and autonomous system behind any IP. Useful for latency analysis and compliance checks.
SSL & Security Headers
Inspect the full certificate chain, expiry dates, and security headers like HSTS, CSP, and X-Frame-Options at a glance.
Response Time Metrics
Measure TTFB and total response time so you can benchmark competitors or verify your own deployment performance.
Full DNS Breakdown
Pull A, AAAA, MX, TXT, CNAME, and NS records in one lookup — no need to juggle separate dig commands.
Developer-First API
Integrate hosting lookups into your own tools with a RESTful API. JSON responses, API key auth, and clear rate limit headers.
Change Tracking
See when a domain switched hosts, changed DNS, or moved CDNs. Invaluable for due diligence and migration audits.
CDN & Edge Detection
Detect Cloudflare, Fastly, Akamai, and other CDNs automatically — including edge locations and caching behavior.

Wall of Love
Used by Security Teams, DevOps, and Developers
From pentest recon to competitive monitoring — here's how teams use HostingChecker.
"We run it against every client domain before a pentest kickoff. Knowing the hosting stack upfront saves a full day of recon."
"Piped the API into our monitoring dashboard — now we get Slack alerts whenever a competitor changes hosting or CDN. Took 20 minutes to set up."
"Client sends me a domain, I paste it in, and I know within seconds if they're on shared hosting, a VPS, or behind Cloudflare. Beats digging through whois manually."
"We used the historical data to verify that an acquisition target had actually migrated off a legacy host. Would have missed it otherwise."
"I track 40+ competitor domains with the API. When one of them switches from AWS to Vercel, I know about it the same day."
"Started on the free plan to test it for a side project. Upgraded to Pro within a week once I realized how much time it saved on DNS debugging."
