22 Tools, One Hub

Every network check, one click away.

Whois, DNS, SSL, headers, redirects, uptime and speed — pick a tool below and get an instant answer, straight from your own server.

No tools match that search.

Whois Lookup

Raw registry whois record for a domain.

Queries the domain's registry whois server directly on port 43.

Domain Age Checker

How old is this domain, based on its registration date.

Parses the Creation Date field from the whois record.

Domain to IP Lookup

Resolve a domain to its IP address(es).

Uses the server's DNS resolver (A records).

DNS Record Lookup

A, AAAA, MX, NS, TXT, CNAME or SOA — pick a type.

PHP dns_get_record() against the server's resolver.

SPF Record Checker

Check if a domain has a valid SPF TXT record.

Looks for a TXT record starting with v=spf1

DMARC Record Checker

Check if a domain has a valid DMARC policy.

Looks up TXT record at _dmarc.<domain>

DNS Propagation Checker

Compare the A record across Google, Cloudflare and Quad9 resolvers.

Queries public DNS-over-HTTPS endpoints, not just the local resolver.

SSL Certificate Checker

Issuer, validity window and days left on a host's SSL certificate.

Connects on port 443 and parses the certificate directly.

HTTP Header Checker

See the full response headers for any URL.

Follows redirects, then reads the final response's headers.

Security Headers Checker

Checks for HSTS, CSP, X-Frame-Options and other protective headers.

Score out of 6 recommended security headers present.

URL Redirect Checker

Trace the full redirect chain for a URL, hop by hop.

Follows each 3xx Location header up to 10 hops.

URL Expander

Paste a shortened link (bit.ly, t.co, etc.) to see where it actually goes.

Follows every redirect hop until it reaches the final destination.

Canonical URL Checker

Reads the page's <link rel="canonical"> tag and compares it to the URL you entered.

SEO tip: canonical should usually match the URL itself unless it's intentionally pointing elsewhere.

Broken URL Checker

Crawls a page's links (up to 20) and checks each one's status, in parallel.

Checks only the first 20 unique links found on the page, for speed on shared hosting.

URL Shortener

Generate a short link that redirects to your original URL.

Stored in a local SQLite file next to this tool — no external database needed.

URL Encoder / Decoder

Percent-encode or decode any string, entirely in your browser.

URL Parser

Break a URL into protocol, host, path, query and fragment.

My IP Address

The IP address this server sees you connecting from.

If you're behind Cloudflare/a proxy, the forwarded-for address is shown too.

IP Lookup

Approximate location and ISP for any public IP address.

Uses the free ip-api.com geolocation service.

Website Uptime Checker

Is this site up right now, and how fast did it respond?

Website Speed Test

Real timing breakdown: DNS, connect, SSL, TTFB and total load.

Measured server-to-server from this hosting account, not from a browser.

User Agent Parser

Detect browser, OS and device type from a user-agent string.
