FREE TOOLS
Free tools to check a domain or website.
Check an SSL certificate, DNS records, WHOIS details, an IP address or whether a site is up, and make a strong password. Every tool is free and needs no sign-up.
SSL checker
See who issued a site's certificate, when it expires, the names it covers and whether browsers trust it.
DNS checker
Ask Cloudflare, Google and Quad9 for a record at the same time and see whether they agree.
WHOIS lookup
Find a domain's registrar, creation and expiry dates, status and name servers. Works for .pk domains too.
IP lookup
See your own IP address, or find which network and country an IP address belongs to.
Website up or down checker
Load a page once and see the status code, how long it took, the time to first byte and every redirect.
Password generator
Make a random password in your browser. It is never sent anywhere, not even to us.
How do these tools work?
The SSL, DNS, WHOIS, IP and uptime checks run on our server, so they show what the public internet sees, not what your own computer has cached. We do not save the names or addresses you check.
The password generator runs only in your browser. The password it makes never leaves your device.
To keep the tools quick for everyone, each tool allows 20 checks every 10 minutes from one connection.
