Website Open Port Checker
Checks whether the target host responds on HTTP (port 80).
This tool sends a plain HTTP request to the target address on port 80 from our server and reports whether it got a response — a quick way to tell whether a web server is listening there, without installing anything.
It currently checks HTTP (port 80) only — not HTTPS (443) or a custom port. A blocked or missing response does not necessarily mean the host is down; it may simply not be listening on port 80, or a firewall may be filtering our server's traffic.
Frequently asked questions
What does this tool actually check?
It sends a plain HTTP GET request to the target address on port 80 and reports whether our server got a response within a short timeout — a basic open/listening check, not a full port scan.
Why isn't HTTPS (443) or a custom port supported?
Today the checker only tests plain HTTP on port 80. Support for HTTPS and a user-specified port is a possible future improvement, not yet built.
Why might it say "no response" even though my server is up?
A few common reasons: a firewall or security group is blocking our server's IP, the service only listens on HTTPS or a different port, the request timed out, or there's simply no HTTP service running on that address.
Is my IP address logged when I check it?
No — the address you check is used only to make the live request and is not stored. See About for the site's full privacy approach.
Does this work for private/internal IP addresses?
No — private-range addresses (like 192.168.x.x or 10.x.x.x) are recognized and skipped without a request, since our server has no route to your local network anyway.
