Über IfPort
a free tool to check your public connection from the outside
IfPort shows which TCP ports are reachable on the public IP making your request. Run a check from your browser, a terminal, or an AI agent through our hosted MCP server.
If a check helped, a couple of dollars can help cover the server bill and keep IfPort online. Checks stay free, with the same limits for everyone.
Try it at ifport.io. Thanks for helping keep it running!
