Port Checker
Check whether your TCP/UDP ports are open from the internet — ideal for validating firewall rules and port forwarding.
This tool will be available very soon: it needs a service that tests ports over TCP, and we are setting it up.
Admin: enable it by deploying backend/port-check/ and setting
site.portCheckApi in config.js.
The port check uses our own backend · the rest of the site runs locally.
