Your photos, your files, a website or a game server, kept at home instead of on someone else's computer. Whether that can work depends on your connection, and “me-web?” tells you, in plain words.

It checks your connection and your device one step at a time, from this phone to your router, your provider and the internet, and then says what you could host at home, what stands in the way, and what would fix it:

• a website, reaching home from outside, family photos and files, a game or voice server, a fediverse or blog server, a mail server: possible, possible with a workaround (and which one), or can't tell;
• whether your provider shares your public address with other customers (CGNAT), or a second router is in the way;
• whether your router opens ports for the apps that ask it to (UPnP, NAT-PMP, PCP);
• on mobile data, the operator and the type of network (5G, 4G);
• only if you agree: whether the outside world can really reach this device, with ports opened for ten minutes and closed afterwards;
• whether this connection could send mail directly;
• how your public address has changed across your earlier checks.

What it knows about providers is inside the app, not fetched from a server. Your findings stay on your phone unless you choose to share them, after reading exactly what is sent, and you can delete them at any time.
