- The first screen is three cards you scroll through: what you could have (your family's photos at home, open from anywhere), how it works (a small computer that stays on, and an address of your own), and the question that matters: does your home have one? - As you scroll down, the first two cards fold into two bubbles at the top. Tap a bubble to go back to its card. - The last card ends with a choice: "Yes, let's find out" starts the check; "Not for me" says goodbye and closes the app. - After your first check, the app opens on the last card, with the first two already folded. - The swipe-through pages and the circling drawing are gone; the six things you could host stay listed under the cards. - While a check runs, nothing is left empty: each thing you could host has its card from the start, with a "Checking" label and a moving shimmer, until its answer arrives. Checks still running look the same. - The question, the two answers and the goodbye are in every language; translations other than English and Italian are still drafts.

“me-web?”
Can you run your own server from here? “me-web?” checks your connection and your device and tells you, in plain words, what you could host at home, what stands in the way, and what would fix it.
Status: early development.
What it checks
“me-web?” draws the path from this device to the internet one step at a time (this device, your router, any shared exit of your provider, your provider, the internet), with the details it found for each, and groups what it checks under the step it concerns:
- whether you are online, or behind a login page;
- how this device is connected, and the address your router gave it;
- your public IPv4 and IPv6 addresses, and which device holds them;
- your provider, found offline in a built-in map, with what is usual for it (shared IPv4, an address of your own, IPv6, the mail port) and the source and date of each note;
- whether your router answers apps that ask it to open ports (UPnP, NAT-PMP, PCP), and which internet address it has;
- whether your provider shares your public IPv4 address with other customers (CGNAT) or there is a second router in the way;
- how your router translates addresses for calls and games (easy or hard NAT), with two STUN servers, and how it hands out ports, whether two devices behind it can reach each other, and how long it keeps an unused connection open; behind a provider's shared address, how many customers may share it;
- on mobile data, the operator and the type of network (5G, 4G), read from the phone itself;
- only if you agree: whether the outside world can actually reach this device, over IPv4 and IPv6, with the ports opened by your router for ten minutes and closed afterwards, and whether your own public address works from home (hairpin);
- whether this connection can send mail directly: port 25, the reverse name (PTR) and the blocklists, asked through your own name server;
- whether your name server checks signatures (DNSSEC) and answers honestly for names that don't exist;
- the speed and the round-trip time to the publisher's server, and whether this device makes a sensible server;
- which networks your provider reaches the internet through, and, with the test from outside, the route from the publisher's server back to your address;
- how your public address has changed across your earlier checks.
It ends with what that means: 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), or can't tell.
At the end you can choose to share your findings, after reading exactly what is sent, to improve the notes on providers; you can delete them from the app at any time, and they are deleted after twelve months (https://meweb.arasaka.software/privacy).
Planned: the builds for Mac announced once they have been tried on a real Mac.
Platforms
Linux (deb, rpm), Windows, macOS and Android. Builds are published as releases of this repository.
Privacy
“me-web?” sends nothing anywhere unless a check needs it, and lists every host it contacts ("What this app contacts" in the app). It has no telemetry, no analytics and no crash reporting. Your checks are kept on your device only, unless you choose to share them.
Verifying the Android app
The APK is signed with the key whose certificate SHA-256 is
5f:52:cf:f4:f5:2f:4e:0b:6d:a6:cd:04:4b:fc:ea:f7:8d:1d:42:db:24:f2:47:06:02:db:7f:19:cb:fd:f8:46
(apksigner verify --print-certs MeWeb-<version>-android.apk). Every release also carries SHA256SUMS.txt.

Translations other than English and Italian are machine drafts until someone reviews them. Corrections are welcome as issues on this repository. Nauruan and Palauan are missing: no draft good enough to ship could be written, and a speaker's help would put them in.
