Happ Plus

Happ Plus brings up a VPN on a key you already have, and measures what your connection actually does — the speed, the delay, the DNS, and the parts of the internet your network refuses to carry.

VPN • Runs on your own key or subscription address. The app sells no access, operates no servers, and has no relationship with the one you connect to • Xray core: VLESS (including REALITY), VMess, Trojan, Shadowsocks and SOCKS5 • Servers from your subscription in one list, each with its flag, protocol and transport • One button to connect. No account, no sign-up

SPEED • Download and upload over several parallel streams against Cloudflare's global edge, so the number describes your link rather than one distant server • Ping, jitter and packet loss measured at the TCP level • A live gauge and a graph of the whole run: a link that stutters looks different from one that is simply slow • Every run is saved with the network it was made on

DNS • Times the resolver this network handed you against Cloudflare, Google, Quad9 and AdGuard • Queries go straight to each resolver over UDP, for names that cannot be answered from any cache — so the comparison is real, not a cache hit • Shows which resolver is fastest where you are right now • Detects a filtering resolver and flags answers that differ from a public one's

YOUR NETWORK • Public address, operator and AS number, country and city as the internet sees them • Wi-Fi, cellular or wired, plus metered and data-saver status • Every interface on the device and the addresses it holds • Tunnel detection: whether traffic appears to leave through a VPN, a relay or Cloudflare WARP • IPv6 checked end to end, not just on paper

WHAT GETS OUT Probes the ports that decide what is possible here: HTTPS, HTTP, DNS over UDP, TCP, TLS and HTTPS, SSH and mail. If encrypted DNS is blocked on this network, or UDP does not leave at all, you will see it.

NO ACCOUNT, NO ADS, NO TRACKING Nothing to sign up for, no analytics, no advertising. Results and keys stay on the device and are never uploaded. The developer cannot see what goes through the tunnel — it is your server and your key.
