Hysteria2, VLESS and WireGuard in plain words

what a VPN protocol is, why your subscription has several servers, and why you usually don’t need to choose

3 min read

A VPN protocol is an agreement on how your device and the server build an encrypted tunnel: how they recognize each other, how they encrypt data and what they do when the connection drops. The protocol decides how a VPN behaves on a good network and on a bad one.

what’s inside a vverh subscription

When you add vverh to Happ, the app gets a list of servers, not just one. It includes servers in Finland and the Netherlands on different protocols. The list updates itself: when we add a server, you get it the next time the subscription refreshes.

Hysteria2: for imperfect networks

Hysteria2 is built on QUIC, a modern way of moving data over UDP. Its key strength is holding its speed where the connection loses packets: mobile data, crowded café Wi‑Fi, a train, a cottage at the edge of coverage.

Classic TCP-based protocols slow down sharply when packets get lost and wait for things to recover. Hysteria2 keeps sending data at its own pace, so video and calls on a poor connection hold up longer. In the vverh subscription, Hysteria2 comes first.

VLESS: a solid backup

VLESS is a protocol from the Xray project. It runs over TCP, and your data is protected with TLS, the same encryption standard your bank’s website uses in the browser.

We run two flavors of VLESS: Vision and XHTTP. You don’t need to know the difference. They’re backup servers in case UDP works poorly on some network and Hysteria2 won’t connect.

WireGuard and AmneziaWG

WireGuard is a fast, simple protocol built into many systems and routers. AmneziaWG is a variant of it from the Amnezia project. We started with AmneziaWG, and now we connect through Happ and other subscription apps: it’s easier to add new devices, and servers and your term update on their own. We still issue AmneziaWG keys by arrangement with support if you really need them.

which one to pick

None, leave it as it is. Happ connects to the first server on the list. Choosing by hand only makes sense if:

  • the first server won’t connect on this network: take the next one;
  • speed is lower than usual: compare with another server, and run through the checks in why a VPN is slow.

in short

  • a protocol is the set of rules for building the tunnel;
  • Hysteria2 is fast on unstable networks and first on our list;
  • VLESS (Vision and XHTTP) are backup servers over TCP;
  • WireGuard and AmneziaWG are available by arrangement;
  • you usually don’t need to choose by hand.
