See the **[Wiki](https://github.com/FrankoonG/hy2scale/wiki)** for full installation, configuration, and API documentation.

## Quick Start

### One-liner (native binary, systemd)

```bash
curl -fsSL https://raw.githubusercontent.com/FrankoonG/hy2scale/main/install.sh | sudo sh
```

Auto-detects the CPU architecture (`amd64`, `arm64`, `armv7`, `mips64le`,
`mipsle-softfloat`), downloads the matching tarball from the latest
release, installs the binary to `/usr/local/bin/hy2scale`, and registers
a systemd service. Re-running upgrades in place. Pin a version with
`HY2SCALE_VERSION=v1.3.3`; uninstall with `… | sudo sh -s -- --uninstall`.

### Docker

Full mode (host network — everything enabled):

```bash
docker run -d --name hy2scale \
  --network host --privileged \
  -v hy2scale-data:/data \
  --restart unless-stopped \
  frankoong/hy2scale:latest
```

Bridge mode (VPN + proxies, no routing rules):

```bash
docker run -d --name hy2scale \
  --cap-add NET_ADMIN --cap-add NET_RAW \
  --device-cgroup-rule="c 10:200 rwm" \
  --device-cgroup-rule="c 108:0 rwm" \
  -p 5565:5565/tcp -p 5565:5565/udp \
  -p 500:500/udp -p 4500:4500/udp -p 1701:1701/udp -p 51820:51820/udp \
  -v hy2scale-data:/data \
  --restart unless-stopped \
  frankoong/hy2scale:latest
```

The two `--device-cgroup-rule` lines grant access to `/dev/net/tun` (relay
packet capture) and `/dev/ppp` (L2TP/IPsec PPP layer). Without `c 108:0 rwm`,
L2TP tunnels establish IKE+ESP successfully but pppd exits before assigning
an IP, so clients see "Connected" briefly then disconnect. Full mode skips
this because `--privileged` grants every device.

Open `http://<host>:5565/scale/` — default login `admin` / `admin`.

For iKuai v4, download the `.ipkg` from [Releases](https://github.com/FrankoonG/hy2scale/releases) and install via the app store — see the [iKuai v4 guide](https://github.com/FrankoonG/hy2scale/wiki/iKuai-v4-Installation).

## Features

- Connect nodes into a mesh and route traffic through any of them.
- See live topology and latency in an interactive graph or a table view.
- Run VPN / proxy services: Hysteria 2, SOCKS5, HTTP, Shadowsocks, L2TP, IKEv2, WireGuard.
- Per-user exit routing, traffic limits, expiry, bulk management.
- IP and domain routing rules steer specific traffic through specific exits.
- TLS certificate management with built-in CA signing.
- Multi-IP peer aggregation (failover or bandwidth bonding).
- Backup / restore, in-place binary upgrade (manual or one-click online check), UI in EN / 中文 / 한국어.
- Select-to-edit UX: pick a row in any list and a top-right **Edit** button drives editing; clicking blank area outside the list clears the single selection; hysteria2:// share URLs can be imported by long-pressing **+ Add Node**.
