How to Use Sublink

Sublink generates V2Ray-compatible subscription links. Give it your proxy config and a set of IPs, and it creates subscription URLs you can import into V2RayNG, V2RayN, Clash, or any compatible client.

Who is this for?

Anyone managing multiple proxy servers across different IPs. Instead of configuring each one manually, Sublink generates all configs at once and packages them into a single subscription link.

Supported Protocols

Protocol	Prefix	Description
VMESS	vmess://	V2Ray default protocol
VLESS	vless://	Lightweight V2Ray protocol
Shadowsocks	ss://	Classic proxy protocol
Trojan	trojan://	TLS-based protocol
Hysteria2	hysteria2://	QUIC-based high-speed protocol

Step by Step

1. Get your config URI — Copy the link from your provider (vmess://, vless://, ss://, trojan://, or hysteria2://).
2. Choose input method — Enter an IP range manually, or upload a .txt file with one IP per line.
3. Paste your config — Put the full URI into the config field.
4. Generate — Click the button. Sublink creates a config for each IP.
5. Copy the link — Use the "Copy Link" button on the results page and add it as a subscription source in your client.

Importing into V2RayNG

1. Open V2RayNG on your device.
2. Tap + and select Import from subscription.
3. Paste the Sublink subscription URL.
4. Tap Update subscription to fetch configs.

Tips

• For CDN configs, use Cloudflare or Fastly IP ranges shown on the generator page.
• The IP file should have one IP per line. Sublink extracts all valid IPv4 addresses.
• Large ranges are paginated (1000 configs per page) for client compatibility.
• Each subscription gets a unique persistent URL you can share.

REST API

Sublink also has a JSON API at /api/v1/. Use POST /api/v1/generate with {"config": "...", "start_ip": "...", "end_ip": "..."} for programmatic access. See GET /api/v1/health and GET /api/v1/protocols to get started.
