Proxy Builder

🌐 فارسی | English

A powerful, standalone web application with two tools:

1. 🧬 Fragment + Fingerprint — enhance a VLESS or Trojan URL by injecting cs (cipher suites), fm (fragment mask) and fp (TLS fingerprint) parameters, plus a server (IP/domain) override — producing a link ready to import into your own client.
2. 🔗 Chain Builder — chain two proxy configurations into a single Xray or Sing-box JSON configuration for enhanced connection stability and fixed IP masking.

All processing happens in your browser. No data is sent to any server.

🚀 Features

🧬 Fragment + Fingerprint

• Paste & Enhance: Paste single or multiple vless:// or trojan:// URLs (one per line) and get enhanced links with cs, fm and fp parameters added.
• Multi-Config Support: Paste bulk proxy URL lists to parse, validate, and batch enhance all URLs cleanly without remark collision.
• Server Override: The server (IP/domain) field is auto-filled from the URL for a single config and is user-editable. With multiple configs the field stays empty and only applies to all configs if you type a custom value (supports IPv4, IPv6 and domains).
• Fingerprint: Default unsafe, with chrome, firefox, safari, random and none options.
• TLS-aware: cs and fm are only added when the config uses tls security. Clear a field to skip that parameter.
• One-click Copy: Copy the enhanced URL straight to the clipboard.
• Protocol Support: VLESS and Trojan.

🔗 Chain Builder

• Dual Config Chaining: Easily chain a primary proxy (e.g., Worker/CDN) with a secondary chain proxy.
• Protocol Support: Supports VLESS, VMess, Trojan, Shadowsocks, SOCKS, HTTP, and SSH.
• Dual Output: Generates both Xray and Sing-box JSON configurations.
• ECH Support: Automatically parses and includes ECH config for secure connections.

Output	Client
Xray JSON	Use with any Xray-compatible client (v2rayN, v2rayNG, Nekoray, etc.)
Sing-box JSON	Nested tabs for different client types (see below).

📦 Sing-box Sub-formats

• Standard: The regular Sing-box configuration.
• Nekoray: High compatibility format optimized for Nekoray.
• Nekobox (Android): Optimized for Android with a TUN inbound, ensuring proper VPN recognition (key icon) and mobile stability.

🔗 How the Chain Builder Works

The application generates a configuration that routes your traffic in this sequence:

You ➔ Config 1 (Proxy) ➔ Config 2 (Chain) ➔ Internet

This ensures that your final outgoing IP address is that of the Chain Proxy, providing a consistent identity for the websites you visit.

🛠️ Usage

🧬 Fragment + Fingerprint

1. Switch to the Fragment + Fingerprint tab.
2. Paste your VLESS or Trojan URL.
3. Adjust the options if needed: server override (auto-filled from the URL), fingerprint, cipher suites, final mask.
4. Click "Enhance URL" and copy the resulting link — import it into your client.

✅ Client Requirements

• Windows: use v2rayN version 7.24.7 or higher.
• Android: use PattNG or v2rayNG version 2.3.4 or higher.

🔗 Chain Builder

1. Config 1: Paste your first proxy URL (this can be a Cloudflare Worker, CDN, or any other proxy).
2. Config 2: Paste your second proxy URL (the one you want to chain through).
   • For SSH, click the 🔑 SSH toggle and fill in server, port, username, and password.
3. Settings: Adjust DNS servers or SOCKS ports if needed.
4. Generate: Click "Generate Chained Config" to get your JSON.
5. Deploy: Copy the JSON or download it as a file to use in your preferred client.

📋 Supported Protocols

Protocol	URL Format	Notes
VLESS	vless://uuid@server:port?params	Supported by both tools
VMess	vmess://base64-json	Chain Builder only
Trojan	trojan://password@server:port?params	Supported by both tools
Shadowsocks	ss://base64(method:pass)@server:port	Chain Builder only — no transport (ws, grpc, etc.) and no TLS support
SOCKS	socks://user:pass@server:port	Chain Builder only — must include username and password
HTTP	http://user:pass@server:port	Chain Builder only — must include username and password
SSH	4-field input (server, port, user, password)	Chain Builder only — Sing-box only, not supported by Xray

⚠️ Important Notes

• The Fragment + Fingerprint tool supports VLESS and Trojan URLs only.
• TLS is required: the Fragment + Fingerprint tool only works with configs that have TLS enabled (security tls or reality). Non-TLS configs are not supported and will not work.
• cs (cipher suites) and fm (final mask) are only added when the config uses tls security.
• SOCKS & HTTP configs must have username and password included.
• Xray does not support raw (headerless TCP) configs — use TCP with http header type instead.
• Shadowsocks cannot have any transport (WebSocket, gRPC, HTTPUpgrade, etc.) and cannot have TLS.
• SSH is only supported by Sing-box. When SSH is used, the Xray tab is automatically disabled. Use the sing-box client for SSH configs.

🔧 Supported Transports

TCP, TCP (http header), WebSocket, gRPC, HTTPUpgrade

🔒 Supported TLS

TLS, Reality, None

📦 Tech Stack

• HTML5: Semantic structure.
• CSS3: Custom variables, glassmorphism, and animations.
• JavaScript: Core logic for URL parsing, enhancement and JSON generation.

🛡️ Credits

• The Fragment + Fingerprint enhancement logic (cs / fm / fp injection and URL export format) is based on the PattNG project's export-to-clipboard behavior.
• The Chain Builder draws inspiration and logic from the BPB-Worker-Panel project and this Sing-box configuration.
