A simple, client-side web application to convert various proxy subscription links (VMESS, VLESS, Trojan, Shadowsocks, ShadowsocksR, Socks, HTTP/S) into a unified Sing-box JSON configuration, based on a customizable base template.

The application runs entirely in your browser using HTML, CSS, and JavaScript, requiring no server-side processing.

• Multi-Protocol Support: Convert VMESS, VLESS, Trojan, Shadowsocks (SS), ShadowsocksR (SSR), Socks (Socks5), and HTTP/S proxy URLs.
• Template Selection: Choose between different predefined Sing-box base templates to structure your final configuration (e.g., a v1.12-like complex template and a v1.11-like simple template).
• Config Customization: A detailed settings page allows you to easily modify common parameters within the chosen template, including:
  • Log Level and Timestamp
  • Inbound Listen Addresses and Ports (Mixed, TUN HTTP Proxy)
  • TUN settings (NAT, Auto Route, MTU)
  • DNS Servers (Remote/Proxy, Direct) and Cache settings
  • Routing settings (Final Outbound, Default Resolver, Auto Detect Interface)
  • Remote Rule Set settings (Enable/Disable, Download Detour, Update Interval)
  • Experimental/Clash API settings (Controller, UI URL, UI Download Detour, Cache File options)
• Automatic Tagging: Parsed proxies are assigned unique tags to avoid conflicts.
• Selector Integration: Converted proxies are automatically added to specific selector/urltest outbounds within the template (by default, outbounds tagged "proxy" and "Auto", if they exist and are of type selector or urltest).
• Intelligent DNS Adjustment: Basic logic to modify DNS rules if no domain-based outbound servers are successfully parsed (e.g., potentially removing rules that rely on remote DNS servers if they are unreachable via domain proxies).
• Clean Output: Automatically removes null and undefined values from the generated JSON config.
• Copy & Download: Easily copy the generated config to your clipboard or download it as a .json file.
• Responsive UI: Designed to be usable on both desktop and mobile screens.
• Client-Side: All processing happens in your browser. Your proxy details and configurations are not sent to any server.

1. Download the Files: Save the following three files into the same folder:
   • index.html
   • style.css
   • script.js
2. Open in Browser: Double-click index.html or open it with your preferred web browser.
3. Input Proxy URLs:
   • Select your desired base template from the "Choose Base Template" dropdown.
   • Paste your proxy URLs (one per line) into the "Input Proxy URLs" textarea.
   • Click the "Next: Configure Template" button.
4. Customize Template Settings:
   • Fill out or adjust the parameters in the form fields. The fields will show the default values from the template you selected in the previous step.
   • Click the "Reset Settings" button to revert all fields to the defaults of the currently selected template.
   • Click the "Generate Config" button when you are ready.
5. Generated Sing-box Configuration:
   • The final Sing-box JSON configuration will appear in the textarea.
   • Review the config.
   • Use the "Copy Config" button to copy the JSON to your clipboard.
   • Use the "Download Config" button to save the JSON as a file (.json).
   • Click "Back to Settings" if you need to make changes to the template parameters and regenerate.

your-project-folder/ ├── index.html - The main HTML file for the user interface. ├── style.css - Contains all the CSS for styling the UI. └── script.js - Contains all the JavaScript logic for parsing, template modification, UI interaction, and output.

• Base Templates: The core Sing-box templates are embedded directly within script.js (templateV1_12, templateV1_11). If you need to add a new template or fundamentally change the existing ones beyond the parameters exposed in the UI, you will need to edit script.js directly. Ensure any new template includes an outbounds array and preferably outbounds tagged "proxy" and "Auto" (of type selector or urltest) for automatic proxy insertion.
• Exposed Parameters: The script exposes a specific set of parameters in the settings form based on the provided templates. If your custom template has different parameters you want to expose via the UI, you would need to modify both the index.html (to add the form fields) and the script.js (populateSettingsForm and applySettingsToTemplate functions) to handle them.
• Parsing Logic: The parsing logic for each protocol is also in script.js within the v2rayToSing function. If you encounter URLs that aren't parsed correctly or need to support new protocols, this is where you would make modifications.
• Build Tools: The project uses pure client-side HTML, CSS, and JS. No build tools (like Webpack, Babel) are required.
