AnyProxy

English ｜ 简体中文

AnyProxy is a powerful Chrome extension that allows you to easily redirect network resources without server-side modifications. It provides a flexible way to forward any web requests to different destinations using regex-based rules.

Key Features:

• Simple Configuration: Set up forwarding rules with regex patterns
• No Server Changes: Redirect requests without modifying the target server
• Real-time Updates: Rules take effect immediately without browser restart
• Developer Friendly: Perfect for local development and testing
• Resource Types: Support for JavaScript, CSS, and API

Perfect for:

• Frontend developers testing local changes
• QA engineers comparing different versions
• Debug and troubleshoot network issues
• A/B testing without server deployment

Usage

The proxy configuration consists of two parts in each array element:

• First value corresponds to regexFilter
• Second value corresponds to regexSubstitution

For detailed information, please refer to:

• regexFilter documentation
• regexSubstitution documentation

Note: The only difference is that capture group references in regexSubstitution are changed from \1-\9 to $1-$9.

Example Configuration

  "proxy": [
    [
