Switchy Proxy

About

Switchy Proxy is a Chrome extension for developers to manage and debug URL proxy rules efficiently. Key features include:

•  URL Redirection: Regex-based rules for environment switching and resource replacement.
•  CORS Management: Enable CORS for specific domains to resolve cross-origin issues.
•  Error Monitoring: Logs failed requests with detailed reasons (e.g., CSP violations, network errors).
•  Rule Import/Export: JSON-based rule sharing and backup.
•  Dynamic Rules: Powered by Chrome's Declarative Net Request API for efficient rule handling.

Ideal for debugging and managing network requests with ease.

Rules JSON file example:
{
  "proxy": [
    [
      "https://api.example.com/v1/(.*)",
      "http://localhost:3000/api/v1/$1"
