## What it is
A Chrome browser extension that redirects requests to Google CDNs (fonts, libraries, reCAPTCHA, Gravatar) to China-accessible mirror domains. It uses the browser's webRequest/declarativeNetRequest APIs to rewrite request URLs.

## Use cases
- speed up websites that load assets from Google CDN in China
- replace Google fonts CDN with a China mirror
- fix reCAPTCHA loading in mainland China
- redirect Gravatar avatars to a mirror
- swap jQuery and Bootstrap CDN requests to domestic mirrors

## When to choose
- you browse from mainland China and sites hang on Google-hosted assets
- you want a browser-level fix without editing hosts files or proxies

## When to avoid
- you are outside mainland China and Google CDN is fast
- you need to redirect CDNs other than the supported list
- you use a browser without WebExtension request-redirect APIs

## Facets
- artifact type: plugin
- maturity: active
- function: proxy, networking, developer-tools
- domain: browser-extensions, web-development, censorship-circumvention, privacy
- platform: browser, browser-extension
- tags: chrome-extension, cdn-redirect, google-cdn, china-mirror, webrequest, declarativenetrequest
