AI 产品解读CORS proxy browser extension for Hoppscotch API development platform — routes HTTP requests through the extension's background service worker to bypass Cross-Origin Resource Sharing restrictions
When using Hoppscotch (an open-source API testing tool) in the browser, CORS policies prevent sending requests to many APIs. This extension removes those restrictions by acting as a privileged intermediary that can make cross-origin requests on behalf of the web app.
1. Install extension from Chrome Web Store. 2. Open Hoppscotch web app (https://hoppscotch.io or self-hosted instance). 3. Extension content script auto-injects a hook (__POSTWOMAN_EXTENSION_HOOK__) into allowed pages. 4. When user sends an API request in Hoppscotch, the web app communicates via window.postMessage to the content script. 5. Content script relays the request to the background service worker via chrome.runtime.sendMessage. 6. Background worker executes the fetch with <all_urls> permissions (bypassing CORS) and returns the response. 7. Popup UI allows managing which origin domains are trusted for the hook.

- 目标用户
- Developers and QA engineers using Hoppscotch for API testing and development / Front-end developers testing REST/GraphQL APIs from the browser
- The extension destination (hoppscotch.io) may have its own account system for saving collections/environments, but this is outside the extension's scope and does not affect its core CORS-bypass functionality.
- Source code is minified/bundled (Parcel), making exact line-by-line tracing harder, but the logic is clear and well-structured.

The extension is entirely free and open source (GitHub: hoppscotch/hoppscotch-extension). All 'subscribe' keyword hits are from a Proxy-based reactive programming pattern (defineSubscribableObject with _subscribers/subscribe for property change observation), not subscription/payment. All 'pro' keyword hits are from generic code patterns like Object.defineProperty, Proxy, processRequest, etc. No billing APIs, payment UI, feature gating, or payment processors (Stripe, etc.) exist in the code. Hoppscotch.io has a separate paid teams/enterprise plan, but the extension itself gates no features behind payment.

- The extension contains no login UI, no authentication APIs, and no credential storage. It operates purely as a utility layer that injects hooks into web pages and proxies HTTP requests through its background service worker. No account or authentication is needed to use the extension's core CORS-bypass functionality.
