CORS Unblock

Temporarily unblock CORS for development and testing purposes

CORS Unblock – Disable CORS for Development & Testing The easiest way to disable CORS restrictions in Chrome during local development and API testing. Toggle CORS off instantly with one click, a keyboard shortcut, or a right-click — no browser restart, no command-line flags needed. KEY FEATURES: - One-click toggle to enable/disable CORS bypass - Keyboard shortcut: Alt+Shift+C (Option+Shift+C on Mac) - Right-click the extension icon to toggle without opening the popup - Toolbar icon and badge show live status — green (unblocked) or grey (blocking active) - State persists across page reloads until you turn it off - Auto turn-off when browser closes — never accidentally leave it on - Supports localhost and private network requests (192.168.x.x etc.) - Exposes response headers so JS can read them after unblocking - Built-in security reminder so you never forget to turn it off BUILT FOR DEVELOPERS Perfect for frontend developers, QA engineers, and API testers working with cross-origin requests during local development, staging, or debugging sessions. USE RESPONSIBLY Disabling CORS bypasses an important browser security mechanism. Only use on trusted sites and always turn it off when done. The auto turn-off on browser close ensures you're never left exposed. Completely free. No ads. No data collection. For JSON Validation and formatting visit: https://jsonvalidator.onrender.com
