CORS Bypass is a specialized Chrome extension designed to help developers bypass Cross-Origin Resource Sharing (CORS) errors on a per-site basis. Unlike traditional CORS extensions that apply globally, this tool allows users to enable CORS only for selected domains, ensuring that other tabs remain unaffected. Notably, it operates with zero CPU overhead when disabled, making it a lightweight solution for frontend testing against various APIs without compromising browser performance.

Key features include a smart domain protection list to prevent accidental overrides, full support for CORS headers, and a debug panel that provides real-time insights into modified requests. The extension also boasts privacy features such as no data collection and offline functionality. With customizable settings and a user-friendly interface, CORS Bypass proves to be an essential tool for developers requiring efficient and reliable CORS management.
