Product summary

Review the store description, core capabilities, and common use cases.

CORS Unlocker is a developer-focused Chrome extension designed to help you test APIs and frontend integrations by temporarily bypassing Cross-Origin Resource Sharing (CORS) restrictions during development.

The extension works locally on your browser and only modifies request headers for the websites you explicitly enable. It does not collect, store, or transmit any personal or sensitive data.

Key Features

- Toggle CORS rules on/off with a single click

- Add custom domains to enable CORS for specific sites

- Automatically injects required development headers
