This tool provides a clear, reliable, and instant environment to verify if a server is correctly configured to accept requests from specific origins. Unlike generic API clients, NOVA CORS Tester is purpose-built to analyze the specific HTTP headers that control resource sharing. It sends real requests from the browser and parses the response headers to provide a definitive "Allowed" or "Blocked" status. With a clean, professional interface, it breaks down complex header configurations into easy-to-read reports, helping you identify missing headers, incorrect origins, or rejected methods in seconds. The full version stays on the original page, which this listing opens directly.
