How it works
CORS Header Generator helps configure cross-origin access rules for APIs and web apps. It reduces integration errors by clarifying allowed origins, methods, and headers. Use least-privilege rules and avoid permissive wildcard setups for sensitive endpoints.

FAQ
Is Access-Control-Allow-Origin: * always safe?
No. It can be risky for authenticated or sensitive endpoints and should be scoped carefully.
Does CORS protect APIs from abuse?
