Tested it with common gRPC cases. Just some things why it's not good for gRPC:
1. It doesn't support streams.
2. It doesn't support "include directories" option.
3. It doesn't support Server-Side/Mutual TLS with custom
certificates.
4. When I entered URL like 0.0.0.0:4000 app freezes and won't work, so I can't send any request.
5. I think it support only gRPC-Web, because my URL 0.0.0.0:4000 converts to http://0.0.0.0:4000. If yes, it only covers gRPC-Web that is not fit all user needs.
