Why grpc-web and not native gRPC?

Browsers cannot speak HTTP/2 gRPC directly; grpc-web wraps calls over HTTP/1.1 or HTTP/2 with a compatible gateway.

What if calls fail with CORS?

Your grpc-web proxy must expose CORS headers and translate requests from the browser.

Is my data uploaded when I use gRPC Client?

No. gRPC Client runs entirely in your browser. Your input never leaves your device.
