## What it does

Build grpcurl commands for native gRPC and test gRPC-Web endpoints from the browser. Native gRPC uses HTTP/2 features that browsers do not expose directly, so browser requests here are explicitly gRPC-Web requests.

## Use the tool

Open https://ilham.dev/tools/grpc-tester/, add the input the tool asks for, run it, and check the output before using it elsewhere.

## Input and output

- Input: text.
- Output: text.
- Category: Network.

## Privacy and processing
This tool needs a network request to complete the lookup or test. Send only data you are comfortable sharing with the target service.

## Questions

### Can a browser call native gRPC?

Not directly. Browsers can use gRPC-Web through a compatible server or proxy. For native gRPC, use the generated grpcurl command from a terminal.
