gRPC is Google's open-source RPC framework for building efficient network services on both the server and the client.

With a gRPC service, you can make efficient network requests to and from your clients. gRPC was created to help solve the common issues of synchronous network services. It also enables you to run your gRPC service in a background thread and then process the data on the main thread, instead of blocking the main thread for the entire duration of a request.

gRPC-Web is a DevTools extension that allows you to see the JSON serialization of your gRPC request logs in your Chrome browser.
