+    \qmlproperty bool protobuf.cpp::useGrpc
+
+    Whether to use gRPC framework.
+
+    Use this property to enable support for the modern open source high performance RPC
+    framework by Google, gRPC (\l{https://www.grpc.io}).
+
+    A simple qbs file that uses grpc can be written as follows:
+    \code
+    CppApplication {
+        Depends { name: "protobuf.cpp" }
+        protobuf.cpp.useGrpc: true
+        files: ["main.cpp"]
+        Group {
+            files: "grpc.proto"
+            fileTags: "protobuf.grpc"
+        }
+    }
+    \endcode
+
+    \note that \c protobuf.grpc tag should be assigned manually because gRPC uses same \c *.proto
+    files and \QBS can't detect whether to generate gRPC or \c protobuf.
+
+    The following \c grpc.proto file...
+    \code
+        syntax = "proto3";
+
+        package Qbs;
+
+        message Request {
+            string name = 1;
+        }
+
+        message Response {
+            string name = 1;
+        }
+
+        service Grpc {
+            rpc doWork(Request) returns (Response) {}
+        }
+    \endcode
+
+    ...can be used in the C++ sources as follows:
+    \code
+        #include <grpc.grpc.pb.h>
+
+        class Service final : public Qbs::Grpc::Service
+        {
+            grpc::Status doWork(
+                    grpc::ServerContext* context,
+                    const Qbs::Request* request,
+                    Qbs::Response* reply) override
+            {
+                (void)context;
+                reply->set_name(request->name());
+                return grpc::Status::OK;
