 We believe that `ent` + gRPC can be a great way to build server applications in Go. For example, to set granular access control to the entities managed by our application, developers can already use [Privacy Policies](https://entgo.io/docs/privacy/) that work out-of-the-box with the gRPC integration. To run any arbitrary Go code on the different lifecycle events of entities, developers can utilize custom [Hooks](https://entgo.io/docs/hooks/).
 
 Do you want to build gRPC servers with `ent`? If you want some help setting up or want the integration to support your use case, please reach out to us via our [Discussions Page on GitHub](https://github.com/ent/ent/discussions) or in the #ent channel on the [Gophers Slack](https://app.slack.com/client/T029RQSE6/C01FMSQDT53).
