gRPC Proto Files

Proto files (.proto) are the foundation of gRPC services, defining the contract between clients and servers. Bruno supports adding proto files to enhance your gRPC development experience with better IntelliSense, method discovery, and type safety.

Proto File Options

You have two ways to add Proto files for enhanced IntelliSense and method discovery:

Option 1: Request Level

1. Open your gRPC request in Bruno
2. In the gRPC interface, locate the Using Reflection section
3. Click on the Browse for proto file button or toggle the proto file option
4. Click the file browser to select .proto files from your local system

Option 2: Collection Level

1. Go to collection level settings
2. Navigate to the gRPC tab
3. Click the Browse for proto files to select .proto files from your local system

Add Proto files at the collection level for reuse across all requests.

Bruno will validate that the selected files are valid proto files. You can add multiple proto files if your service uses imports or multiple definitions.
