grpcurl vs ProtoCall
Both stand on grpc tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacSelf-hosted+1
Choose grpcurl when you need a free command-line way to invoke gRPC methods, inspect schemas, or work with streaming RPCs. If a server has no reflection, you will need its proto source files or a protoset file to provide the schema.

ProtoCall organizes gRPC-related proto files in browser-based workspaces and offers both GitHub and manual import paths. Teams needing a workspace spanning multiple repositories should note its current single-repository limit.
