gRPC tools

Free, and they run in your browser: nothing you paste is sent anywhere.

• gRPC status code lookup

  Look up any gRPC status code by number or name, such as 14 or UNAVAILABLE: what it means, what usually causes it and what to check. All 17 codes, one page each.

• grpcurl command builder

  Build a correct grpcurl command from a form: host, method, JSON body, metadata, TLS or mutual TLS, deadline and .proto files. Runs in your browser; nothing is sent.

• .proto to JSON request template

  Paste a .proto message or service and get the JSON request skeleton to send with grpcurl, Postman or istek, following the proto3 JSON mapping. Runs in your browser.

• Protobuf decoder

  Decode protobuf bytes online without the .proto file. Paste base64 or hex and see field numbers, wire types, strings and nested messages. Runs in your browser.
