gRPC Message Viewer

gRPC payloads are Protocol Buffers, a compact binary format that is unreadable without the corresponding schema. When you are debugging an RPC, that opacity is the problem: a captured message tells you nothing until you can line it up against its .proto definition. This toolkit lets you load a schema, then decode, inspect, and pretty-print messages so the wire format becomes something you can actually read and reason about.

It goes beyond viewing. You can encode messages from structured input, explore the types and services a .proto file declares, diff two messages to see exactly which fields changed, and generate mock data that conforms to a schema for tests and local stubs. A Monaco editor provides syntax highlighting and a comfortable editing surface for both the proto definitions and the message content.

Because it all runs in the browser, schemas and messages stay on your machine — handy when you are working with internal service definitions you would rather not paste into a remote service. Use it as a quick inspector during debugging or as a scratchpad while you design a new message type.
