Fire test RPC calls and watch them get decoded in real time. Same decode logic arpeesee runs locally, minus the Chrome extension in the middle.
Simulated gRPC-web and Connect RPC calls decoded into readable field names. The real app does the same thing except it intercepts actual calls from your browser.
The Chrome extension captures calls automatically as you use your app. No buttons to click. Every RPC call from every tab appears in the panel.
Point arpeesee at your local .proto files and it decodes your own services' calls — not just this toy example. All fields, all types, nested messages too.
