Type: Feature Request
protobuf decoder for requests and responses
Like the JSON and XML tabs, there should be a Protobuf tab that offers to decode protobuf requests and responses.

Here is my extension to parse Protobuf:

You can use third party inspectors or make one on your own to support it, as it would require additional schema data to help decode the protobuf data. You can refer to one such project on github at https://github.com/tweshlyallpuri/ProtobufInspector/

It's too bad because I love fiddler but instead purchased a Charles license because this feature was missing.

The compiled version of ProtoMiddler is no longer available and the solution isn't compilable anymore as the libraries have changed it's API. Some basic support for Protobuf in Fiddler would really be appreciated.

I face with Protobuf http requests and responces very often and always have to use protoc.exe -raw_decode.

Would be very happy to see protobuf decoder built-in Fiddler.

Look at how Charles proxy does it: https://www.charlesproxy.com/documentation/using-charles/protocol-buffers/

Works pretty well in practice.

Protobuf is somewhat more complicated than XML and JSON as you need a scheme to parse the data.

See https://github.com/SecurityInnovation/ProtoMiddler for a third-party implementation.
