Unpacks a protobuf blob so you can see it. Without a schema you still get "field 3, string, length 12"; give it a .proto and the numbers get names.

How to use it

  1. Paste the protobuf blob as base64 or hex
  2. Read the wire-format breakdown with no schema needed
  3. Add a .proto to attach names and types
  4. Check which field number is which

Common questions

Can it read a blob with no schema?
Yes. The wire format alone always gives you "field 3, string, length 12". The moment things go wrong is usually "what are these bytes", and that far is often enough.
What changes if I supply a .proto?
Field numbers gain names and types, so the output reads like a sentence.
Is the blob uploaded anywhere?
No. Even a value scraped out of a log never leaves your browser.
