A tool to visualize .proto file hierarchies
Project description
Proto Explorer
A lightweight, interactive browser for exploring Protobuf/gRPC hierarchies
Proto Explorer lets you visually explore Protobuf message hierarchies (*.proto files) using only the compiled Python files (*_pb2.py). No .proto files or regeneration required.
✅ Expand nested message fields
✅ Show oneof group hierarchy
✅ Correctly detect map<key, value> fields
✅ Load _pb2.py from custom paths
✅ No server or DB needed — runs locally
🌟 Demo Screenshot
Coming soon – add screenshot here once UI finalized You can insert a screenshot like:
