Enterprise-scale gRPC Schema Relationship Visualizer
Drag & Drop .proto files
Supports multiple files for dependency mapping

Why use Protobuf Viewer?
Visual Hierarchy Scaling
Enterprise gRPC architectures often involve thousands of lines of `.proto` code spread across multiple files. Protobuf Viewer scales with your architecture, transforming raw text into an organized, searchable dependency map that highlights nested objects and circular references.
Zero-Backend Privacy
Unlike server-side decoders, all parsing and visualization happen locally in your browser. This makes it safe for corporate use where proprietary schemas and confidential binary trace data must never leave the machine.
When to use gRPC Visualizer?
Architectural Onboarding
When joining a new team or microservice project, reading raw Protobuf definitions is tedious. Drag and drop the schema repository into Protobuf Viewer to immediately understand how services, requests, and responses interact across the system.
Contract Validation
Validate that your Base64 or Hex binary payloads match your actual schema definitions. The Binary Debugging Hook provides an instant "Mirror View," decoding live traffic directly into the visualized tables.
Frequently Asked Questions
Does it support multi-file imports?
Yes. You can drag and drop multiple `.proto` files at once. The viewer will attempt to resolve cross-file dependencies and imports locally, mapping relationships across your entire repository.
How does binary decoding work?
We use a heuristic approach combined with the currently loaded schema. If multiple messages are present, we attempt to decode using the primary message type (usually the one with the most fields).
Is my schema data saved?
No. All data is stored purely in React state and is cleared upon page refresh. We do not use any persistent storage or cookies for your schemas or binary inputs.
