Description
A Chrome DevTools extension for debugging gRPC-Web requests. Capture, Repeat, and Edit & Repeat without uploading proto files. gRPC-Web DevTools for QA adds a dedicated panel to Chrome DevTools for inspecting and debugging gRPC-Web network requests — designed especially for QA engineers who need to replay and modify API calls without backend access. —————————————————— KEY FEATURES —————————————————— ▸ Zero-config Capture Automatically captures gRPC-Web requests as JSON as soon as the page loads. No setup, no proto file upload required. ▸ Repeat Resend any captured request with one click. Authentication headers and session context are preserved automatically. ▸ Edit & Repeat Modify request fields directly in the JSON editor and resend. No proto file needed — the app's own compiled types handle encoding behind the scenes. ▸ Proto File Upload (Optional) Upload .proto files to enable response decoding, field type hints, and grpcurl command generation for terminal use. ▸ Request Templates Save frequently used requests as templates and reload them across sessions. ▸ Load Testing Send the same request repeatedly with configurable concurrency to simulate load. ▸ Streaming Visualizer Inspect server-streaming RPC responses message by message in real time. —————————————————— SUPPORTED LIBRARIES —————————————————— • @improbable-eng/grpc-web • @connectrpc/connect-web • @protobuf-ts/grpcweb-transport —————————————————— SOURCE —————————————————— Based on SafetyCulture/grpc-web-devtools (MIT License). Extended with QA-focused features including proto-free Edit & Repeat and protobuf-ts support.
