A web-based interface for exploring and interacting with gRPC services through reflection.

• Node.js 14.0 or higher
• Yarn package manager
• grpcurl (brew install grpcurl on macOS)

git clone <repository-url>
cd grpcWebExplorer
yarn install

yarn dev

Access at http://localhost:3000

yarn build:prod
yarn start

docker-compose up -d

Access at http://localhost:3000

docker-compose up -d     # Start container
docker-compose logs -f   # View logs
docker-compose down      # Stop container

1. Click "Add Network"
2. Enter gRPC endpoint (e.g., grpc.example.com:443)
3. Configure TLS if needed
4. Services will be discovered automatically via reflection

1. Select a method from the left panel
2. Enter parameters in JSON format on the right panel
3. Click "Execute"
4. View response below

The interface has resizable panels:

• Left: Service/method tree
• Top: Method descriptor
• Center: Selected methods
• Right: Parameters and results

Drag the dividers to resize panels according to your needs.

• Ctrl/Cmd + N: Add network
• Ctrl/Cmd + K: Show shortcuts
• Ctrl/Cmd + H: Execution history
• Ctrl/Cmd + W: Close tab
• Ctrl/Cmd + Tab: Switch tabs

• grpc.juno.basementnodes.ca:443
• grpc.noble.basementnodes.ca:443
• grpc.neutron.basementnodes.ca:443
• grpc.cosmos.directory:443

All use TLS by default. For local nodes, typically use port 9090 without TLS.

pm2 start ecosystem.config.js
pm2 save
pm2 startup

Copy systemd.service to /etc/systemd/system/grpc-explorer.service and:

systemctl enable grpc-explorer
systemctl start grpc-explorer

# macOS
brew install grpcurl

# Linux
go install github.com/fullstorydev/grpcurl/cmd/grpcurl@latest

• Verify endpoint: grpcurl <endpoint> list
• Check TLS settings match server
• Ensure server has reflection enabled
