WebSocket Tester

Test and monitor WebSocket connections in real-time. Send messages, analyze performance, and validate your WebSocket implementations.

WebSocketReal-timeConnection TestingPerformance Metrics

Quick Start

Getting Started
  1. Enter a WebSocket URL in the connection panel (default:wss://echo.websocket.org)
  2. Click the Connect button to establish a connection
  3. Use the message input to send text or JSON messages
  4. View real-time metrics and message logs in the respective tabs

  • Connection status monitoring
  • Quick connection presets for popular servers
Message Handling
Send and receive WebSocket messages
  • Send text and JSON messages
  • Real-time message logging
  • Filter messages by type (sent, received, error, system)
  • Search through message history
  • Export messages to JSON
Performance Metrics
Monitor connection health and performance
  • Real-time latency tracking
  • Message count statistics
  • Error monitoring and reporting
  • Connection uptime tracking
  • Visual health indicators
Advanced Testing
Comprehensive testing capabilities
  • Predefined test scenarios (ping-pong, JSON, binary, load)
  • Stress testing with configurable parameters
  • Message templates for common scenarios
  • Performance benchmarking tools
  • Custom test scenario creation

Usage Guide

Connection Panel

Configuration Options

  • URL: Enter the WebSocket server URL (e.g., wss://echo.websocket.org)
  • Reconnect Attempts: Number of reconnection attempts (0-10)
  • Reconnect Interval: Time between attempts (500ms - 10s)
  • Auto Reconnect: Toggle automatic reconnection

Quick Connect Presets

  • Echo Server: wss://echo.websocket.org - Echoes back all messages
  • Postman Echo: wss://ws.postman-echo.com/raw - Postman's echo service
  • SocketsBay Demo: wss://socketsbay.com/wss/v2/1/demo/ - Demo WebSocket server

Example Workflows

Testing a Chat Application
  1. Connect to your WebSocket server URL
  2. Use the "Authentication" template to send login credentials
  3. Use the "Subscribe" template to join a chat room
  4. Send test chat messages using the "Chat Message" template
  5. Monitor the Metrics tab for latency and error rates
Testing Real-time Data Streaming
  1. Connect to your data stream WebSocket endpoint
  2. Run the Ping/Pong test to verify connection stability
  3. Use the Load Test scenario to check high message volume handling
  4. Filter message logs to view received data only
  5. Export message history for further analysis

Tips & Best Practices

Do

  • Use WSS for production connections
  • Test with echo servers first
  • Monitor latency during testing
  • Use stress tests in staging environments
  • Export logs for debugging

Don't

  • Don't stress test production servers
  • Don't ignore error messages
  • Don't use WS for sensitive data
  • Don't skip connection testing
  • Don't forget to disconnect when done
