WebSocket connections power real-time web apps—from chat applications to live trading platforms. But when they break, debugging can be frustrating and time-consuming.
A WebSocket Echo Tester makes troubleshooting simple.
What Does It Do?
This tool connects to any WebSocket server and echoes back your messages in real-time. It's perfect for testing connections, validating message formats, and debugging issues before they reach production.
Why Developers Love It
Instant Validation: Quickly check if your WebSocket server is reachable and responding correctly.
Real-Time Testing: Send messages and see responses immediately—no complex setup required.
Format Testing: Experiment with JSON, plain text, or binary data to ensure your messages are properly formatted.
Zero Setup: Browser-based tool that works instantly—just enter your WebSocket URL and start testing.
Common Use Cases
- Test WebSocket APIs during development
- Validate third-party service connections
- Troubleshoot network and firewall issues
- Monitor connection stability
- Verify authentication mechanisms
How to Use It
- Enter your WebSocket URL (e.g.,
wss://echo.websocket.org) - Click Connect
- Send test messages and watch the real-time responses
- Monitor connection status and error messages
Beyond Basic Echo Testing
While echo testing is fundamental, our tool also helps with:
- Connection lifecycle management: Test how your application handles connection establishment, maintenance, and cleanup
- Error handling: Simulate various error conditions to ensure your application responds gracefully
- Message queuing: Understand how messages are handled when connections are temporarily unavailable
- Authentication testing: Verify that your WebSocket authentication mechanisms work correctly
