Socket Inspector

Simulate edge cases, reproduce bugs, and uncover security vulnerabilities in WebSocket Applications.

✓ Custom Message Simulation: Send custom WebSocket messages to the UI or the server. Build your message and send it over any WebSocket connection on the page. Set the destination to "Client" to simulate a message sent from the server to the UI. Set the destination to "Server" to simulate a message sent from the UI to the server. ✓ Disconnect Simulation: Manually close WebSocket connections with standard close codes and custom reasons. Test your application's reconnect logic and error handling by simulating server disconnects without any backend changes ✓ WebSocket Traffic Inspection: View all sent and received messages in real-time. Search and filter to find exactly what you need. Supports both WS and WSS connections. ✓ Traffic Blocking: Noisy connections can be difficult to debug. Use the traffic blocking feature to temporarily pause live traffic. While traffic is paused, you can still simulate custom messages. ✓ Dark Mode Support: Socket Inspector automatically matches your Chrome DevTools theme, including dark mode. 🌐 View the source code or make a support request on GitHub: https://github.com/Socket-Inspector/Socket-Inspector
