Connect to any WebSocket endpoint from your browser. Send messages and inspect the full frame log with timestamps.
The WebSocket protocol (RFC 6455) provides full-duplex communication channels over a single TCP connection. Unlike HTTP, a WebSocket connection stays open, allowing both the client and server to push data at any time. This tool uses the browser’s native WebSocket API - no proxy or backend required.
Useful for testing WebSocket APIs, debugging real-time applications, verifying message formats, and exploring chat or streaming endpoints. The JSON tag highlights frames that contain valid JSON payloads. Note: browsers block non-secure ws:// connections when the page is loaded over HTTPS. Use wss:// endpoints for browser-based testing.
