CORS Proxy Setup
For WebSocket connections through a proxy, run Holy CORS locally:
# macOS (Homebrew)
brew install bugdays-com/tap/holy-cors
holy-cors
# Docker
docker run -p 2345:2345 ghcr.io/bugdays-com/holy-cors
Note: Most WebSocket servers support cross-origin connections natively. Only use the proxy if you encounter connection issues.
Free Online WebSocket Tester
Test WebSocket connections in real-time. Connect to WS or WSS endpoints, send text or JSON messages, and view incoming messages with timestamps. Perfect for debugging WebSocket APIs and real-time applications.
