  • ·10s sandbox timeout · zero CORS pain

HTTP client

  • ·OpenAPI 3.x · cURL import
  • ·Copy as fetch / axios / Python

Realtime (WS + SSE)

↗

Stream-protocol tester — what Postman doesn’t do well.

WebSocket + Server-Sent Events with custom auth headers, auto-reconnect, JSON pretty-print.

  • ·wss:// + ws:// + subprotocols
  • ·SSE via fetch — Authorization works
  • ·Auto-reconnect with backoff
  • ·Send composer · ⌘ + Enter

What it does

A regex tester runs your pattern against sample text and highlights what matches. Beyond that, our tester checks whether your pattern uses constructs that other language flavors (Java, Python, Go) don’t support — and generates ready-to-paste code for each.
