 ## Features
 
 - ⚡ **Native & fast** — a single self-contained binary; the HTTP engine runs in Go, not a bundled browser runtime.
 - 🗂️ **Tabbed requests** — work on multiple requests side by side.
+- 🔌 **WebSocket & gRPC** — open live WebSocket streams or invoke gRPC methods (via server reflection); connections and output persist alongside your saved requests.
 - 🧩 **Header editor** — manage request headers as simple key/value pairs.
 - 📥 **Import from cURL** — paste a `curl` command and it's parsed, populated, and run instantly.
 - 🎨 **Syntax-highlighted responses** — pretty-printed JSON bodies and response headers.
