📡 Real-time connection

Connect to any WebSocket endpoint — ws:// or wss:// — and maintain a live persistent connection for as long as you need.

📨 Send & receive

Send text messages, JSON payloads, or ping frames and see responses appear in the live message log instantly.

📋 Message history

Every sent and received message is logged with a timestamp and direction indicator so you can trace the full conversation.

Quick messages

One-click presets for common messages like ping, hello, and JSON event payloads — no typing needed for quick tests.

🔒 Secure & private

Connections go directly from your browser to your server. No proxy, no middleman, no logging of your messages.

🌐 ws:// & wss://

Test both secure (wss://) and non-secure (ws://) WebSocket connections. Switch protocols with a single click.
