About This Tool
The WebSocket Latency Tester measures the round-trip time (RTT) of a WebSocket connection by sending a timestamped ping message and calculating how long it takes for the response to come back — useful for diagnosing network performance issues in real-time applications.
Connect to an echo-style endpoint, then send a manual ping or enable automatic 1-second pinging to watch latency update live. Since it relies on the server echoing the ping payload back, it's best used against an endpoint designed for this — like the default wss://echo.websocket.in — rather than an arbitrary production WebSocket server.
How to Use This Tool
Enter your WebSocket URL
Point it at an echo-style endpoint that reflects messages back to the sender.
Click "Connect"
A ping is sent automatically as soon as the connection opens.
Send a ping or enable auto-ping
Trigger a manual ping, or let it ping automatically once per second.
Read the latency result
See the round-trip time in milliseconds, updated after every pong.
Common Use Cases
Testing Real-Time App Performance: Check round-trip time for a chat, gaming, or trading system before shipping.
Detecting High-Latency Connections: Spot a slow or degraded WebSocket endpoint during development.
Monitoring Server Response Times: Keep an eye on how quickly your server responds under normal conditions.
Validating Network Stability: Run auto-ping over time to see how consistent latency is on a given connection.
Why Use This Tool
Precise Round-Trip Timing
Uses high-resolution timestamps to measure latency down to fractions of a millisecond.
Manual or Automatic Pings
Send a single ping on demand, or enable continuous 1-second auto-ping.
