WebSocket Tester
Connect to any WebSocket endpoint, watch the message stream live, and send text or raw hex frames. The connection is opened directly from your browser — nothing passes through our servers.
Browsers block insecure ws:// connections from an HTTPS page. Outside localhost you must use wss://.

Frequently asked questions
Why can I only use wss:// on this page?
Browsers refuse insecure ws:// connections from a page served over HTTPS. Outside localhost you must use the secure wss:// scheme.
Can I send binary data?
Yes. Switch the message input to Hex mode and type pairs of hexadecimal digits, for example 48656c6c6f, to send raw binary frames.
Is anything stored on your servers?
No. The connection is opened directly from your browser and the log lives only in this page — nothing is uploaded.
