Browser Compatibility
This page is designed for browsers that can open secure WebSocket connections and expose at least some local-network hints through WebRTC.
WSS Scan
Secure local WebSocket scanning.
This page targets wss scan, websocket scanner, and related secure local endpoint checks. It probes likely local IPs with browser-based wss:// requests instead of older insecure scan patterns.
It is also the replacement for the old /websocket.php page and keeps the secure local endpoint focus of the original tool.
The WSS scan runs from your browser on your device. No server-side network scan is performed against your local subnet from router.fyi infrastructure.

How this scan works
Collect local subnet hints with WebRTC when available.
Generate a focused list of likely gateways and common secure local endpoints.
Test those candidates with
wss:// requests and show whether each endpoint opened, errored, or timed out.Local IP hints
No local address hints yet.

FAQ
What does “error” mean in the WSS result list?
An error often means the IP responded in some way but did not complete a successful WebSocket handshake. That can still be a useful reachability signal.
Why not scan every address from 1 to 254?
This rewritten page stays compact and browser-friendly. It focuses on likely router and local service endpoints instead of treating every visit as a full subnet sweep.
