Browser Compatibility
This page can work in more than one way, but browser policy matters. Some browsers allow more timing-based local discovery than others.
Web-Based IP Scanner
Browser network scanning with cleaner results.
This page is the primary target for search intent like router ip scanner, web based ip scanner, ip scanner browser, and web based network scanner. It wraps the legacy webscan approach in a mobile-friendly UI with clearer results and caveats.
The scan still runs from your browser, not our server. Modern browsers may limit parts of the old technique, so this page uses progressive enhancement and explicit status reporting instead of a raw debug dump.
Browser scans are launched from your device. Router.fyi does not upload your local network inventory. Exact results vary by browser, operating system, and how aggressively the browser limits local-network probing.

How webscan-style scanning works
Try common gateway patterns first to find a live subnet.
Use WebRTC to help detect local IPs when the browser exposes them.
Probe likely local IPs and report responsive devices, probable router IPs, and scan logs in separate sections.

FAQ
Is this the same as Samy Kamkar's webscan?
This page reuses the browser-side webscan engine as a scanning layer, then wraps it in a rewritten UI. Credit belongs to Samy Kamkar's webscan.
Why can the same browser IP scanner behave differently across browsers?
Because the scan relies on local-network timing and browser APIs that are not handled consistently across Safari, Chrome, Firefox, Edge, mobile browsers, and future privacy changes.
Does this scan every IP on my subnet?
Not blindly. The rewritten page prioritizes likely gateways and live subnets, then shows the devices it can detect, instead of dumping a raw page of text output.
