Scan your local network

Ready to scan your network

Enter your network, or let LanScan find your gateway, then start the scan. Everything runs inside this browser tab.

CIDR (10.0.0.0/24), a range (10.0.0.1-50 or 10.0.0.1-10.0.1.50), or a single address.

Fast scanning

  • Concurrent probing, calibrated to your network
  • Finds your gateway for you
  • CIDR, ranges and single hosts; your own port list

Results you can keep

  • Devices appear as they are found, open ports as badges
  • What changed since the previous scan of the same network
  • CSV and JSON export, per scan or all at once

Privacy first

  • 100% client-side: nothing leaves your browser
  • No servers, no third-party requests, no tracking
  • Results stay in this browser until you clear them

Works anywhere

  • Installable; works without internet access
  • Phone-friendly layout, keyboard operable
  • Light and dark themes
Comma-separated ports or ranges. Ports a browser refuses to connect to (SSH, FTP, mail, DNS, NetBIOS and others) are skipped and listed when you scan.
