See every device on your network
Macadress Scanner finds every device on your LAN and identifies its vendor, device type, and virtualization status. Free, running entirely on your own machine.
Download for Linux (.deb)
What one scan finds
- Every device on your local network, discovered by IP, MAC address, and hostname
- Vendor and manufacturer, from the same live-synced OUI database as the API
- Device type and confidence (router, smart TV, phone, embedded device, and more)
- Randomized-MAC and virtualized-host detection
- mDNS/SSDP/NetBIOS hints: the actual product name, when a device advertises one
Runs on your machine, not ours
- Discovery (the ping sweep, ARP, mDNS/SSDP, NetBIOS) never leaves your computer
- No account needed to scan, extract MAC addresses from pasted text, or export results
- Sign in only if you want vendor/device intelligence added to what's already found
- A deeper "advanced scan" pass asks for administrator access explicitly, explains why first, and only for that one pass

Common questions about the app
Does this send my network data anywhere?
Discovery, the ping sweep, ARP, mDNS/SSDP, NetBIOS, everything that actually finds devices, runs entirely on your machine and never leaves it. The only network call is optional: sign in to look up a found MAC's vendor, device type, or virtualization status against macadress.com's database.
Do I need to sign in?
No. Scanning, extracting MAC addresses from pasted text, and exporting results all work without an account. Signing in with a free API key adds vendor names, device categories, and virtualization detection to what a scan already found.
Does it need administrator access?
A normal scan doesn't. Advanced scan, for finding devices that silently drop ping but still answer ARP, asks macOS for administrator access for that one deeper pass, and explains why before it does.
Is it free?
Yes, the app itself always is. Vendor/device lookups draw on the same free tier as the API and web tool (1,000 lookups a month, no card required).
What about Windows and Linux?
Linux is available now: a .deb for Debian/Ubuntu-based distributions, or a raw tarball for anything else. Windows support already works in the scanning code (it just shells out to the OS's own ping/arp) but isn't packaged yet.
