100% private — your device list never leaves your browser
Who's On My WiFi
Find your devices
Get your device list first:
- Windows: open Command Prompt, type
arp -a, copy the output. - Mac: open Terminal, type
arp -a. - Linux: open a terminal, type
ip neigh. - Or copy the connected-devices table straight from your router's admin page — see the tab. Either format pastes into the same box below.
Devices found
Paste your ARP table or router device list on the left. The device table — IP, MAC, vendor, and a device-type guess — lands on this sheet.
Why can't a website just scan my router?
Two browser protections stop it on purpose. The Same-Origin Policy stops any page from reading a response from a different origin — your router's admin panel never sends the "Access-Control-Allow-Origin" header that would permit it. And since 2024, Chrome's Local Network Access rules go further: a public HTTPS page reaching a private IP like 192.168.1.1 at all — even a plain image request — now needs an explicit permission prompt, the same defence that stops a malicious page from silently reconfiguring your router (a real attack class called router CSRF). Any "WiFi scanner" website that skips this either fakes its results or asks for your router password — a real credential-theft risk. Native apps like Fing work because they run as an installed app with real OS-level network permissions, not inside a browser tab.
3 ways to actually check your connected devices
- Run arp -a (fastest, no login needed). Windows: Command Prompt →
arp -a. Mac: Terminal →arp -a. Linux:ip neigh. This shows every device your computer has recently talked to on the same WiFi — no router password required. - Open your router's admin page. JioFiber (192.168.29.1), Airtel Xstream (192.168.1.1), ACT Fibernet, TP-Link, Netgear, ASUS, and D-Link all have a connected-devices page — see the brand-by-brand guide in the Open Router Admin tab above.
- Paste either one into this tool. It parses the text entirely in your browser and looks up each device's manufacturer from its MAC address — nothing leaves this tab.
Identifying an unknown device by its MAC vendor
Every network device's MAC address starts with a 6-character manufacturer code (the OUI) assigned by the IEEE — 20:15:82 is Apple, DC:A6:32 is Raspberry Pi, and so on. This tool looks that prefix up against a curated table of ~2,000 real IEEE-registered vendors, entirely offline. Two honest caveats: modern phones (iOS 14+, Android 10+) use a randomized "Private WiFi Address" that changes per network, so the vendor lookup can miss or mislead on those — this tool flags them as private; and a vendor match tells you who made the chip, not who owns the device, so treat it as a strong hint, not proof.
Found a device you don't recognise? Blocking it
- Copy the unknown device's MAC address from the table above.
- Open your router's admin page (Open Router Admin tab) and find its MAC filtering / block-device option — every major router (JioFiber, Airtel Xstream, TP-Link, Netgear) has one.
- If several devices look unfamiliar, the faster fix is changing your WiFi password from the same admin page — it disconnects everyone, and only people with the new password reconnect.
Why this tool, not the sites that claim "real-time scan"
Search "who is on my wifi" and most results either fake it — a canned or randomized device list with no real detection — or ask for your router admin password to "log in for you", a genuine credential-theft risk. Toolsda never asks for a password, never claims to scan your router directly, and never uploads what you paste — the parsing, the vendor lookup, and the device-type guess all run in this browser tab.

Frequently Asked Questions
How do I check who is connected to my WiFi?
Run arp -a in Command Prompt (Windows) or Terminal (Mac), or ip neigh on Linux, then paste the output into this tool — it lists every device with its IP, MAC address, and likely manufacturer, entirely in your browser. You can also copy the connected-devices table straight from your router's own admin page.
Can a website scan my router or WiFi network directly?
No, and any site claiming to is either lying or asking for your router password (a real risk). Browsers block cross-origin requests to your router (CORS) and, on current Chrome, even a plain page load to a private IP now needs an explicit Local Network Access permission. This tool is a parser, not a scanner: it reads the device list you paste, on-device, and never touches your router.
How do I see connected devices on JioFiber?
Open 192.168.29.1 in a browser (or the MyJio app → WiFi Settings), log in with the admin credentials printed on the router's label, then open Status → Connected Devices. Paste that list here for vendor lookup and a device-type guess.
What is an ARP table?
ARP (Address Resolution Protocol) is how your computer maps IP addresses to MAC addresses on your local network. Running arp -a shows every device your computer has recently talked to on the same WiFi — which is effectively the device list, without needing router access at all.
How do I block an unknown device from my WiFi?
Log into your router's admin panel (see the brand guide in the Open Router Admin tab), find the device by its MAC address, and use its block/deny or MAC-filter option — every major router (JioFiber, Airtel Xstream, TP-Link, Netgear) has one. If you don't recognise several devices, the safer fix is usually just changing your WiFi password.
This tool parses data you provide — it does not access your router. For continuous real-time monitoring, use your router's own admin panel or a native app like Fing. Vendor data is sourced from the IEEE OUI registry and, like any manufacturer database, can be incomplete or outdated for very new hardware.
