WiFi & Network Scanner: NetOS

Coderilla

About this app

See every device on your WiFi, scan its ports, and run real network commands from a built-in terminal.

NetOS is a network scanner, port scanner, Bluetooth scanner and REST client in one retro, green-on-black console. No account, no ads, no tracking. Your scans never leave your device.

NEW: A REAL COMMAND LINE
Almost everything you can tap in NetOS, you can also type. The CLI tab gives you a shell-style terminal with autocomplete, command history and a searchable cheatsheet.
• Scan your network with net scan, list hosts with net hosts, ping a device, find Bonjour names with mdns
• Run a Bluetooth scan with bt scan, or send an HTTP request with http
• Paste a curl command and run it as is
• Filter output with pipes: | grep, | sort, | head, | copy
• Chain commands with &&, set aliases and variables, run multi-line scripts
• Repeat any command with watch, or run long scans as background jobs
• Split the terminal into up to 4 panes and keep separate sessions

NETWORK SCANNER & IP SCANNER
• Find every device on your WiFi or LAN: IP address, hostname, vendor and device type
• Bonjour / mDNS discovery shows the names devices announce
• Ping any host to check it is alive
• Every scan is saved per network, so new and unknown devices stand out
• Name devices, set their type and add notes: your own network inventory

PORT SCANNER
• Quick port scan of common ports, or a custom range of up to 5,000 ports per run
• Open, closed and silent ports, each with its likely service
• Save your own port lists for a NAS, a dev server, a printer or a camera

WIFI
• Your current WiFi network: SSID, BSSID and security
• A history of every network you have joined, with saved passwords kept on the device

BLUETOOTH LE SCANNER
• Nearby Bluetooth devices in real time, with signal strength
• Identifies manufacturer and type: headphones, watches, beacons, keyboards and more
• Link a Bluetooth device to the LAN host it belongs to

REST API CLIENT
• Send GET, POST and other HTTP requests with headers, query params and JSON or form bodies
• Cookie jar, response history and request collections
• Export any request as cURL
• Targets fill in from the services NetOS discovered on your network

NETWORK MAP
• A live graph of your networks, devices, open ports and Bluetooth links
• A map view of every located network and device
• Switch to a plain list whenever you prefer

PRIVATE BY DESIGN
A network scanner sees a lot, so NetOS keeps all of it on your phone.
• No account, no cloud, no ads, no tracking
• Everything you scan is stored only on your device
• Export and import your data as JSON files you own
• One tap wipes everything

ALSO INCLUDED
• Simulation mode: explore every feature with simulated networks and devices
• Three themes: Phosphor (green on black), Daylight (for sunlight) and Abyss (deep blue)

Who it is for: developers, IT admins, homelab tinkerers, and anyone who wants a network scanner that shows what is really connected to their WiFi. Use NetOS on networks you own or are allowed to test.

Available in English, German, Spanish, French, Italian, Dutch, Portuguese and Bulgarian.
