netscanner is a network scanner and diagnostic tool supporting WiFi scanning, packet dumping, port scanning, and traffic counting.
Summary
netscanner is an open-source network scanner and diagnostic tool that runs in the terminal as a text-based interface rather than a GUIGUIA graphical user interface, controls such as windows, buttons and menus. It lets people use software visually rather than entering commands. application, packaged as a command-line tool you install via cargo or your distribution's package manager (it's already in Arch, Alpine edge, and other repos). It requires root privileges to capture packets, and covers host discovery, WiFi network and signal scanning, CIDRCIDRA notation for a block of IP addresses, such as 10.0.0.0/24. The number after the slash says how many leading address bits identify the network. pinging with hostname and MAC resolution, TCPTCPA network protocol that delivers a reliable, ordered stream of bytes between two endpoints. It detects lost data and retransmits it. port scanning, and packet dumping across IPv4, IPv6IPv6The current version of the Internet Protocol, standardized by the IETF, using 128-bit addresses to replace the exhausted IPv4 space. Cyber tools target it because modern networks run dual-stack or IPv6-only., TCP, UDPUDPA network protocol that sends individual messages without guaranteeing delivery or order. Applications trade built-in reliability for less overhead and can add their own recovery., ICMP, and ARP, with CSV export for scanned data. This suits network engineers and security practitioners who want live recon and packet visibility from a single terminal session rather than stitching together separate ping, nmap, and tcpdump invocations. It runs on Linux, macOS, and Windows, the latter needing Npcap installed separately. First committed in 2023, it has 13 contributors and a release 46 days ago, suggesting active maintenance.

How netscanner helps
Which devices are alive on this subnet right now?
pings the whole CIDR range and resolves each responder's hostname and MAC address, tagging the vendor via OUI lookup as results come in
What is actually listening on a given host's TCP ports?
scans the target's TCP ports and reports which are open, building the list live rather than requiring a separate port-scan invocation
Which WiFi networks are visible from here and how strong is each signal?
scans nearby access points and charts signal strength over time so weak or fluctuating connections are visible at a glance
What traffic is actually crossing this interface right now?
dumps packets across TCP, UDP, ICMP, ARP and ICMP6 with start and pause control, and filters the log so a specific conversation can be isolated
Which interface should be capturing this scan?
lists the machine's hardware interfaces and lets the active one be switched without restarting the scan or packet dump
How do I get scanned hosts, ports, and packets into another tool for reporting?
exports the captured IPs, ports, and packet data to CSV in the user's home directory for use outside the terminal session

Nine scores for netscanner, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.
Score cards are part of every paid plan.

Blank means never measured; nothing here is a filled-in zero.
Peer standings are included with Researcher and Business. See how this tool ranks against its competitors, using data we don't publish anywhere else.
See plans →Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.
How this is scored
- Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
- Documentation quality — the release-notes rubric published on the analytics page, unchanged.
- Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
- Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
- Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
- Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
- Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
- Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.
