Nmap with Zenmap is a security auditing tool: scripting, service and version detection, deep output. IPScanner.Pro is an inventory tool: retained encrypted history, changes since the last scan, and visible evidence behind each identification. Nmap is free and available now; IPScanner.Pro has no public download.

You are trying to work out whether these are competing tools or complementary ones. Mostly they are complementary.
The most useful thing this page can do is tell you these are not really alternatives to each other, and that anyone presenting them as a straight fight is selling something.
Nmap is a security auditing tool. Service and version detection, OS fingerprinting, and the scripting engine are its purpose, and Zenmap — the project’s own graphical front end, included in the Windows and macOS installers — makes those approachable without changing what they are. When the question is "what exactly is listening on that port, and is it what it claims to be?", nothing else on this site answers it.
IPScanner.Pro is an inventory tool. Its questions are "what is here, what was here last time, and what changed?" Those need retained history and a record you can trust, not deeper probing. If you do both kinds of work, you will end up wanting both kinds of tool.
Side by side
Every cell about a product we do not make is what that vendor or project publishes about itself. “Not stated in the source we cite” means exactly that — the source does not cover the point, so it is left blank rather than filled in from memory.
Competitor entries come from the sources in the citation table below, each retrieved on the date shown there. Our own row states shipped capabilities only.

Nmap with ZenmapThe Nmap Project
Windows 7 and newer, macOS (the official installer is published for x86-64 and tested on macOS 10.9 and later), Linux packages, and source for other systems.
Free, under custom licence terms derived from the GNU GPL.
Not stated on the page we cite.
Scanning and output stay on the machine that ran them.
Nothing else on this page is in the same class for depth. Service and version detection, OS fingerprinting, and a scripting engine make it the tool you graduate to when “which hosts are up” stops being the question.
A native macOS application. A Windows x64 portable build is implemented, but native acceptance testing is not complete.
Free-first for individuals. Paid organisation features are planned, not available.
No account for local scanning. The current desktop workflow is Local Only; optional online sync is designed but not built.
On the machine that scanned, encrypted, keyed to the macOS Keychain or Windows DPAPI. Online sync is designed as a per-device opt-in on top of that, and it does not exist yet — there is no upload path in the product today.
It shows the evidence behind every identification instead of asserting an answer, keeps encrypted history so you can see what changed since last time, and prices an expensive action before it runs rather than after.
Our own product, not a citation.
Which one to pick
A comparison that steers every reader to the same answer is an advertisement. These are the conditions under which each tool here is the right choice — including the ones that are not ours.
Nmap with Zenmap
You need scripting, service and version detection, or auditable output you can diff — and you are willing to learn the options rather than click a button.
IPScanner.Pro
You want to know why a device was identified the way it was, and you want the result to stay on your machine unless you deliberately decide otherwise.
Where Nmap is simply better
Depth, documentation and reach. It is distributed for Windows 7 and newer, macOS, Linux packages and source, under custom licence terms derived from the GNU GPL. Its behaviour is documented more thoroughly than anything else in this category, its output is machine-readable and diffable, and its scripting engine means the tool grows to fit questions its authors never anticipated.
It is also free and available everywhere right now, which IPScanner.Pro is not. One practical caveat: the official macOS installer is published for x86-64 and tested on macOS 10.9 and later, so Apple-silicon Macs mean translation or a source build.
Where an inventory tool fits instead
Nmap will tell you the truth about a host at the moment you ask. It will not tell you that the host appeared on Tuesday, that its open ports changed since the last sweep, or that the device you remember from last month has stopped answering — not without you building that layer yourself out of saved output and diffs. Plenty of people do build it, and it is real work.
That layer is what IPScanner.Pro is: encrypted retained scans on the machine that ran them, NEW, GONE and CHANGED computed against earlier evidence for the same scope, matched first-seen dates preserved, and partial scans suppressed from emitting GONE so an interrupted run cannot invent a disappearance. Full ports exists for when you want depth on specific devices — but it is a selected-device action on a finished discovery, priced before it runs, not a scripting engine.
And the ceiling is real: no public download, macOS verified with Windows acceptance incomplete, no service-version detection, no scripting, no OS fingerprinting. If you need those, you need Nmap, and this page is not going to pretend a selected-device port scan is a substitute.
What each of these cannot do
Every entry below includes the tool we make, on the same terms and in the same list. The competitor entries state capabilities, not quality judgements.
Nmap with Zenmap — The Nmap Project
It is built for operators. The primary interface is a command line and the output is text; Zenmap is a front end, not a substitute for learning the flags.
The official macOS package is published for x86-64, so an Apple-silicon Mac means relying on translation or building from source as the project documents.
It is a general-purpose auditing tool, so it does not attempt the “what is this device, and why do we think so?” presentation the other entries here aim for.
Its defaults are powerful enough to alarm an IDS or upset a fragile device. That is a feature for an auditor and a hazard for someone who just wanted a device list.
There is no public download. Signed and notarized distribution does not exist yet, so nothing on this site offers an installer or a version number.
macOS is the verified platform. The Windows x64 build is implemented but has not completed native acceptance testing.
Full ports is not a whole-range sweep. It runs only on devices you select from a completed discovery in the same session.
Restored inventory is labelled historical and never claims a device is reachable now. Startup restore covers the newest retained scan and stops at 256 devices; the History dialog covers the rest.
Device identification can be incomplete. Private MAC addresses, blocked responses and thin evidence limit what any local tool can conclude.
Online sync, accounts and organisation features are not built. The design keeps local storage as the default and adds sync as an opt-in, but none of it ships today.
Scanning on macOS requires Local Network permission; Windows may show a firewall prompt or apply an organisation policy.
What we have built, and what we have not
The row above is a summary. This is the full list, marked by whether it exists today. A feature marked planned is a design decision, not a promise with a date, and nothing on this site should be bought or downloaded on the strength of one — there is nothing to buy or download yet.
ShippedBounded discovery with visible evidence. Quick, Balanced and Thorough discovery inside a scope you authorize, showing provisional rows while the scan runs and the evidence behind every identification.
ShippedFull ports on devices you select. A selected-device action on a finished discovery in the same session, priced as devices × 65,535 attempts before you confirm. It is not a whole-range sweep.
ShippedEncrypted local history. Scans are retained encrypted on the machine that ran them, keyed to the macOS Keychain or Windows DPAPI, with a one-year default retention you can change.
ShippedNEW, GONE and CHANGED against earlier scans. Manual records compare against earlier evidence for the same scope, preserve matched first-seen dates, and suppress GONE on a partial scan so an interrupted run cannot invent a disappearance.
ShippedLocal Only as the default data path. The current desktop workflow is Local Only: results are written to the machine that scanned and there is no upload path in the product today.
PlannedOptional online sync of results. The design keeps local storage as the default and adds sync as a per-device opt-in, so a result reaches a server only when you turn it on. It is not built: there are no accounts, no registered agents and no durable storage yet, and nothing on this site should be read as offering it today.
PlannedSigned, public downloads. There is no public download. Signed and notarized distribution does not exist yet, which is why no page on this site carries a download button or a version number.
Every claim, and where it came from
Every statement about another product on this page comes from that vendor’s or project’s own published material, with the retrieval date shown for each source. Where a source does not cover a point, the table says so instead of guessing. This page contains no benchmarks, no speed or accuracy comparisons and no hands-on measurements of the other tools: we did not test them to write it.
Each row is a claim this page makes about a product we do not make, and the publication it came from.

About this page and who wrote it
This page was written from the vendors’ and projects’ own published documentation and from the IPScanner.Pro codebase, including the scope, consent and Full-ports rules the desktop application enforces. It makes no first-hand claim about how any other tool behaves in practice, because we did not test them to write it.
Where it is wrong, or where a cited product has changed, support@ipscanner.pro reaches the person who maintains it, and corrections are made rather than argued with. A suspected security issue in IPScanner.Pro goes to security@ipscanner.pro instead — there is a disclosure policy setting out what happens next.

What this page is based on
The vendors’ and projects’ own published documentation, and the IPScanner.Pro codebase. No benchmark, and no hands-on test of any other tool listed here.
Questions people ask
Can IPScanner.Pro replace Nmap?
No. It does no service and version detection, no OS fingerprinting and no scripting. If your work needs any of those, Nmap is the tool, and there is no version of this comparison where that changes.
Is Zenmap still the official Nmap GUI?
Yes — Zenmap is the Nmap Project’s official graphical front end and is included in the Windows and macOS installers.
Why would I use both?
Because they answer different questions. Discovery and inventory on a schedule, with a record of what changed, is one job; establishing exactly what a specific service is running is another. Using Nmap for the second does not make the first go away.
Is Full ports the same as an Nmap port scan?
Not really. Full ports runs against devices you select from a finished discovery in the same session, and it prices the run as devices × 65,535 attempts before you confirm. It has no scripting, no version detection and no timing templates. It is a deliberate, bounded action rather than a scanning language.
