Fing Desktop requires a free account and signs in to Fing’s cloud services for device recognition and to sync network data. If that is the reason you are looking, Angry IP Scanner, NETworkManager and Nmap are free, local and account-free — but none of them names consumer hardware as well as Fing does.

You like what Fing shows you, and you are not comfortable with the account — or you work on a network where an account is simply not allowed.
Almost everyone who searches for a Fing alternative is searching for the same thing, and it is not features. It is the account. Fing’s own help centre says the desktop app requires a free Fing account and signs in to Fing’s cloud services for device recognition and to sync your network data, and for a lot of people — contractors, anyone on a client network, anyone whose employer has a data-residency policy — that sentence ends the evaluation.
The honest complication is that the account is not incidental to the product. It is the product. Fing identifies consumer devices better than a purely local tool because it matches what it sees against a database it maintains centrally and improves across its whole user base. Take the cloud away and you have not made Fing private, you have made a different and less capable application.
So this page will not pretend there is a drop-in replacement that keeps Fing’s recognition and drops its account. There is not. What exists is a set of local tools that are honest about what they know, and they are compared below.

Angry IP ScannerThe Angry IP Scanner project
Windows, macOS and Linux. The current release bundles a Java runtime with the Windows and macOS builds; the Linux packages declare a Java dependency instead.
Free and open source.
No account is described in the project’s own documentation.
Scanning and results stay on the machine that ran them. The project added an optional anonymous error-report setting in Preferences in 3.8.1.
The most portable of the free scanners: one tool, three operating systems, no installation required, and an export format for nearly anything you want to do with the list afterwards.
Windows. The project publishes x64 MSI setup and portable builds. The pages we cite do not state a minimum Windows version.
Free and open source under the GNU General Public License v3.
None. The project describes itself as open source, free and without ads, with no subscriptions and no selling of user data; third-party integrations are optional.
Everything runs locally. The project describes optional third-party integrations that the user enables or disables.
It is a toolbox rather than a scanner: IP scanner, port scanner, WiFi analyzer, ping monitor, traceroute, DNS lookup and LLDP/CDP capture sit beside RDP, SSH/PuTTY, PowerShell and VNC clients in one window.
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.
Windows 11, 10, 8 and 7, per the vendor. No macOS or Linux build is published.
Free.
Not stated on the page we cite.
Not stated on the page we cite.
It asks the least of you of anything on a Windows network: no install decisions, a familiar list, and shared-folder and Radmin actions built into the same window.
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.
Angry IP Scanner
You want one free, open-source scanner that behaves the same on Windows, macOS and Linux, and you are comfortable with a Java application.
NETworkManager
You administer Windows networks and you would rather have one open-source window containing the scan, the lookup and the remote session than three separate tools.
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.
Advanced IP Scanner
Every machine you administer runs Windows, you want a free tool that a colleague will already recognise, and you do not need it on a Mac.
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.
What you actually give up
A local scanner sees MAC address prefixes, open ports, hostnames, responses to a handful of protocols, and timing. From that it can often tell you a device is an Apple product, a printer or a router. What it usually cannot tell you is the model number, and modern phones make even the vendor guess unreliable because they randomise their MAC addresses by default.
Fing closes that gap with scale. Any local-only tool that claims to close it the same way is either using a bundled database that ages, or overstating what it knows. We would rather tell you that than sell you a certainty we do not have.
What a local tool can do instead
It can show its reasoning. The approach IPScanner.Pro takes is to display the evidence behind an identification — which probes answered, what the MAC prefix suggests, which ports are open — so that a wrong guess is visibly a guess rather than an authoritative-looking label. On an unfamiliar network that is frequently more useful than a confident answer, because you can tell which rows to distrust.
It can also keep a history. Scans are retained encrypted on the machine that ran them, and a later scan of the same scope is compared against the earlier one to mark what is NEW, GONE or CHANGED. Knowing that a device appeared last Tuesday is a different kind of identification, and it is one that needs no central database at all.
Both of those are shipped. What is not shipped is any cloud feature of our own: online sync of results is designed as an opt-in on top of local storage, and it is not built. There are no accounts and no upload path in the product today.
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.
Angry IP Scanner — The Angry IP Scanner project
It is a Java application. The current release requires Java 21 or newer and bundles a runtime with the Windows and macOS builds, so the download is larger than a native binary.
Plugins load into the running application. The project added a plugin trust confirmation dialog in 3.10.0 for exactly that reason.
The project website’s news page stops in 2019, which makes the project look dormant. The release history says otherwise — 3.10.0 shipped with a bundled runtime, modern Java support and security fixes. Judge the repository, not the news page.
Device identification is deliberately thin. It tells you what answered, not what the thing is.
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.
It has no macOS or Linux version. The vendor’s download page lists Windows only, so “Advanced IP Scanner for Mac” has nothing official to install, and a Mac download offered by some other site would not be the vendor’s.
The vendor’s page does not state how results are stored or whether anything is sent anywhere, so this comparison does not claim either way.
It is closed source, so its behaviour cannot be audited the way an open-source scanner’s can.
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.

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.

Questions people ask
Does Fing Desktop require an account?
Yes. Fing’s help centre states that the desktop app requires a free Fing account and signs in to Fing’s cloud services for device recognition and to sync your network data.
Is there a Fing alternative with no account and no cloud?
Angry IP Scanner, NETworkManager and Nmap are all free, local and account-free. NETworkManager describes itself as open source, free and without ads, with no subscriptions and no selling of user data. IPScanner.Pro’s current desktop workflow is Local Only with no upload path — though it has no public download yet, so it is not an option you can act on today.
Will an account-free scanner identify my devices as well as Fing?
Generally no, and you should be suspicious of any page that says otherwise. Fing’s recognition comes from a central database, and a local tool has only what it can observe. A good local tool compensates by showing you the evidence behind each guess rather than presenting every guess as a fact.
Can I use Fing on a client network?
That is a question for whoever owns the network, not for us. The fact you need in order to ask it properly is the one above: the desktop app signs in to Fing’s cloud services and syncs network data. Bring that sentence to the conversation rather than a general impression.
