Older versions (and sometimes newer test releases) are available from the Nmap release archive (and really old ones are in dist-old). For the more security-paranoid (smart) users, GPG detached signatures and SHA-1 hashes for each release are available in the sigs directory (verification instructions). Before downloading, be sure to read the relevant sections for your platform from the Nmap Install Guide. The most important changes (features, bugfixes, etc) in each Nmap version are described in the Changelog. Using Nmap is covered in the Reference Guide, and don't forget to read the other available documentation, particularly the official book Nmap Network Scanning!
Nmap users are encouraged to subscribe to the Nmap-hackers mailing list. It is a low volume (7 posts in 2015), moderated list for the most important announcements about Nmap, Insecure.org, and related projects.

Microsoft Windows binaries
Please read the Windows section of the Install Guide for limitations and installation instructions for the Windows version of Nmap. It's provided as an executable self-installer which includes Nmap's dependencies and the Zenmap GUI. We support Nmap on Windows 7 and newer, as well as Windows Server 2008 R2 and newer. We also maintain a guide for users who must run Nmap on earlier Windows releases..
Note: The version of Npcap included in our installers may not always be the latest version. If you experience problems or just want the latest and greatest version, download and install the latest Npcap release.
Latest stable release self-installer: nmap-7.94-setup.exe
Latest Npcap release self-installer: npcap-1.78.exe
Linux RPM Source and Binaries
Many popular Linux distributions (Redhat, Mandrake, Suse, etc) use the RPM package management system for quick and easy binary package installation. We have written a detailed guide to installing our RPM packages, though these simple commands usually do the trick:
rpm -vhU https://nmap.org/dist/nmap-7.94-1.x86_64.rpm rpm -vhU https://nmap.org/dist/zenmap-7.94-1.noarch.rpm rpm -vhU https://nmap.org/dist/ncat-7.94-1.x86_64.rpm rpm -vhU https://nmap.org/dist/nping-0.7.94-1.x86_64.rpmYou can also download and install the RPMs yourself:
Latest stable release:
x86-64 (64-bit Linux) Nmap RPM: nmap-7.94-1.x86_64.rpm
x86-64 (64-bit Linux) Ncat RPM: ncat-7.94-1.x86_64.rpm
x86-64 (64-bit Linux) Nping RPM: nping-0.7.94-1.x86_64.rpm
Optional Zenmap GUI (all platforms): zenmap-7.94-1.noarch.rpm
Source RPM (includes Nmap, Zenmap, Ncat, and Nping): nmap-7.94-1.src.rpm
Mac OS X Binaries
Nmap binaries for Apple macOS (x86-64) are distributed as a disk image file
containing an installer. The installer allows installing Nmap, Zenmap,
Ncat, and Ndiff. The programs have been tested on
Mac OS X 10.9 and later.
See the Mac OS X Nmap install page for more details.
Users of PowerPC (PPC) Mac machines, which Apple ceased selling in 2006, should see this page instead for support information.
Latest stable release installer: nmap-7.94.dmg
Source Code Distribution
This is the traditional compile-it-yourself format. The Nmap tarball compiles under Linux, Mac OS X, Windows, and many UNIX platforms (Solaris, Free/Net/OpenBSD, etc.) It includes Zenmap, the GUI frontend.
Detailed Linux/BSD/Solaris compilation instructions and options are provided here, though this usually does the trick:
bzip2 -cd nmap-7.94.tar.bz2 | tar xvf - cd nmap-7.94 ./configure make su root make install
Other Operating Systems
Many other operating systems support Nmap so well that I have no need
to create and distribute binary packages myself. You can choose to
use the packages below, or compile the source
distribution, which is often newer. We have created installation pages for the following platforms:
Linux (all distributions)
Mac OS X
FreeBSD, OpenBSD, and NetBSD
Amiga, HP-UX, and Other Platforms
