Smap
a drop-in replacement for Nmap powered by shodan.io
Smap is a passive port scanner designed as a drop-in alternative to Nmap while using Shodan.io data. It accepts many familiar Nmap-style command-line arguments and can produce Nmap-like output formats, which makes it easier to integrate into existing workflows. Because it relies on Shodan’s free API, it can scan quickly without directly contacting targets in its default mode. The project emphasizes speed, with support for scanning large numbers of hosts per second. Smap can provide service and version fingerprinting, vulnerability detection, and results in formats such as XML, greppable, normal, JSON, and custom output. It is useful for authorized reconnaissance where fast external visibility matters, while users should remember that passive results may be delayed or incomplete compared with active scanning. -

masscan
Mass IP port scanner
Masscan is an Internet-scale port scanner, able to scan the entire Internet in just 6 minutes or less. It's considered the fastest port scanner and is similar to the famous port scanner nmap, and like port scanners scanrand and unicornscan it uses asynchronous transmissions. However, it is more flexible when it comes to arbitrary port and address ranges. Masscan not only detects when ports are open, it can also check banners. And while it is useful for smaller, internal networks, it's designed with the entire internet in mind. Do take note however that Masscan uses its own custom TCP/IP stack, so anything other than a simple port scan could cause conflict with the local TCP/IP stack unless certain configurations are done. -

xpoc
A fast emergency response tool designed for supply chain vulnerability
xpoc is a lightweight command-line scanner created for fast emergency response in supply chain vulnerability scanning. It is designed to help security teams test single targets, multiple targets, and target lists through direct input, files, or pipes. The tool can retrieve proof-of-concept plugins from the cloud, list available plugins, synchronize new plugins, and update itself from the command line. It uses the xray YAML POC format and supports plugin writing and loading for TCP and UDP checks. It can also be extended with custom Go plugins for more advanced detection logic, crawling, screenshots, and additional scanner behavior. It is most useful for authorized vulnerability validation, rapid triage, and security teams that already work with the xray ecosystem. -

RustScan
The Modern Port Scanner
The Modern Port Scanner. Find ports quickly (3 seconds at its fastest). Run scripts through our scripting engine (Python, Lua, Shell supported). Scans all 65k ports in 3 seconds. Full scripting engine support. Automatically pipe results into Nmap, or use our scripts (or write your own) to do whatever you want. Adaptive learning. RustScan improves the more you use it. No bloated machine learning here, just basic maths. The usuals you would expect. IPv6, CIDR, file input and more. Automatically pipes ports into Nmap. RustScan is a modern take on the port scanner. Sleek & fast. All while providing extensive extendability to you. Not to mention RustScan uses Adaptive Learning to improve itself over time, making it the best port scanner for you. Speed is guaranteed via RustScan. However, if you want to run a slow scan due to stealth that is possible too. We have tests that check to see if RustScan is significantly slower than the previous version. -

ZMap
ZMap is a fast single packet network scanner for network surveys
ZMap is a fast single packet network scanner designed for Internet-wide network surveys. On a typical desktop computer with a gigabit Ethernet connection, ZMap is capable scanning the entire public IPv4 address space in under 45 minutes. With a 10gigE connection and PF_RING, ZMap can scan the IPv4 address space in under 5 minutes. ZMap operates on GNU/Linux, Mac OS, and BSD. ZMap currently has fully implemented probe modules for TCP SYN scans, ICMP, DNS queries, UPnP, BACNET, and can send a large number of UDP probes. If you are looking to do more involved scans, e.g., banner grab or TLS handshake, take a look at ZGrab 2, ZMap's sister project that performs stateful application-layer handshakes. ZDNS is a utility for performing fast DNS lookups, such as completing an A lookup for all names in a zone file, or collecting CAA records for a large number of websites. ZDNS contains its own recursive resolver and supports A, AAAA, ANY, AXFR, CAA, CNAME, DMARC, MX, NS, PTR, TXT, etc. -

scanless
Online port scan scraper
scanless is a Python command-line utility and library for running port scans through third-party online scanning services. It is built for users who want quick visibility into exposed ports without running a local scanner directly from their own machine. The tool can scan an IP address or domain, choose a specific supported scanner, select a random scanner, or run all available scanners. It supports services such as ipfingerprints, spiderip, standingtech, viewdns, and yougetsignal. scanless can return raw scan output as well as parsed results that include port, state, service, and protocol details. The repository is archived and no longer maintained, so it is best treated as a legacy utility for authorized testing, research, or reference use. -
