NetworkSherlock is a powerful and flexible port scanning tool designed for network security professionals and penetration testers. With its advanced capabilities, NetworkSherlock can efficiently scan IP ranges, CIDR blocks, and multiple targets. It stands out with its detailed banner grabbing capabilities across various protocols and integration with Shodan, the world's premier service for scanning and analyzing internet-connected devices. This Shodan integration enables NetworkSherlock to provide enhanced scanning capabilities, giving users deeper insights into network vulnerabilities and potential threats. By combining local port scanning with Shodan's extensive database, NetworkSherlock offers a comprehensive tool for identifying and analyzing network security issues.
NetworkSherlock requires Python 3.6 or later.

Fast and lightweight, UDPX is a single-packet UDP scanner written in Go that supports the discovery of over 45 services with the ability to add custom ones. It is easy to use and portable, and can be run on Linux, Mac OS, and Windows. Unlike internet-wide scanners like zgrab2 and zmap, UDPX is designed for portability and ease of use.
Scanning UDP ports is very different than scanning TCP - you may, or may not get any result back from probing an UDP port as UDP is a connectionless protocol. UDPX implements a single-packet based approach. A protocol-specific packet is sent to the defined service (port) and waits for a response. The limit is set to 500 ms by default and can be changed by -w flag. If the service sends a packet back within this time, it is certain that it is indeed listening on that port and is reported as open.
A typical technique is to send 0 byte UDP packets to each port on the target machine. If we receive an "ICMP Port Unreachable" message, then the port is closed. If an UDP response is received to the probe (unusual), the port is open. If we get no response at all, the state is open or filtered, meaning that the port is either open or packet filters are blocking the communication. This method is not implemented as there is no added value (UDPX tests only for specific protocols).
Concurrency: By default, concurrency is set to 32 connections only (so you don't crash anything). If you have a lot of hosts to scan, you can set it to 128 or 256 connections. Based on your hardware, connection stability, and ulimit (on *nix), you can run 512 or more concurrent connections, but this is not recommended.
To scan a single IP:
udpx -t 1.1.1.1
To scan a CIDR with maximum of 128 connections and timeout of 1000 ms:
udpx -t 1.2.3.4/24 -c 128 -w 1000
To scan targets from file with maximum of 128 connections for only specific service:
udpx -tf targets.txt -c 128 -s ipmi
Target can be:
IPv6 is supported.
If you want to store the results, use flag -o [filename]. Output is in JSONL format, as can be seen bellow:
{"address":"45.33.32.156","hostname":"scanme.nmap.org","port":123,"service":"ntp","response_data":"JAME6QAAAEoAAA56LU9vp+d2ZPwOYIyDxU8jS3GxUvM="}

You can grab prebuilt binaries in the release section. If you want to build UDPX from source, follow these steps:
From git:
git clone https://github.com/nullt3r/udpx
cd udpx
go build ./cmd/udpx
You can find the binary in the current directory.
Or via go:
go install -v github.com/nullt3r/udpx/cmd/udpx@latest
After that, you can find the binary in $HOME/go/bin/udpx. If you want, move binary to /usr/local/bin/ so you can call it directly.
The UDPX supports more then 45 services. The most interesting are:

Please send a feature request with protocol name and port and I will make it happen. Or add it on your own, the file pkg/probes/probes.go contains all available payloads. Specify the protocol name, port and packet data (hex-encoded).
