Check the traffic stats of netcat on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of netcat on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of netcat's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of netcat on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

Guess streams was a mixed analog / digital world thing[0]. Is 'curl' the higher order wave crest of LC_NETWORK (aka 'sane' http protocol reference to type bundled 0,1,2 file descriptors) One can have curl as a bash loadable routine without the need to recompile bash. Headless or not, much more sane[4] than ctypes.sh[1] as epilog/prolog handled withing context of curl module/program. More relevant logic level... - Source: Hacker News / about 2 months ago
If you don't like using telnet, that's fine. Don't use it. There are plenty of other options available. Use netcat. Or use netcat. Or use netcat. Or read and write directly to /dev/tcp/hostname/port using shell constructs. Or run openssl s_client if you suspect something complicated is listening on the other end. There is more than one way to do it and ways that are not your way still work. Source: about 3 years ago
Reminder, there are many different netcats, here are some of the most commons: - netcat-traditional http://www.stearns.org/nc/ - netcat-openbsd : https://github.com/openbsd/src/blob/master/usr.bin/nc/netcat.c (also packaged in Debian) - ncat https://nmap.org/ncat/ - netcat GNU: https://netcat.sourceforge.net/ (quite rare) To prevent any confusion, I like to recommend socat: http://www.dest-unreach.org/socat/. - Source: Hacker News / almost 4 years ago
A common tool to execute a reverse shell is called netcat. If you're using macOS, it should be installed by default. You can check by running nc -help in a terminal window. - Source: dev.to / about 4 years ago

The original one is the "TCP/IP Swiss army knife" released in 1995: https://nc110.sourceforge.io/ (original release: https://seclists.org/bugtraq/1995/Oct/28) Although it is "freely given away to the Internet community" with "an obligation to give credit where due", at least OpenBSD and GNU have seen the need to write their own versions under their project licenses: GNU netcat: http://netcat.sourceforge.net/... - Source: Hacker News / over 5 years ago

Netcat, often referred to as the "TCP/IP Swiss army knife," has established itself as a versatile and powerful networking utility since its introduction in 1995. Despite the wide array of available networking tools and its own age, netcat remains a popular choice among network professionals for various tasks ranging from simple data transfers to more complex functions like reverse shell execution. This article examines the public opinion surrounding netcat, based on recent discussions and articles.
While netcat remains highly regarded for its simplicity and effectiveness, it is also noted for certain limitations, primarily its lack of comprehensive documentation. This is particularly apparent when compared to more modern tools like Angry IP Scanner and Nmap. Users and reviewers often cite this as a significant drawback, necessitating resources like cheat sheets to effectively harness netcatโs capabilities. Additionally, the latest official version of netcat is dated back to 2004. However, several forks and variants, such as ncat from the Nmap suite and a variant by Mike Frysinger, ensure compatibility with modern operating systems and provide additional functionalities.
Netcat is widely appreciated for its cross-platform compatibility, supporting Windows, Linux, and macOS. It is frequently recommended as an alternative to telnet for socket-related tasks, and its ability to handle both TCP and UDP protocols is especially valued among users who engage in lower-level network communications. Its usage for creating reverse shells, a commonplace task in penetration testing and ethical hacking, highlights its continued relevance in cybersecurity.
An aspect often highlighted in forums and technical discussions is the variety of netcat versions available. This can lead to confusion among users, as different distributions may have variations in syntax and features. For instance, the netcat-traditional, netcat-openbsd, and GNU netcat versions have varying capabilities and licensing agreements. Despite these differences, all versions maintain the fundamental telnet-like syntax, though the specifics of command execution can differโleading to a need for clarity among users.
In terms of competition, netcat's main contenders include tools such as socat, Wireshark, tcpdump, and Ettercap, which may offer more intuitive interfaces or specialized functionalities like packet analysis or traffic interception. Nonetheless, netcat's simple command-line interface and versatility in streamlining network-related tasks make it a favored choice for automation scripts and quick network diagnostics.
Overall, public sentiment regarding netcat is largely positive, albeit acknowledging its aging architecture and the complexity introduced by its various forks. It remains a staple tool for network engineers and IT professionals who require a reliable, lightweight utility for ad-hoc network testing and exploration.
