Download cURL Command Line Tool and Library Open Source
cURL is free and open-source that hundreds of contributors and sponsors support. For all portability-related functionality, cURL is driven by libcurl.
cURL is used for the transmission of data in command lines or scripts. It is also used in vehicles, TVs, routers, printers, soundtracks, mobile devices, tablets, set-top boxes, and media players and is a backbone of hundreds of software programs that touch billions of people each day on the internet.
cURL includes a remarkable array of essential features such as proxy support, user authentication, FTP upload, HTTP publishing, SSL connections, cookies, file transfer resumption, Metalink, and more. As you can see below, the number of features will make your head spin!
Durable and reliable!
It was released in its current ‘incarnation’ in 1998 and has been in continuous use by many applications and companies ever since. Sure, there were bugs and even some security flaws, but it remained a very robust and reliable library and many users are still using versions released many years ago as they stick to what works.
Unparalleled set of features!
✔️ There is simply no other library for HTTP and FTP that can boast the same amount and set of features that cURL provides. Whether it’s free or commercial.
✔️ The unique view of both the checkout and push interface allows apps to use them exactly the way they like.
✔️ It also offers an unparalleled set of links, allowing you to access and use cURL from any language you can think of!
It is widely used!
It is the most widely used C-based transport library in the world.
Some of the world’s largest companies use it for high-volume applications.
It is used in some open source applications that are widely used.
The number of its frequent users, intentionally or unintentionally, exceeds one million users.
Many systems and CPUs have ported cURL. Provides the same API and all of them with the same functionality! Ensure that you are able to create your application in a wide variety of applications such as Solaris, NetBSD, FreeBSD, OS/2, BeOs, Mac OS, Ultrix, QNX, OpenVMS, RISC OS, Novell NetWare, DOS, and many more, but not just Solaris, NetBSD, FreeBSD, HPUX, IRIX, AIX, and other systems.
It’s a safe program, but there are a few exceptions. See libcurl-thread (3) for more information.
All protocols function wonderfully on IPv6 packets, along with enabled IPv6 support. Some little things have to be taken into account:
- Kerberos4 does not run on IPv6 by design
- SOCKS4 support is not properly adapted to IPv6.
- There is nothing specifically required to use IPv6.
- The library API remains exactly the same and adapts to IPv4 / IPv6 dynamically.
- Can use only hostnames that have AAAA DNS records,
- Can use only IPv6 IP style addresses.

You can get help with a mailing list, quickly and accurately. Often within a few hours. The availability of mailing list archives on the web makes them searchable and allows you to find solutions and answers previously mentioned.
CURL has a common bug tracker and mostly known bugs are fixed very quickly.
It also provides very detailed documentation about all the processes, not only in each version archive but also available on the website(s).
You can get paid support from one of the listed plexus support companies.
Since the code is free and available, any skilled programmer can fix and improve the tool and library at will.
Tests by independent users have proven that it is just as fast, even much faster than libwww in similar test cases.
When using links, you get unparalleled speeds because libcurl is programmed in C and the language-specific alternatives (be it Perl, Python, PHP, tcl or something else) are often much slower.
All functions have their own detailed pages describing their actual functions and purpose. All interfaces have overview-style human pages describing the concepts that stick all functionality together: easy, multiple parsing, sharing, and URLs.
