cURL Command Line Tool Free Download for Windows and Mac
cURL is free and open-source which hundreds of contributors and sponsors support. For all portability-related functionality, cURL is driven by libcurl. It is used for the transmission of data in command lines or scripts.
cURL Across Multiple Operating Systems
It is also used in vehicles, TVs, routers, printers, soundtracks, mobile devices, tablets, set-top boxes, and media players and is the 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, Meta link, and more. As you can see below, the number of features will make your head spin!
Exploring The Powerful Features
The cURL library supports a wide range of protocols, such as DICT, FILE, FTP, FTPS, Gopher, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMTP, SMTPS, Telnet and TFTP. cURL supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading, Kerberos, HTTP form-based upload, proxies, cookies, user+password authentication, file transfer resume, proxy tunneling, and a bushel of other useful tricks.
In addition, cURL is fully integrated with a variety of operating systems, including Windows, Mac OS X, Linux, AIX, Solaris, HP-UX, OpenVMS, z/OS, QNX, and other Unix flavors. cURL is also available as a library to be used in programming languages such as C, C++, Java, PHP, Python, Ruby, etc.
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.
Today, the library has been updated and improved greatly, with a large number of new features added to keep up with the ever-changing software landscape. Performance improvements, bug fixes, and security updates have all been incorporated into the library, making it a much more reliable and secure choice than ever before. In addition, the library’s user-friendly interface makes it easy to use and learn, making it a popular choice among developers.
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, macOS, Ultrix, QNX, OpenVMS, RISC OS, Novell NetWare, DOS, and many more, but not just Solaris, NetBSD, FreeBSD, HPUX, IRIX, AIX, and other systems.
These portable versions of cURL have been tested to work with a wide array of libraries and platforms, including OpenSSL, libssh2, SSPI, libidn2, libmetalink, and many more. This allows developers to integrate cURL into their existing applications and gives them access to powerful features such as file transfer, URL parsing, FTP uploading, and many more.
Additionally, cURL provides support for a wide range of protocols, including HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, LDAP, LDAPS, DICT, TELNET, FILE, IMAP, POP3, SMTP, RTSP, and more. This makes it an ideal tool for any developer looking to implement robust networking functionality into their application.
It’s a safe program, but there are a few exceptions. See libcurl -thread (3) for more information. Users should always take precautions when using this program and follow the recommended guidelines to ensure their security. To maximize safety, users should never enter personal information or sensitive data while using this program.
Additionally, users should always keep their software up-to-date, as this can help protect against any potential security vulnerabilities. Finally, users should be aware of any potential phishing attempts and be sure to only trust sources that are verified.
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.
- You can use only a hostname that has 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 most 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.
