Workerman is open source and free software, and the license agreement is MIT.
The MIT License is one of the most widely used software licensing terms. Compared with other common software licensing terms (such as GPL, LGPL, BSD), MIT has relatively loose software licensing terms. (Recommended study: workermantutorial)
The name of the MIT license comes from the Massachusetts Institute of Technology (MIT), also known as "X License" or The content of the "X11 License"
MIT is quite similar to the content of the 3-clause BSD license, but gives greater rights and fewer restrictions to the software licensee.
There are many groups that adopt the MIT license. For example, the famous ssh connection software PuTTY and X Window System (X11) are examples. Expat, Mono development platform library, Ruby on Rails, Lua 5.0 awards, etc. also adopt MIT licensing terms.
Licensee Rights

The authorized person can modify the authorization terms to the appropriate content according to the needs of the program.
Licensee Obligations
A copyright notice and a license notice must be included in the Software and in all copies of the Software.
Other important features
This license term is not a copyleft free software license term and is allowed to be used in free/open source software or non-free software (proprietary software) .
The content of MIT can be changed according to the needs of the program copyright owner. This is also the essential difference between MIT and BSD (The BSD license, 3-clause BSD license).
MIT terms may coexist with other licensing terms. In addition, the MIT terms are also free software licensing terms recognized by the Free Software Foundation (FSF) and are compatible with the GPL.
