Difference between GPL and LGPL

Main difference

GPL stands for General Public License. LGPL is like a modified version of GPL. It stands for Lesser General Public License. It limits your requirement to provide some of your code, but you must still disclose the modifications you implement. What you are allowed to keep private is proprietary material that links directly to the software. This allows you to change the software, create your own personal touch, and still protect your own material. The term GPL has a broader meaning and practicality compared to LGPL. LGPL has the potential to be transferred to GPL terms.

What is GPL?

The General Public License, or GPL as it is often called, is the most popular free software license and is used by many different projects, including the Linux kernel, the GNU tools, and literally hundreds of others. GPL is the foundation of open source software for programmers.

What is LGPL?

The LGPL is similar to the GPL, but is more designed for software libraries where you want to allow non-GPL applications to link to and use your library. If you modify the software, you still have to return the source code, but you can link to proprietary material without returning the source code to all of that.

Key differences

  1. The difference between the GPL and the LGPL is that with the LGPL, all the “work” does not have to be licensed under the same license.
  2. Unlike the LGPL, the GPL requires you to provide the code for all changes made to the software.
  3. Between the two GPLs is the foundation of open source software for programmers.
  4. LGPL is used for software libraries, as opposed to GPL runtime files.
  5. GPL offers a wide range of possible enhancements for the entire programming community.
  6. LGPL has the potential to be transferred to GPL terms.
  7. The term GPL has a broader meaning and practicality compared to LGPL.
  8. With both licenses, the person who wrote the code owns it. The license does not affect that.
  9. According to Black Duck Software research, the GPL is used much more than the LGPL.
