What is the GNU GPL?

The GNU General Public License (GPL) is a free software license that guarantees end users the freedom to use, study, share, and modify the software. It is one of the most widely used free software licenses and is designed to ensure that software remains free and open for all users.

What are the key features of the GNU GPL?

The GPL is a copyleft license, which means that any derivative works of GPL-licensed software must also be licensed under the GPL. It guarantees certain freedoms to end users, including the freedom to use, study, share, and modify the software. The GPL is also compatible with many other open source licenses, allowing GPL-licensed code to be combined with code released under other licenses.

Can I use GPL-licensed code in my commercial project?

Yes, you can use GPL-licensed code in a commercial project, but any modifications or derivative works you create must also be licensed under the GPL.

Do I need to release the source code of my project if I use GPL-licensed code?

Yes, if you use GPL-licensed code in your project and distribute the resulting software to others, you must also release the source code of your project under the GPL.

Are there any restrictions on how I can use GPL-licensed code?

The main restriction of the GPL is that any modifications or derivative works you create must be licensed under the GPL and be made available to others under the same terms.

Can I use GPL-licensed code in my closed-source project?

No, if you use GPL-licensed code in a closed-source project, you would be violating the terms of the GPL, as the GPL requires that any derivative works be licensed under the GPL and be made available to others under the same terms.

Is the GPL compatible with other licenses?

How do I comply with the GPL if I use GPL-licensed code in my project?
