Frequently Asked Questions
Common questions about this license

What is the LGPL license?

The LGPL (Lesser General Public License) is a free software license that allows linking to proprietary software, provided modifications to the LGPL-covered library are released under the same license.

Can an LGPL license be used commercially?

Yes, software under LGPL can be used commercially. However, modifications to the LGPL-covered components must be shared under the LGPL.

What is the difference between GPL and LGPL?

The LGPL is less restrictive than the GPL. While the GPL requires that derivative works also be licensed under the GPL, the LGPL allows linking to proprietary software without imposing the same requirement.

What is the difference between MIT and LGPL?

The MIT license is a permissive license with minimal restrictions, while the LGPL imposes conditions on modifications and requires sharing changes to the LGPL-covered components.
