Apache 2.0

It is one of the most widely used licenses for open-source projects and is recognised by the Open Source Initiative (OSI). The Apache 2.0 license provides users with significant freedom to use, modify, and distribute the software, subject to certain conditions. One notable feature is that it allows for the inclusion of the licensed code in both open-source and proprietary projects. Additionally, it includes a patent grant, which helps protect contributors and users from potential patent-related issues.
