Frequently Asked Questions
What is the most popular open source license?
The MIT License is the most popular permissive license allowing commercial use, modification, and private use with minimal restriction.
What is the difference between MIT and GPLv3?
MIT is permissive and allows proprietary derivative works, whereas GPLv3 is copyleft requiring derivative projects to also be open source under GPLv3.
Why is having a LICENSE file important?
Without a license, default copyright laws apply, meaning nobody has permission to copy, modify, or distribute your code.
