Frequently Asked Questions About Open Source Software
What is open source software?
Open source software is code that is publicly available for anyone to view, modify, and distribute. Popular licenses include MIT, Apache 2.0, and GPL. Our directory features the best open source projects with permissive licenses.
What's the difference between MIT and Apache licenses?
MIT is a permissive license with minimal restrictions - you can use the code commercially with attribution. Apache 2.0 is similar but includes patent rights protection. GPL requires derivative works to also be open source.
Can I use open source software for commercial projects?
Yes! MIT and Apache 2.0 licensed projects can be used commercially. Just check the specific license terms - most require attribution in your documentation or source code.
How do I contribute to open source projects?
Start by finding a project you're interested in, read their contribution guidelines, and look for 'good first issue' labels. Fork the repository, make your changes, and submit a pull request.
What are GitHub stars and why do they matter?
GitHub stars indicate community interest and popularity. More stars typically mean better documentation, active maintenance, and community support. Our directory shows star counts to help you find quality projects.
