Frequently Asked Questions
What is open source software?
Open source software is software with source code that anyone can inspect, modify, and enhance. It is typically free to use and developed collaboratively by a community of developers.
How do I find the best open source alternatives?
You can browse open source alternatives by category, search by the commercial software you want to replace, or compare projects by GitHub stars, community activity, and features on OpenSourceProjects.cc.
What does "self-hosted" mean for open source projects?
Self-hosted means you can install and run the software on your own server or infrastructure, giving you full control over your data and customization, instead of relying on a third-party cloud service.
Why use open source projects instead of proprietary tools?
Open source software offers transparency, community-driven development, no vendor lock-in, and often zero licensing cost. You can audit the code for security, customize it to your needs, and benefit from contributions by thousands of developers worldwide.
Are open source projects free to use?
Most open source projects are free to download and use. Some offer paid hosting, support, or enterprise features, but the core software remains free under open source licenses like MIT, Apache 2.0, or GPL.
