Why switch to open source?
Open source software gives you control over your tools, your data, and your costs. You can inspect the code, self-host it on your own servers, customize it to your needs, and avoid vendor lock-in.
OpenSourceFest makes the switch easier by showing you exactly which open source projects can replace the proprietary tools you're already using — with license type, GitHub activity, self-hosting options, and community size.
