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. Many open source tools are free to use, with optional paid plans for hosting or enterprise features.
OpenSourceFest makes the switch easier by showing you exactly which open source projects can replace the proprietary tools you're already using — with information on license type, GitHub activity, self-hosting options, and community size.
