Why open source alternatives?
Every SaaS you pay for is a monthly bill, a data-sharing decision and a vendor lock-in risk. Open source alternatives give you ownership: install on your own server, run forever without a subscription, and keep your data inside your walls. Some are drop-in; others ask you to learn new habits. We tell you which is which.
