Frequently asked questions
What does open source mean?
The source code is public under a license that lets anyone use, study, change and share it. That usually means the app is free, and nobody can lock you in.
Are these apps really free?
Yes, every app here is free to download or self-host. Some projects sell an optional hosted version or support plan, but the open-source app itself costs nothing.
How did you choose them?
Each app has an OSI-approved license, checked in its own repository in October 2026, and recent development. We left out “source-available” apps whose licenses limit commercial use, such as n8n and NocoDB.
What does self-hosted mean?
You run the app on your own server or computer instead of the company’s cloud. You keep your data, but you look after the updates.
