What is an open-source alternative?
It is software with publicly available source code that does the same job as a commercial product. Most of the alternatives listed here can be self-hosted, so your data stays on a server you control and there are no per-seat subscription fees.
Are open-source alternatives really free?
The software is free to use and modify. Self-hosting it means you pay only for the server, often a few dollars a month for a small VPS. Some projects also sell a managed cloud version if you would rather not run it yourself.
How do you choose which alternatives to list?
We match each commercial product with self-hosted apps that cover the same core use case, then rank them by GitHub stars, recent commits and release activity. Archived or abandoned projects are left out.
