FOSS software to self-host

Free and Open Source Software (FOSS) refers to software that is both free to use and whose source code is openly available. This means anyone can view, modify, and distribute the code, fostering transparency and community-driven development.

FOSS licenses such as MIT, Apache 2.0, GPL, and AGPL ensure that software remains accessible and modifiable. Choosing FOSS for self-hosting gives you full control over your data and infrastructure without vendor lock-in.
