🚀 Why Sovereign Infrastructure?

Every SaaS you pay for is a piece of your sovereign control you are leasing. The mission of AltStack is to provide the data and deployment configurations necessary to replace the "Big Tech" stack with a Sovereign Stack you own.

This repository serves as the Data HQ for The AltStack. Every tool listed here is vetted for quality, activity, and self-hostability. See CRITERIA.md for the full vetting standards.
