💰 1. Why self-host in 2026

SaaS pricing has crept up across the board while open-source alternatives quietly closed the UX gap. The math now favors hosting your own stack — especially once you're paying for three or four overlapping tools.

None of these need a team to run. A single small VPS (a 2–4 GB box is plenty) running Docker Compose can host most of this list at once. The trade is setup time and your own backups in exchange for owning your data and dropping the recurring bill.
