💰 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.
(self-hosted)
on your infra
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.

🎯 3. Rules for adopting them
- Migrate one tool at a time. Swapping your whole stack in a weekend guarantees you'll lose data or give up halfway.
- Back up before you trust it. Self-hosted means self-responsible — set up automated backups (even a daily cron + rsync) before you rely on it daily.
- Start with the highest-friction subscription. If you're paying for Notion, Calendly, and Postman, cancel the one that annoys you most first — that's where the motivation to stick with the swap comes from.
- Docker Compose is your friend. Most of these ship a ready-made
docker-compose.yml— a few minutes to first login is normal.
