Which NAS for self-hosting?

Minimum 4-bay with Intel x86 (no ARM!) and 8 GB RAM. Synology DS923+, QNAP TS-464, or DIY with N100. For 10+ containers: 16+ GB RAM.

How much does self-hosting save?

Realistically $200-400/year by avoiding cloud subscriptions. Amortizes a 4-bay NAS in 2-3 years.

Do I need Docker knowledge?

For Synology Container Manager and Unraid: minimal (UI-based). For more complex stacks: basic docker-compose helps. 2-3 hours of learning is enough for the basics.

Self-Hosting on NAS: Replace Cloud Subscriptions With Your Own Services

Updated: 2026-04-29

Dropbox, 1Password, Google Photos, smart home cloud – all great, all expensive. With a 4-bay NAS you can self-host most of these services and save $200-400/year in subscriptions. Practical list below.

Short version

Self-hosting pays off from a 4-bay NAS with at least 8 GB RAM. Nextcloud replaces Dropbox, Vaultwarden replaces 1Password, Immich replaces Google Photos, Home Assistant replaces SmartThings. All run as Docker containers, setup time per app ~30-90 minutes.

Hardware requirements

Minimum: Synology DS224+ / DS923+ or equivalent. 4-8 GB RAM, x86 CPU (no ARM!).
Comfortable: 4-bay with Intel N100/N305 or Ryzen 5, 16 GB RAM, M.2 NVMe cache.
Power: DIY mini-PC with 32 GB RAM for 10+ containers in parallel.

Top self-hostable apps 2026

Nextcloud (cloud storage / office). Replaces Dropbox, Google Drive, Office Online. Native app on Synology, otherwise Docker. RAM: ~1 GB.

Vaultwarden (password manager). Bitwarden-compatible OSS. Replaces 1Password (~$36/year), LastPass. RAM: 100 MB. Easiest immediate savings app.

Immich (photo management). Google Photos clone with auto-upload, face recognition, ML tagging. Needs GPU or Coral USB for AI features. RAM: 2-4 GB.

Home Assistant (smart home). Replaces SmartThings, Hue, Apple HomeKit hub. Local control, add-ons via HACS. RAM: 1-2 GB.

Pi-hole or AdGuard Home (DNS adblocker). Blocks ads network-wide. RAM: 100-300 MB.

Jellyfin (media server). Plex alternative without cloud dependency. Hardware transcoding via Intel Quick Sync. RAM: 1-2 GB.

Paperless-ngx (document management). Scans PDFs, OCR-indexes, searchable. 10-year tax archive? Done. RAM: 1 GB.

What you save (example)

Dropbox 2 TB: $120/year → Nextcloud: $0
1Password Family: $65/year → Vaultwarden: $0
Google One 2 TB: $120/year → Immich: $0
SmartThings sub: $50/year → Home Assistant: $0
NextDNS Pro: $25/year → AdGuard Home: $0

Total savings: ~$380/year. NAS amortizes in 2-3 years just from self-hosting.

Setup tips

Docker over native apps where possible. Easier updates, reproducible snapshots. Synology Container Manager, Unraid Docker UI, TrueNAS Apps.

Reverse proxy: Caddy or Nginx Proxy Manager as frontend. Domain via DuckDNS, Let's Encrypt for HTTPS. ~30 min setup.

Backup: Container volumes are data – include in backup. Export Vaultwarden DB separately.

Reverse proxy + VPN: Tailscale or WireGuard for external access. No open port-forwarding to the internet.

Security notes

Never expose containers directly (port 80/443 forward) without HTTPS reverse proxy
Enable 2FA on Vaultwarden + Nextcloud + Home Assistant
Regular updates (Watchtower for auto container updates)
Quarterly backup tests

Recommendation

Beginners: start with Vaultwarden (10-min setup, instantly $65/year saved). Then Nextcloud + Immich. Home Assistant last – steep learning curve but biggest payoff.
