Self-hosting is about strategic sovereignty

Despite the “self-host everything” hype, digital sovereignty isn’t about replacing every SaaS, very often we just need portable apps.

The most meaningful reasons to self-host are:

1. Offline-first or air-gapped use:
   Tools like Joplin, Standard Notes, KeePassXC, or LibreOffice Portable work without internet. You don’t need to host them, you just carry them on a USB drive. These are portable apps, not server apps.

2. Replacing cloud services you actually rely on:
   Only self-host what you’d otherwise pay for or trust with sensitive data:

   • Password manager (Bitwarden) instead of 1Password
   • File sync (Nextcloud) instead of Dropbox
   • Email (Mailcow) instead of Gmail
   • Media server (Jellyfin) instead of YouTube/Spotify

3. Digital nomads & remote collaborators:
   If you’re working across time zones or unreliable networks, having your own secure, always-on hub (via Cloudflare, Pangolin, Tailscale, etc.) means you’re never locked out by corporate outages, rate limits, or account bans.

4. Cost control at scale:
   Running 5–10 personal tools on one mini-PC costs €0/month vs. €30–€100 in SaaS subscriptions. But only if you value long-term ownership over short-term convenience.

🚫 What not to self-host:

• Apps that require massive infrastructure e.g., real-time global collaboration
• Services that depend on external APIs you can’t replicate e.g., Stripe, though you can self-host the frontend and proxy securely
• Anything you’ll abandon after two weeks because maintenance outweighs benefit

🔁 The Smart Balance: Portable + Self-Hosted Hybrid

Use Case	Best Approach
Writing notes offline	Portable app (Joplin on USB)
Syncing notes across devices	Self-hosted (Standard Notes + Tunnel, or Tailscale)
Managing passwords on one machine	KeePassXC (portable)
Sharing secure logins with family	Vaultwarden (self-hosted)
Editing documents while traveling	OnlyOffice Desktop (portable)
Collaborating on docs with team	CryptPad or Nextcloud Office (self-hosted)

Bottom Line

Self-host only what gives you real leverage: privacy, cost savings, reliability, or creative control.
For everything else, use portable apps, open formats, and offline-first tools. That’s not “less” self-hosting; it’s smarter digital independence.

Your instinct should align with a mature, sustainable homelab philosophy: minimal server footprint, maximum personal agency.
