The goal of the Sovereignty Stack is to replace corporate data silos with verifiable, self-hosted alternatives. This is not about finding a “clone” of a corporate service, but finding a tool that gives you ownership.

Warning: Self-hosting involves responsibility. Always follow the backup rules outlined in the Exit the Cloud Roadmap.

*The foundation that makes everything else possible.*

• Instead of a Proprietary Cloud ⇒ Try: Debian or Ubuntu Server on a “TinyMiniMicro” PC or Raspberry Pi.
• Instead of Manual Software Installs ⇒ Try: Docker or Podman (via Docker Compose) for isolated, portable services.
• Instead of Open Ports (Security Risk) ⇒ Try: Tailscale or WireGuard for a private, secure overlay network.

*Getting your documents and memories out of the walled garden.*

• Instead of Google Drive / Dropbox / iCloud ⇒ Try: Nextcloud (The “everything” suite) or Seafile (focused, high-performance file sync).
• Instead of Google Photos / Apple Photos ⇒ Try: Immich (modern, AI-powered, very similar to Google Photos) or PhotoPrism (robust indexing and organization).
• Instead of Evernote / Notion / OneNote ⇒ Try: Joplin (open source, supports Markdown) or Obsidian (local-first, highly extensible).

*Protecting your keys and your privacy.*

• Instead of LastPass / 1Password / Google Passwords ⇒ Try: Vaultwarden (a lightweight, Rust-based implementation of Bitwarden).
• Instead of Google/Facebook Login (OAuth) ⇒ Try: Authelia or Authentik for centralized authentication (SSO) across your own services.

*Owning the conversation.*

• Instead of Slack / Discord / WhatsApp ⇒ Try: Matrix (via the Element client) for a decentralized, federated chat protocol.
• Instead of Gmail / Outlook ⇒ Try: Mailcow or Poste.io (though email is the “final boss” of self-hosting—start with the others first).
• Instead of Google Calendar ⇒ Try: Nextcloud Calendar using the CalDAV standard.

*Breaking the algorithmic filter.*

• Instead of Google Search / Bing ⇒ Try: SearXNG (a privacy-respecting metasearch engine that aggregates results without tracking you).

— Pro Tip: Don't try to migrate everything in one weekend. Pick one category (like Passwords or Photos), get it stable and backed up, and then move to the next. 📚
