✓A spare laptop, mini PC, or Raspberry Pi is sufficient to run a robust self-hosted personal cloud.
✓Docker Compose streamlines service deployment and automated persistent backups.
✓Cloudflare Tunnels eliminate the need to open port forwards on your home router, safeguarding your network.
✓Automatic photo sync with facial recognition and document OCR replicates Google Photos and Google Drive functionality.
