Why HoloTech

Built for the long term

Everything you expect from a modern cloud drive, without handing your data to someone else's computer.

  • End-to-end encryption

    Files are encrypted on your device before they leave it. Only you hold the keys — not us, not your hosting provider.

  • Every device, every platform

    Native clients for desktop and mobile keep folders in sync without manual uploads or browser workarounds.

  • Durable by design

    Redundant storage across your own disks and off-site copies protects against hardware loss and keeps retrieval fast.

  • Granular sharing

    Share a folder with a link, an expiry date, and a password. Revoke access in one click — the keys rotate with it.

  • Version history

    Every change is kept for 30 days. Roll back a single file or an entire folder to any point, in seconds.

  • Full data sovereignty

    One binary, your server, your rules. Move providers or go fully offline without export tools or permission slips.

Up in minutes

Three steps to your own cloud

  1. Deploy the server

    Run a single binary or one container on any VPS, NAS, or spare laptop. No external services required.

  2. Create your vault

    Set a passphrase and a second factor. Your encryption keys are derived locally and never leave your devices.

  3. Sync everything

    Install the clients, pick your folders, and watch every device converge — over LAN or across the world.

Zero-knowledge by default

Encryption that starts before upload

Your server only ever stores ciphertext. Metadata, filenames, and contents are sealed on your device with keys derived from your passphrase.

  • AES-256-GCM with per-file keys, wrapped by your vault key
  • Argon2id key derivation — brute force stays expensive
  • TLS 1.3 in transit, with automatic certificate handling
  • Time-based one-time codes as a mandatory second factor
  • A single auditable binary — no opaque plugin chain

We moved four terabytes of client work off a rented drive and onto a HoloTech box in our rack. Audit season stopped being a conversation.

Two syncs across continents and zero "where is the latest version" messages since we cut the team over to HoloTech.
