VAULT OPUS: The Infinity Cloud Storage Project

Vault Opus is an “infinite” cloud storage project: a self-hosted, open-source storage engine and virtual file system (VFS) that turns your personal Discord server into a secure, controlled cloud storage system. It uses the Discord CDN as a storage backend, enabling a high-performance file system without centralized servers or subscription fees.

Why use Vault Opus?

Completely free

No paywalls, no ads, fully open source. The entire codebase is free to use and modify.

Unlimited storage

Leverages Discord’s infrastructure to store files, effectively giving you unlimited storage capacity.

Privacy-first, locally run

Runs entirely on your machine. You control storage permissions. No accounts, no registration, and zero telemetry. Your data stays unseen by us because it never reaches us.

Security first

Files are encrypted locally before leaving your device. Uses strong encryption like Argon2id and AES. Data remains encrypted in transit and only decrypted locally.

Atomic data integrity

Supports soft and hard atomic operations so uploads and downloads are protected from corruption during interruptions.

File and folder versioning

Every upload is versioned. You can upload, download, or delete different versions of your files effortlessly.

Portable Volumes (.vov)

Group files into “Volumes” and export them as secure portable packages. These can be shared with trusted users or stored offline as encrypted backups.

Integrated terminal

Monitor the core engine in real time. View status updates, task IDs, and raw engine output directly from the mobile interface.
