Self-Hosted Project Cloud
A private, project-first file cloud for TrueNAS — resumable chunked uploads, on-the-fly previews, and trusted-device auth. Your files stay yours.
The problem
Cloud storage is a subscription you do not control. The goal was a self-hosted alternative that matches the UX without the rent or the data exposure.
The approach
Files are the source of truth on disk; SQLite is a rebuildable index over them. Large uploads resume via 8 MiB chunks with compare-and-swap concurrency control; image, video, and PDF previews generate on demand; auth is scrypt with sliding sessions and 6-digit device pairing.
Highlights
- Resumable chunked uploads with compare-and-swap concurrency control
- Path-traversal-hardened storage; scrypt + sliding-session + device-pairing auth
- Files are the source of truth — SQLite is a rebuildable index, not the system of record
Results
- 352 passing tests, green CI
- Resumable chunked uploads with concurrency safety
- Shipped as a versioned Docker image
- Path-traversal-hardened storage layer
When the stakes are correctness and data you control, this is how we build it.
