Hoodik vs Filen: Self-Hosted Zero-Knowledge vs Managed E2E Cloud Storage

Filen and Hoodik are both end-to-end encrypted storage systems, which puts them in the top tier for privacy. Files are encrypted on your device before upload, and the server never has access to the keys. But they're aimed at different audiences and make different tradeoffs about how encrypted storage should actually be delivered.

The Core Difference: Managed vs Self-Hosted

Filen is a managed cloud service headquartered in Germany. You create an account, install their apps, and start storing encrypted files. Their infrastructure, their bandwidth, their uptime responsibility. You get 10 GB free and can upgrade to paid plans for more storage.

Hoodik is self-hosted software. You deploy it on a server you control, and your storage is limited only by your hardware or attached object storage. There's no free tier in the traditional sense — you need a server to run it on — but there's also no monthly subscription to the software itself.

This distinction shapes everything else: features, cost structure, operational responsibility, and trust model.

Encryption Approach

Both systems encrypt files client-side with strong symmetric ciphers. Filen uses AES-256-GCM. Hoodik defaults to AEGIS-128L (a hardware-accelerated AEAD cipher) and also supports ChaCha20-Poly1305 and Ascon-128a.

Both generate per-file encryption keys, encrypt those keys with the user's master key, and only store encrypted blobs on the server. Neither service can read your files.

Where they differ is search. Filen's search operates on encrypted metadata client-side — it can only search filenames you've previously decrypted on that device. Hoodik takes a different approach: it tokenizes search terms using a BERT language model, hashes each token with SHA256, and sends only hashes to the server. The server can then match against pre-computed hashes stored at upload time. This means you get server-side search across your entire file collection without the server ever learning what you're searching for.

Where Filen Wins

The desktop sync client is Filen's standout feature. It offers five sync modes: two-way sync, local-to-cloud backup, cloud-to-local mirror, local-to-local copy (through cloud), and cloud-to-cloud. It handles conflict resolution, can be configured per folder, and is generally reliable. If you need your local filesystem and cloud storage to stay in sync automatically, Filen has a real advantage. Hoodik doesn't currently have a desktop sync client.

File versioning is also notable. Filen keeps previous versions of your files — if you accidentally overwrite a document, you can roll back. Hoodik doesn't have versioning yet; what you upload is what's stored.

On sharing: both support password-protected links with expiration dates, but Filen adds download count limits and account-to-account sharing. Hoodik's password mechanism is distinctive — the link key in the URL fragment acts as the password. If you omit it from the shared URL, recipients must enter it manually via a UI prompt.

10 GB of free encrypted storage with no time limit is a genuine offering. You can try Filen, use it for small-scale storage, or keep it as a backup target without spending anything. With Hoodik, you need a server — even a cheap VPS costs a few dollars a month.

Like any managed service, Filen handles infrastructure, updates, backups, and reliability. You don't think about disk health, RAM usage, or security patches. For many people, that's worth the subscription cost.

Where Hoodik Wins

Your files live on hardware you control. No company can change pricing, modify terms, sunset the service, or comply with a legal request to hand over your data — because your data isn't on their servers. You choose the jurisdiction, the hardware, the network, everything.

Filen's client apps are open source, but their server is proprietary. You trust that it does what they claim. Hoodik's server (Rust, Actix-web) is source-available and auditable — you can read exactly how data is stored, verify that encryption is preserved end-to-end, compile from source, or fork the project.

Storage limits matter at scale. Filen caps out at their highest paid tier. With Hoodik, your limit is your disk — or effectively unlimited with S3-compatible object storage. Backblaze B2 at $6/TB/month means a large media library or archive isn't a pricing conversation.

The BERT + SHA256 tokenized search is worth calling out specifically. Most encrypted storage systems either skip search entirely or do it client-side only, which means it only covers files you've already synced to that device. Hoodik gives you server-side search across your entire collection without the server ever learning what you're looking for.

Hoodik runs in about 20 MB of RAM as a single Docker container. Deploy it on the smallest available VPS and co-host it alongside other services without resource contention concerns. And if you want to store encrypted blobs on Backblaze B2, Wasabi, MinIO, or AWS S3 — it's natively supported. Separate compute from storage, use the cheapest object storage available, keep multiple replicas across providers.

Cost Comparison

Filen's pricing is straightforward: free tier (10 GB), then paid plans starting around €3-4/month for more storage.

Hoodik's cost is your infrastructure cost. A Hetzner Cloud CX22 (2 vCPU, 4 GB RAM, 40 GB disk) runs about $4/month. Add a 1 TB storage volume for another $5/month. That's $9/month for 1 TB of self-hosted encrypted storage with full control. At larger scales, self-hosting becomes dramatically cheaper — especially with object storage backends.

The Decision

If you want encrypted cloud storage that works like Dropbox — install, sync, forget about it — and you value the desktop sync client, file versioning, and zero operational responsibility, Filen is one of the better managed E2E encrypted storage services available.

If you want to own your infrastructure, need more than a few terabytes, or prefer open source server code you can audit — Hoodik gives you zero-knowledge encryption on your own terms. The tradeoff is operational responsibility and a thinner feature set for sharing and sync.

Both keep your files encrypted end-to-end. The decision is about how you want that delivered.
