Koofr

What Is Koofr?

The cloud storage market has consolidated into a handful of giants — Dropbox, Google Drive, OneDrive, iCloud — each operating within its own walled garden. Your photos sit in Google Drive. Your work documents live in OneDrive. Personal files are scattered across Dropbox. Switching between apps, managing separate storage quotas, and maintaining mental models of where things live has become a background tax on digital life.

Koofr, a Slovenian service founded in 2012, takes a fundamentally different approach to this fragmentation. Rather than competing with the storage giants head-on, it positions itself as a unification layer: connect your existing Dropbox, Google Drive, OneDrive, and Amazon S3 accounts, and manage all your files from a single interface. You can move files between providers, search across all your cloud accounts simultaneously, and use Koofr's own EU-hosted storage as a privacy-first home base.

Based in Ljubljana, Koofr is operated by Koofr d.o.o., a Slovenian company that stores all native data in EU data centres. It serves a niche that the major providers have no incentive to fill — cross-cloud file management with European data sovereignty — and does so at prices that make the big names look predatory. Storage starts at EUR 0.50 per month for 25 GB, with no file size limits on uploads even on the free tier.

Koofr will not replace Google Drive for teams deeply embedded in Google Workspace. It will not replace Dropbox for businesses that depend on Dropbox Paper and advanced sharing workflows. But for individuals and small teams who want to consolidate their scattered cloud storage into one EU-hosted interface without abandoning their existing accounts, Koofr occupies a genuinely unique position.

Key Features

Multi-Cloud Aggregation

Koofr's defining feature is the ability to connect external cloud storage accounts — Google Drive, Dropbox, OneDrive, and Amazon S3 — and browse, search, and manage files from all of them within a single interface. Connected accounts appear as folders alongside your native Koofr storage. You can copy or move files between providers, which is useful for migrating data or consolidating backups. This is not merely a list of shortcuts; Koofr provides genuine file operations across cloud boundaries, something no major storage provider offers natively.

No File Size Limits

Unlike Dropbox (which restricts uploads via the web interface) and Google Drive (which has limits on individual file sizes for certain formats), Koofr imposes no file size limits on uploads, even on the free plan. For users working with large video files, design assets, or database backups, this removes a friction point that affects workflows on competing services. Upload and download speeds depend on your connection and Koofr's infrastructure, but the absence of artificial caps is a meaningful differentiator.

Koofr Vault

Koofr Vault provides client-side encryption for specific folders. Files placed in the Vault are encrypted on your device before upload, using a password that Koofr never sees. This means Koofr itself cannot read your encrypted files — a zero-knowledge architecture for your most sensitive data. The Vault is available on paid plans and works across desktop, web, and mobile. It is optional rather than default, which means unencrypted files remain readable by Koofr's systems. Privacy purists may prefer services with encryption enabled by default, but the opt-in Vault model offers a practical balance between convenience and security.

Desktop and Mobile Sync

Koofr provides desktop sync clients for Windows, macOS, and Linux, along with mobile apps for iOS and Android. The desktop client keeps selected folders synchronised between your local machine and Koofr's cloud storage. Mobile apps support automatic photo and video backup, which is particularly useful for users looking to avoid Google Photos or iCloud for privacy reasons. WebDAV support extends compatibility to third-party file managers and applications, and rclone integration opens up advanced backup and transfer scenarios for technical users.

File Sharing

Sharing works through link-based sharing with optional password protection and expiry dates. You can share files and folders from your Koofr storage or from connected cloud accounts. The sharing interface is straightforward but lacks the collaborative features of Google Drive (real-time editing, commenting) or Dropbox (Dropbox Paper, team spaces). Koofr is a storage and file management tool, not a collaboration platform.

Pricing

Koofr's pricing is remarkably competitive for EU-hosted cloud storage. The Free tier provides 10 GB of storage with no file size limits, multi-cloud connection support, and WebDAV access. For a personal user looking to consolidate cloud accounts, 10 GB of native Koofr storage alongside connected external accounts may be sufficient.

The Starter plan at EUR 0.50 per month delivers 25 GB of storage — the kind of price point that makes you double-check you have read it correctly. It includes Koofr Vault encryption and priority support.

Standard at EUR 2 per month provides 100 GB, and Extreme at EUR 10 per month gives you 1 TB. Even at the top tier, Koofr is meaningfully cheaper than Dropbox Plus (approximately EUR 12/month for 2 TB) while offering the multi-cloud aggregation that Dropbox does not provide.

Annual billing reduces these costs further. Koofr also periodically offers lifetime storage deals through partner platforms, which have built a dedicated following among privacy-conscious users looking to eliminate recurring cloud storage costs entirely.

The value proposition is strongest for users who want modest EU-hosted storage combined with the ability to manage their existing Google Drive or Dropbox accounts from a single interface. If you need 2 TB+ of raw storage, Koofr's pricing advantage narrows.

EU Compliance & Privacy

Koofr d.o.o. is a Slovenian company, operating within the EU under full GDPR obligations. All native Koofr storage is hosted in EU data centres, and the company explicitly states that it does not mine user data for advertising or sell data to third parties.

The Koofr Vault feature adds an additional layer for sensitive files: client-side encryption ensures that even Koofr cannot access Vault contents. For files stored outside the Vault, standard server-side encryption applies, meaning Koofr has technical access to the data (as with any non-zero-knowledge cloud provider).

When connecting external accounts like Google Drive or Dropbox, your data in those services remains subject to those providers' privacy policies. Koofr acts as an access layer but does not re-host or duplicate your external data unless you explicitly copy files into Koofr storage.

For European users concerned about US cloud providers and the CLOUD Act, storing files in Koofr's native storage (particularly within the encrypted Vault) provides a straightforward path to EU data residency with no transatlantic data transfers.

Who It's Best For

Privacy-conscious individuals who use multiple cloud storage services and want a single EU-hosted interface to manage all their files without abandoning existing accounts.

European professionals and small businesses who need affordable, GDPR-compliant cloud storage without the complexity or cost of enterprise solutions.

Technical users who value WebDAV and rclone support for advanced backup, sync, and migration workflows across multiple cloud providers.

Budget-minded users looking for the lowest-cost entry point into EU-hosted cloud storage, with the option to scale from free to 1 TB as needs grow.

The Verdict

Koofr is not trying to be the next Dropbox. It is filling a gap that the major providers cannot fill: a cross-cloud aggregation layer with EU hosting, no file size limits, and pricing that starts at less than a cup of coffee per month. The desktop client is less polished than Dropbox's, the brand is less recognised, and client-side encryption is opt-in rather than default. But for the specific problem of managing scattered cloud storage from a single, privacy-respecting EU base, Koofr is without a direct competitor. It earns 7.2 overall, with top marks for value (8.5) and compliance (8.5).

Frequently Asked Questions

Can Koofr replace Dropbox or Google Drive entirely?

For file storage and sync, Koofr can serve as a primary replacement. However, it lacks real-time document editing, team collaboration spaces, and the deep OS-level integration that Google Drive and Dropbox provide. If your workflow depends on Google Docs or Dropbox Paper, Koofr works better as a complementary storage layer than a full replacement.

Is the free tier useful long-term?

Yes. The free tier provides 10 GB of Koofr storage plus the ability to connect and manage external cloud accounts. If you primarily use Koofr as a multi-cloud management layer rather than a primary storage destination, the free tier may be sufficient indefinitely.

How secure is Koofr Vault?

Koofr Vault uses client-side AES-256 encryption. Files are encrypted on your device before upload, and the encryption key is derived from your Vault password, which Koofr never stores or transmits. If you lose your Vault password, Koofr cannot recover your encrypted files. This is genuine zero-knowledge encryption for the Vault folder.

Does Koofr work with rclone?

Yes. Koofr has native rclone support, making it compatible with rclone's extensive toolkit for syncing, copying, and mounting cloud storage. This is a significant advantage for Linux users and those with advanced backup automation requirements.

Is Koofr suitable for team use?

Koofr is primarily designed for individual users and does not offer team management features, shared workspaces, or administrative controls. For team file sharing and collaboration, solutions like Nextcloud or ONLYOFFICE DocSpace are better suited. Koofr excels as a personal multi-cloud storage manager.
