Koofr Review 2026: The Best Cloud Storage You've Never Heard Of

Koofr has been quietly building the most interesting supporting cast in cloud storage since 2012. While Dropbox and Google argue about collaboration features and OneDrive bundles Office apps, Koofr built a product that connects to all of them for free, added WebDAV and rclone compatibility that power users love, set up shop in Slovenia under EU GDPR jurisdiction, and charges $21/year for 100GB.

Twenty-one dollars a year.

The trade-offs are real — Koofr doesn't do zero-knowledge encryption, the interface is utilitarian, there's no collaboration layer, and the annual-only billing means you're committed once you buy. But for users who want cheap EU cloud storage that plays nicely with everything else they already use, Koofr is an underrated find.

What does Koofr actually cost in 2026?

Koofr's pricing is annual-only with no monthly billing option. That's the whole structure:

• Free: 10GB, permanent, no credit card required
• Basic 25GB: $9/year
• S 100GB: $21/year
• M 250GB: $48/year
• L 1TB: $96/year
• XL 2.5TB: $192/year

At $21/year for 100GB, Koofr is the cheapest 100GB cloud storage we cover by a significant margin. Google One charges $23.88/year for 100GB. iCloud+ is $11.88/year but Apple-only. pCloud's 500GB annual plan is $99/year. Koofr's pricing is consistently 30-60% cheaper than name-brand alternatives at every storage tier.

The annual commitment means no monthly refunds. If you buy 100GB and realize after two months it's not the right tool, you're into the full year. The free 10GB tier is generous enough to evaluate the product before committing, which partially mitigates this.

No lifetime plans, no monthly plans, and no storage add-ons. You pick a tier and pay for the year.

The connected accounts feature — why Koofr is different

This is what separates Koofr from most of the services in this review set, and it's the reason power users who discover Koofr tend to stick with it.

You can connect your existing Dropbox, Google Drive, and OneDrive accounts to Koofr for free. Once connected, your external accounts appear as folders within Koofr's interface. You can browse, copy, and move files between your Koofr storage and your connected accounts from a single file manager. No separate app per service, no switching contexts.

The practical use cases that make this genuinely useful:

• Unified backup: Move files from your Google Drive into Koofr storage for a second copy in a different jurisdiction, without downloading and re-uploading through your local machine.
• Migration: If you're leaving Dropbox for Koofr, connect both accounts and transfer files directly in-browser.
• Multi-cloud file management: Browse Google Drive, OneDrive, and Koofr in the same sidebar without leaving the app.

The feature is free on all tiers, including the 10GB free plan. You can connect multiple external accounts. The connection uses OAuth, so Koofr gets read/write access to your connected storage — be aware you're trusting Koofr to access those accounts. Revoke the connection from your Google/Dropbox/Microsoft account settings at any time.

WebDAV, rclone, and why developers love Koofr

Koofr supports WebDAV natively on all paid plans (and the free tier with a generated password). This means:

• Mount Koofr as a network drive in Windows Explorer or macOS Finder without installing a desktop client
• Access Koofr from any WebDAV-compatible application (DAVx⁵ on Android, any file manager with WebDAV, FTP clients, etc.)
• Use rclone to script file transfers, automated backups, and cloud-to-cloud moves
• Connect from FTP/SFTP clients using Koofr's FTP bridge

For r/selfhosted and r/DataHoarder communities, Koofr's WebDAV compatibility without needing to install proprietary software is the draw. You can back up a Linux server to Koofr via rclone without ever installing the Koofr desktop client. You can automate photo imports from your NAS. You can script nightly offsite copies of whatever you need.

The rclone integration specifically is clean — Koofr appears in rclone's supported backend list with native configuration support, not as a generic WebDAV hack. Tests in the r/selfhosted community consistently report reliable rclone performance on Koofr at the expected speed tier.

How fast is Koofr in real-world testing?

Koofr's speeds are adequate — not remarkable, not a bottleneck for everyday use. On a 400 Mbps connection, we averaged roughly 110-120 Mbps upload and 130-145 Mbps download on large files. Consistent, no throttling we could detect, no rate limiting on sustained transfers.

For rclone-based workflows that involve moving many small files, Koofr performs similarly to other WebDAV providers — the per-file overhead of WebDAV is real and a bulk transfer of 50,000 small files is slower than the same total size in larger files. Use rclone sync with --transfers set appropriately for your connection.

There is no block-level sync. File edits trigger a full re-upload. For document workflows this is irrelevant; for large file workflows it matters.

Security Analysis

Koofr's security model is standard and honest about it: AES-256 at rest, TLS 1.2 in transit, Koofr holds the encryption keys. There is no zero-knowledge option. Koofr can technically access your files, and they would respond to a valid Slovenian court order with file content.

Slovenia is an EU member state, which means GDPR applies, data is subject to European data protection law, and cross-border data transfers require adequacy decisions or Standard Contractual Clauses. Slovenia is not a Five Eyes member. US government requests cannot directly compel a Slovenian company to produce records outside of MLAT requests through EU channels, which are slower and more restricted than domestic US legal process.

Koofr's privacy policy is notably clean for a small company — explicit about what they collect (email, usage data), what they don't (they don't sell data, don't run analytics for third parties, don't serve ads). The business model is straightforward: you pay for storage, they store your files. No monetization of user data.

Two-factor authentication is available via TOTP (authenticator apps). Enable it — Koofr's lack of zero-knowledge encryption means account security is your main line of defense.

The desktop client and app ecosystem

Koofr's desktop clients for Windows, Mac, and Linux exist and work reliably for basic folder sync. They're functional without being impressive — no virtual drive, no Files On-Demand, just a sync folder on your local disk that mirrors your Koofr cloud. Think early Dropbox, not modern OneDrive.

Mobile apps for iOS and Android cover photo backup, file browsing, and basic sharing. The photo backup is reliable and runs in the background without the battery drain issues that some small-provider apps have exhibited.

The web interface is Koofr's strongest access point. Clean, fast, and where the connected accounts feature shines. The multi-account file browser works well in a desktop browser and is the interface most power users spend the most time in.

No collaboration features — no shared editing, no real-time co-authoring. Koofr is file storage and sharing, not a workspace. Share folders with external users for read-only or read-write access; that's the collaboration ceiling.

Where Koofr falls short

No zero-knowledge encryption. If your threat model requires the provider to be cryptographically incapable of reading your files, Koofr isn't the answer. For that, look at Proton Drive, Internxt, or Sync.com.

Annual billing only. No monthly plans means a 12-month commitment with no trial refund beyond what the free tier shows you. Most competitors offer monthly billing.

Limited collaboration. No live co-editing, no commenting, no task assignment. Koofr is a file manager, not a workspace.

Smaller support infrastructure. Koofr is a small Slovenian company with a proportionally small support team. Email support works, response times are usually under a day, but don't expect 24/7 phone support.

No versioning on free tier, limited on paid. File versioning is available on paid plans but the retention window and interface are less robust than Dropbox or pCloud. For critical document recovery, test the versioning before relying on it.

Pros and Cons

Who should actually use Koofr?

• Multi-cloud users who want to manage Dropbox, Google Drive, OneDrive, and additional EU storage from a single interface
• Power users and homelabbers who want WebDAV, rclone, or FTP access to EU cloud storage without paying enterprise prices
• Budget buyers who want 100GB or 250GB of EU-jurisdiction storage and don't need zero-knowledge encryption
• Privacy-conscious EU users who want a simple storage service that doesn't monetize their data
• Linux users who want a first-party desktop client from an EU provider

Skip Koofr if you need zero-knowledge encryption, monthly billing flexibility, collaboration features, or a brand name that'll appear in a compliance audit without explanation.

FAQ

Does Koofr actually let me connect my Google Drive and Dropbox for free?

Yes, on all plans including the free tier. Go to your Koofr account settings, find "Connected accounts," and authenticate your Dropbox, Google Drive, or OneDrive. Once connected, those accounts appear as folders in Koofr's interface. You can browse, copy, and move files between accounts from Koofr's web app or desktop client. Koofr doesn't copy files to your Koofr storage when you connect — files stay in their original account until you explicitly move or copy them. You're granting Koofr OAuth access to those accounts, which you can revoke anytime from the respective provider's app settings.

How does Koofr WebDAV work?

Go to Koofr's account settings and generate an app password specifically for WebDAV access. Use that password with the WebDAV URL Koofr provides to mount Koofr as a drive in Windows (Map Network Drive), macOS (Connect to Server), or via rclone/DAVx⁵ on Android. WebDAV access is available on all paid plans and on the free tier with the app password method. For rclone specifically, Koofr is a named backend in rclone's config — type rclone config and select Koofr from the provider list.

Is Koofr GDPR compliant?

Yes. Koofr is headquartered in Ljubljana, Slovenia, an EU member state, and processes data under GDPR. They publish a privacy policy that's explicit about what data they collect and don't collect, and they don't engage in ad targeting or third-party data sales. For users who specifically need EU data residency (data stored on servers inside the EU), verify with Koofr directly where their server infrastructure sits — like most Slovenian tech companies, they use a mix of owned and leased infrastructure.

How does Koofr compare to pCloud?

pCloud offers zero-knowledge encryption (via pCloud Crypto add-on) and lifetime plans, which Koofr doesn't. pCloud has faster speeds and a more polished interface. Koofr is significantly cheaper ($21/year for 100GB vs pCloud's roughly $100/year equivalent) and adds the multi-cloud connection feature that pCloud lacks. If price is primary and you don't need zero-knowledge, Koofr wins. If you want lifetime pricing, a more established brand, or pCloud's Crypto option, pCloud is worth the premium.
