Worth knowing
Filen
- Prices are listed in euros only; Filen says taxes and transaction fees are included in them.
- Free accounts lose their data after 3 months without a login, following reminder emails.
- Lifetime plans are no longer sold: the pricing FAQ says they were removed for an indefinite period.
- WebDAV and S3 access require a server that the user hosts through the desktop app or CLI, because files are encrypted on the device.
Koofr
- Prices are in euros and include 22% VAT, so the final amount depends on the buyer's country. Only yearly subscriptions are sold.
- Only files placed in Koofr Vault are client-side encrypted, and the Vault cannot be opened in the desktop app.
- The free plan cannot connect external clouds or use Office for the web, and its public links expire after 14 days.
- Local folders in the desktop app start at the Suitcase tier, which begins at 250 GB.
Key features
Filen
- Zero-knowledge encryption by default
- Files are encrypted on the device with AES 256-bit before upload, and Filen states that it cannot access them. Encryption is part of every plan, the free one included.
- Sync and network drive
- Desktop apps for Windows, macOS and Linux sync folders in five modes, with one-way and two-way among them, and can mount the cloud as a network drive in the file explorer.
- Encrypted sharing
- Files and folders are shared with other Filen users or through public links, and the shared content stays encrypted. Earlier versions of files can be restored from version history.
- Notes and chats
- Encrypted notes support rich text, markdown, checklists and code and can be edited with other users in real time. Encrypted chats carry messages and files between Filen users.
- Open source apps and developer tools
- Filen says all of its apps are open source. Developers get a documented API, TypeScript, Rust and Go SDKs, and a CLI that can run a local WebDAV or S3 server.
- Mobile camera upload
- The iOS and Android apps upload photos and videos from selected albums automatically, with optional compression, and can keep chosen files available offline.
Koofr
- Connected clouds and one search
- Paid plans connect Dropbox, Google Drive and OneDrive accounts so their files can be browsed and searched next to Koofr storage. The limit runs from 9 to 30 connections, depending on the tier.
- Two-way sync and network drive
- Desktop apps for Windows, macOS and Linux sync chosen folders in both directions and can map Koofr as a network drive. Storage can also be reached over WebDAV and with rclone.
- Koofr Vault
- An open source, client-side encrypted folder with zero-knowledge keys, included on every plan. It is used through a web app and iOS and Android apps, and is compatible with rclone.
- Sharing and receive links
- Files are shared with other Koofr users or through public links, and receive links collect files from anyone. Paid plans lift the 10-link caps and allow permanent links.
- Office for the web
- Paid accounts can create, view and edit Word, Excel and PowerPoint files in the browser, and edit shared documents together with other Koofr users in real time.
- No tracking, EU hosting
- Koofr states that it uses no third-party tracking tools, no ads and no cookies apart from the login cookie. Servers are in ISO 27001 certified data centers in Germany.
