# Filen

> End-to-end encrypted cloud storage from Germany with open source apps

Filen is a cloud storage service from Germany in which every file is encrypted on the device before upload, so the company cannot read what is stored. Its apps for the web, Windows, macOS, Linux, iOS and Android are open source and add folder sync, a network drive, encrypted notes and chats. Every account starts with 10 GiB free, and paid plans from 100 GiB to 10 TiB can be stacked on one account.

## Key features

- **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.

## Good for

- People who want every file end-to-end encrypted, on the free plan too
- Users who prefer open source clients and storage hosted in Germany
- Developers and sysadmins who want a CLI, SDKs and a documented API
- Linux users: the desktop app ships as .deb, .rpm and AppImage

## Worth knowing

- 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.
