--- title: Filen canonical: https://saasranked.com/software/filen/ category: Cloud Storage Services points: 59 rank: 3 of 10 facts_checked: 2026-10-08 --- # Filen End-to-end encrypted cloud storage from Germany with open-source apps and 10 GiB of free space. 59 points out of 100. #3 of 10 cloud storage services. Vendor: Filen Cloud Dienste UG. Website: https://filen.io/ - The free plan gives 10 GiB of storage [1]. - Filen says all files are zero-knowledge end-to-end encrypted, and all its apps are open source under AGPL-3.0 [2][8]. - Pro I gives 200 GiB for €19.99 a year; Pro III gives 2 TiB for €89.99 a year [1]. - Lifetime plans are not on sale; Filen says it removed them for an indefinite period [1]. - Desktop apps exist for Windows, macOS and Linux, and mobile apps for iOS and Android [4][5]. Verdict: Filen suits people who want end-to-end encryption on every file, open-source code and a cheap annual plan [1][2][8]. It has a network drive, sync modes and password-protected links [4][9][10].
