Amazon S3 vs Filen

Amazon S3 is an object storage service for storing, managing, analyzing, and protecting data used by data lakes, cloud-native applications, and mobile apps. Capacity adjusts as objects are added or removed, without requiring storage to be provisioned in advance. Storage classes cover frequent access, infrequent access, and archiving. Versioning preserves object versions, while Replication can copy objects to buckets in the same or different AWS Regions. Amazon Athena and Redshift Spectrum can query S3 data in place with SQL; S3 Vectors adds vector storage and querying, including integration with Amazon Bedrock Knowledge Bases. Security controls include encryption for uploads, Block Public Access, and Object Lock for customer-defined retention periods. AWS documents access through its Management Console, CLI, SDKs, and REST API. S3 is listed for Android, API, iOS, Linux, macOS, web, and Windows. A Free Tier is available. Pricing is usage-based, with charges varying across storage, requests, retrieval, transfer, and other features. Some archived objects have minimum storage durations of 90 or 180 days, and early deletion incurs a prorated charge.

Filen is a cloud storage service that encrypts data on the client before storage, using zero-knowledge, end-to-end encryption. It supports syncing, network-drive access with Smart Sync and five sync modes across Windows, macOS, Linux, iOS, Android and the web. Mobile apps include encrypted camera uploads, offline files, notes, chats and notifications. Encrypted notes support rich text, code, Markdown and checklists, while chats are end-to-end encrypted. Developers can use the documented API, command-line interface and TypeScript, Rust and Go SDKs. The desktop client and CLI can run local WebDAV and S3-compatible mirror servers. Filen says its apps are open source under AGPL v3 and that its headquarters and servers are in Germany. The free account includes 10GB storage. Paid monthly plans start with Pro I at €1.99 a month for 200 GiB; higher tiers offer 500 GiB, 2 TiB or 10 TiB. Filen says data in free accounts is deleted after three months of inactivity, with reminder emails beforehand.
