A truly exceptional file explorer
Navigate encrypted content through a polished interface with clean hierarchy, fast search, thoughtful spacing, and file management interactions that feel native on every platform.
Cross-platform auto-sync
Enjoy seamless cross-platform support with auto-sync. Changes are encrypted locally and synced automatically, so every device stays current.
Bring your own storage & 50GB
Leverage up to 50GB of free tier storage offered by providers like Backblaze B2 or Cloudflare R2, preventing single-vendor lock-in.
Bring your own key (BYOK)
You control the master key. Combined with decentralized storage, this ensures users completely own their encrypted data.
Objective data privacy superiority you can verify.
Standard cloud providers hold your keys and harvest your file data. FiFe is an open-source alternative built on absolute zero-knowledge principles.
Superior than standard AES-256
Data is encrypted before leaving the user device using modern cryptographic standards that are objectively superior than the AES-256 encryption which other service providers normally use.
No metadata stored
Unlike standard cloud storage solutions that track your activity, FiFe does not store file metadata like others do, ensuring your folder structures and file sizes remain completely private.
Advanced Tech Stack
Our architecture routes the domain directly through Cloudflare Workers and Hyperdrive connected to a Neon.tech PostgreSQL database. This eliminates the need for certificate pinning and Cloudflare channels, maximizing backend security.
Start syncing in three easy steps.
The flow is intentionally simple so the product feels approachable, even though the foundation is built for serious privacy.
