FiFe - Your private Files Ferry

https://fife.jeero.one

An open-source, cloud storage backup service built with zero-trust architecture. Your data is encrypted locally before it ever leaves your device.

🛡️ Why FiFe?

Traditional cloud storage providers hold the keys to your data. FiFe shifts the control back to you. By combining Bring Your Own Storage (BYOS) with strict Client-Side Encryption, FiFe ensures that nobody—not even the server hosting the app—can read your files.

✨ Key Features

• 🔒 Zero-Knowledge Client-Side Encryption: Files are encrypted entirely on your device using libsodium before uploading. The server only stores encrypted key ciphers and nonces.
• ☁️ Bring Your Own Storage: Connect your own object storage buckets. Currently supports Backblaze B2, Cloudflare R2, ORACLE and IDrive E2.
• 📂 Preserves Folder Structure: Back up entire directories without losing your organizational hierarchy.
• ⚡ Smart Duplicate Detection: Computes hashes locally on-demand to detect duplicate files, saving your bandwidth and storage space.
• 🚀 Direct-to-Cloud Uploads: Uploads bypass the backend completely, utilizing secure, pre-signed URLs directly to the storage provider.
• 🚫 Zero Tracking: Built with strict privacy in mind. Absolutely no third-party analytics or data harvesting.

🏗️ Architecture & Tech Stack

FiFe is split into a robust cross-platform client and an edge-optimized server:

Frontend / Client App

• Built with Flutter for Android, iOS, OSX, and Linux (AppImages).
• Background task synchronization using Workmanager.
• Local metadata management via SQLite.

Backend / API

• Built with SvelteKit and deployed on Cloudflare Workers.
• Database: Neon Postgres using Drizzle ORM.
• Uses Cloudflare Hyperdrive for accelerated database connections.
• Authentication handled securely via Email OTP (Neon.tech).

🚀 Getting Started

Prerequisites

• Flutter SDK (latest stable)
• Node.js & npm (for backend development)
• A Neon Postgres database URL
• Cloudflare Wrangler CLI
