Premium Bring-Your-Own-Storage E2EE Drive Client

A polished desktop and mobile client that connects to any 'dumb' storage (S3, SFTP, WebDAV) and provides a modern cloud-drive experience. It handles all encryption locally before transmission, giving users strict zero-knowledge security without sacrificing UI quality or relying on bloated server software.

Pourquoi c'est important

You care deeply about the privacy of your files, so you refuse to trust corporate cloud providers. You try hosting your own smart server, but it's packed with bloated features you don't need, and the encryption feels like a fragile afterthought. To get true security, you resort to chaining together local encryption tools with basic background sync protocols. This works, but it feels incredibly clunky. You lose the ability to easily preview photos, the mobile experience is disjointed, and the premium feel of a modern drive app is completely gone. You just want a beautiful, seamless app that encrypts your files invisibly and saves them to a simple storage backend.

  • · Conçu pour Privacy-conscious professionals, developers, and prosumers who want absolute control over their data without suffering through poor user interfaces..
  • · Monétisation la plus probable : one-time lifetime license per major version, or low annual subscription.

Périmètre MVP · 1–2 semaines

Semaine 1
  • Initialize cross-platform project using Rust and Tauri.
  • Implement AES-GCM encryption/decryption logic in Rust core.
  • Build connection module for a single standard storage backend (e.g., standard S3).
  • Create basic frontend file explorer interface in React.
  • Wire up upload/download functions so files are encrypted locally before hitting S3.
Semaine 2
  • Implement local SQLite database to cache directory structures and metadata.
  • Add virtual folder navigation in the UI to browse without downloading everything.
  • Build a local thumbnail generator that runs on decrypted images in memory.
  • Implement robust error handling and sync retry logic.
  • Deploy landing page explaining the architecture and open pre-orders.
Fonctions MVP: Agnostic storage backend support (S3, SFTP, WebDAV) · On-the-fly client-side AES-256-GCM encryption · Virtual drive mounting (access files without downloading entire vaults) · Local thumbnail generation for secure media browsing · Mobile companion app for accessing encrypted vaults on the go

Différenciation

Solutions existantes
NextcloudSeafileCopyparty
Notre angle
A unified, premium desktop and mobile client that brings a seamless 'cloud drive' interface to user-provided 'dumb' storage (S3, WebDAV) using strictly local client-side encryption.

Pourquoi cela pourrait échouer

Auto-contre-argument — le signal de confiance le plus important

  1. 1Building a virtual filesystem that integrates natively with OS file explorers is notoriously difficult and bug-prone.
  2. 2Existing free tools (like Cryptomator) are heavily entrenched, making it hard to convince users to pay for a UX upgrade.
  3. 3Sync state management across multiple offline devices may lead to corrupted encrypted blobs.

Résumé des preuves

Comment l'IA a synthétisé cet aperçu — pas de citations textuelles

Multiple community members emphasized that true zero-knowledge privacy requires separating smart software from dumb storage. Around six commenters discussed relying on complex combinations of local encryption and basic sync protocols to protect their data, while expressing frustration over the loss of premium features like web previews. The consensus indicates a strong desire for a solution that bridges the gap between paranoid security practices and seamless user experience.
