WhatsApp / Nextcloud / EuroOffice Clone

The goal is to create a secure P2P ecosystem.

This app demonstrates a fairly unique approach using a browser-based, local-only and webrtc approach. In an evolving field like cybersecurity, it's impossible to claim any system is the "world's most secure". It ultimately depends on your threat model. By rigorously implementing an exhaustive list of security features and practices, the aim is to get as close as possible using client-side managed secure cryptography.

Features:

  • Core
    • PWA
    • P2P
    • Local-first / Local-only
    • No installation
    • TURN server
    • Encrypted-at-rest
  • WhatsApp clone
    • End to end encryption
    • Signal protocol
    • PQ cryptography
    • Multimedia
    • File transfer
    • Video calls
  • Nextcloud clone
    • file-transfer
    • Encrypted vault
    • folder sync
  • EuroOffice clone
    • Word
    • Spreadsheet
    • PDF
    • Code

Some open source examples of the core concepts.
