The verdict: can you vibe code MEGA?
Keep paying for MEGA; attempting a solo clone is a waste of months because you cannot realistically replicate zero-knowledge client-side encryption pipelines, cross-platform file sync daemons, and petabyte object storage infrastructure alone.
MEGA is an expansive multi-product privacy suite built over 13 years by a large engineering organization. Even if you drastically scope down to a personal web-based file vault, building a truly zero-knowledge file storage app requires implementing cryptographic key derivation, chunk-level streaming encryption, and robust file chunking in the browser without exposing plaintext. Furthermore, building a background sync client (`MEGAsync`) that listens to native OS filesystem events (FSEvents, inotify) and syncs reliably across Windows, macOS, and Linux is a massive systems programming undertaking in C++ or Rust. AI coding agents will generate clean UI components and basic Node.js upload routes, but they will completely fail at orchestrating complex cryptographic zero-knowledge metadata trees and high-performance sync engines.
Estimated effort: 6+ months of full-time work
What you can't replicate
- Zero-knowledge security guarantees across millions of shared files without formal security audits
- Cross-platform native sync background daemons for Windows, macOS, and Linux
- Petabyte-scale object storage infrastructure and global bandwidth delivery networks
- Bundled multi-product ecosystem (VPN node networks, password manager vaults, WebRTC SFU meeting servers)

The hard parts of vibe coding MEGA
- Implementing secure client-side cryptographic primitives (AES-GCM, key derivation) without leaking plaintext metadata or keys
- Building a native background file sync client that monitors filesystem events across OS platforms and handles delta uploads
- Managing petabytes of encrypted blob storage and high outbound egress bandwidth without prohibitive cloud bills
- Orchestrating multi-product integrations (VPN tunnels, password manager, WebRTC chat) into a single cohesive zero-knowledge architecture

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js project with Tailwind CSS, configure Turso SQLite connection for storing encrypted file metadata, user accounts, and share tokens, and set up better-auth.
Scaffold a new Next.js 16 application using TypeScript, Tailwind CSS, and App Router. Configure Drizzle ORM connected to Turso SQLite. Create database tables for users (id, email, passwordHash, salt), files (id, userId, parentId, name, encryptedSize, storageKey, mimeType, createdAt), and shared_links (id, fileId, token, passwordHash, expiresAt). Implement better-auth with email and password authentication, ensuring that user passwords are never stored in plaintext and generate a secure salt during registration.02Client-Side Zero-Knowledge Encryption Engine
Implement browser-side cryptographic helpers using the Web Crypto API (SubtleCrypto) to derive file encryption keys locally from user master passwords before any upload occurs.
Create a TypeScript cryptographic utility module using the browser's native Web Crypto API (`window.crypto.subtle`). Implement PBKDF2 key derivation from the user's master password and salt to generate a master key handle. Write functions to generate a random 256-bit AES-GCM key per file, encrypt file ArrayBuffers client-side into encrypted blobs, and decrypt blobs back upon download. Ensure private keys and master keys never leave client memory or get transmitted to the server.03Encrypted Cloud Storage Vault UI & Upload Pipeline
Build the core file manager interface allowing users to create folders, navigate directory trees, and stream encrypted chunks directly to Backblaze B2 object storage.
Build a responsive Next.js dashboard mimicking a secure cloud storage file manager with sidebar navigation, breadcrumbs, grid/list view toggles, and folder tree management. Implement a drag-and-drop file upload zone that intercepts selected files, triggers the client-side encryption utility from Step 2, uploads the resulting encrypted ciphertext blobs via presigned S3 URLs to Backblaze B2, and saves the file metadata record to Turso via server actions. Include progress bars for active uploads and downloads.04Secure File Sharing & Link Permissions
Implement secure granular link generation with optional password protection and expiration dates for sharing files with external users.
Add a 'Share' modal component for files and folders in the vault. When a user creates a link, generate a cryptographically secure token and optional password hash stored in the `shared_links` table. Implement a public download route (`/share/[token]`) that prompts for the optional password, decrypts the sharing key client-side using the derived token key, and streams the decrypted file directly to the browser recipient without requiring them to have a logged-in account.05Desktop Sync Shell with Tauri
Package the frontend application into a native desktop wrapper using Tauri to enable local folder synchronization and file system monitoring.
Initialize a Tauri v2 wrapper around the Next.js frontend to build a native desktop application for macOS and Windows. Implement a Rust background service using the `notify` crate to watch a designated local sync folder for file creation, modification, and deletion events. Build an IPC bridge that automatically triggers encrypted chunk uploads to the backend storage when local files change, mirroring the core functionality of a personal sync daemon.

Vibe code MEGA: FAQ
- Can you vibe code MEGA yourself?
