The verdict: can you vibe code RoboForm?
Build a personal-use subset with a local SQLite vault and Next.js frontend, but keep paying if you need polished multi-platform native extensions and risk-free zero-knowledge sync.
Creating a personal-use password manager clone is a classic cryptographic and engineering challenge. While a web-based dashboard and local-first encryption vault can be put together in a few weeks using modern tooling, writing bulletproof browser extensions that safely inject fields across arbitrary shadow DOMs without triggering security policies is exceptionally tedious. Furthermore, implementing zero-knowledge key derivation correctly requires absolute discipline—any mistake in PBKDF2 parameters or IV management compromises your vault entirely.
Estimated effort: 2-4 weeks part-time

Build guide
01Project Scaffolding and Database Setup
Initialize a Next.js project with Tailwind CSS and configure Turso as the database backend.
Scaffold a new Next.js 16 project using TypeScript and Tailwind CSS v4. Initialize the project structure with App Router. Configure Drizzle ORM to connect to Turso. Create a database schema for users and encrypted_vaults, where the vaults table stores an encrypted blob string, a salt, and an initialization vector (IV) per user ID, ensuring the server never receives plaintext credentials. Add a basic health check API route to verify the database connection.02Client-Side Zero-Knowledge Cryptography Module
Implement browser-based PBKDF2 key derivation and AES-GCM encryption helpers using the native Web Crypto API.
Create a TypeScript cryptography utility module using the browser's native window.crypto.subtle API. Implement functions for: (1) generating a secure random salt; (2) deriving a 256-bit AES-GCM encryption key from a user's master password and salt using PBKDF2 with 100,000 iterations of SHA-256; (3) encrypting a JSON string of vault items into an encrypted ciphertext blob with a random IV; and (4) decrypting the ciphertext blob back into JSON using the master password and stored salt/IV. Ensure no plaintext keys or passwords ever leak outside local memory or get sent in API requests.03Authentication Integration
Set up user registration and session management using better-auth.
Integrate better-auth into the Next.js application to handle user registration, email/password login, and session cookies. Configure the auth schema to map directly onto the Turso database. Ensure that authentication only verifies account ownership and session tokens, leaving the decryption of vault items strictly to the client-side master password logic implemented in Step 2.04Vault Dashboard and Password Generator UI
Build the main dashboard interface for managing passwords, viewing items, and generating secure credentials.
Build a responsive dashboard UI using Tailwind CSS inside the Next.js App Router. Implement a Master Password unlock modal that prompts the user for their master password upon session start, deriving and caching the CryptoKey securely in session memory. Create components for viewing, searching, adding, and deleting vault items (logins, secure notes). Include a fully customizable password generator component supporting adjustable length, uppercase, lowercase, numbers, and symbols with live entropy scoring.05Encrypted Sync API and Polish
Implement server synchronization endpoints for saving and retrieving encrypted vault blobs.
Implement server-side API endpoints in Next.js to sync the client-side encrypted vault payload. The endpoints should securely accept authenticated requests containing the encrypted blob, salt, and IV, and store them in the Turso database without inspecting or decrypting the payload. Add error handling, loading states, and toast notifications for successful sync actions across devices.
