Show HN: I redesigned my self-hosted data manager's UI (4k stars, v2)

Description and use

Users needed a unified, self‑hosted platform to manage passwords, notes, files, finances, contacts, and health data without cloud services. In v2.0 the UI was rewritten with Vue.js, TypeScript, and Vite, and the frontend became a standalone project decoupled from the PHP/Symfony backend.

Problem

Users needed a unified, self‑hosted platform to manage passwords, notes, files, finances, contacts, and health data without relying on cloud services.

Outcome

The redesign modernized the UI, improved performance, and separated concerns between frontend and backend, while maintaining a self‑hosted, privacy‑focused architecture.

Workflow

• 1. Replace jQuery with Vue.js components.
• 2. Migrate frontend to a standalone project using Vite.
• 3. Add TypeScript support for type safety.
• 4. Refactor UI for mobile friendliness.
• 5. Keep PHP/Symfony backend for business logic.
• 6. Plan future upgrades of PHP and Symfony dependencies.

Backend is still PHP/Symfony based — it’s a bit behind with dependencies since most of my time went into features rather than upkeep.
