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

Description and use

A modern, mobile‑friendly UI overhaul for a self‑hosted data manager using Vue.js and Vite, keeping all data on‑premises.

Problem

Users need a single 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 made the application mobile‑friendly while keeping the system fully self‑hosted.

Workflow

• 1. Replace jQuery with Vue.js for reactive UI
• 2. Split frontend into a separate project
• 3. Migrate build system to Vite
• 4. Add TypeScript support
• 5. Update PHP dependencies as needed
• 6. Deploy self‑hosted instance

Evidence

dropped jQuery in favor of Vue.js

Source

frontend is now a standalone project, with the original tool serving as backend

added TypeScript support

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