StockVault - Offline Inventory Manager PWA

StockVault is an inventory management application built with HTML, CSS and vanilla JavaScript. Deploy the included files to a static host without a backend, database server or build step.

Products, categories, suppliers, stock movements and purchase orders are stored locally in the browser using IndexedDB. After the first load over HTTPS, the app can work offline and can be installed as a PWA on supported browsers.

The responsive interface includes light and dark themes, eight accent presets and nine languages, with RTL support for Arabic, Urdu and Persian.

This is a single-device application. Browser storage is not encrypted and may be lost if site data is cleared or the device is lost. Export regular JSON backups and keep a copy outside the device.StockVault — Offline-First Inventory Management PWA StockVault is a complete, premium inventory management application built with pure HTML5, CSS3, and vanilla JavaScript.
