VoucherVault is a self-hosted Django web application for digitally managing vouchers, gift cards, coupons, and loyalty cards. It provides a full CRUD interface with features like barcode/QR code scanning, expiry notifications via Apprise, multi-currency support via Fixer.io, offline-first capabilities (service worker + IndexedDB sync), OIDC authentication, item sharing between users, and a PWA manifest for mobile installation. The architecture is a monolithic Django app with Celery for background tasks (expiry checks), Redis as a message broker, and optional PostgreSQL or SQLite databases. The frontend uses the NiceAdmin Bootstrap template with custom dark mode and charting via ECharts. The codebase is well-organized with clear separation of concerns (models, views, forms, templates, static assets) and includes internationalization for English, German, French, and Italian. While the application is feature-rich and actively maintained, it lacks automated tests and has some code duplication in templates, which limits its quality score.
