Swiish is an open-source, self-hostable platform for creating and sharing digital business cards. It lets you build customizable cards with contact details, generate QR codes (simple links or full vCards), share them via unique URLs, and enable recipients to save the info directly to their phones, with PWA support for offline access and an admin dashboard for management. This app helps me by giving me a polished, always-up-to-date digital business card that I can share instantly through a simple link or QR code, letting people save my contact details straight to their phones. It supports me in my journey by making networking effortless at events or online, keeping my professional presence under my full control on a self-hosted platform, and allowing me to customize how and when my information is revealed so I can connect more effectively without relying on third-party services. In this step by step guide I will show you how to install SwiishĀ on your Synology NAS using Docker & Dockhand.
