This project is a free, open source generator for digital business cards, also called vCards. It lets you create a contact card that others can save straight to their phone by scanning a QR code or tapping an NFC tag, without needing to install any app. Anyone who opens your card's link can download a .vcf file that adds your details directly to their contacts. The interface is described as modern and responsive, with dark mode support, and works well on any device. You can create a free account to save your card and come back later to edit it. There is also an admin dashboard for keeping track of users and the cards they have generated. If you want to keep your contact details private, you can protect a card with a PIN so only people you trust can download it. You do not have to run this yourself. The developer hosts a free version at vcard.everblue.work that anyone can use right away. If you prefer to run your own copy, the project is packaged as a Docker container with a lightweight SQLite database, so you do not need a separate database server. Setup involves cloning the repository, generating a secret key, setting an admin username and password, and starting the container with Docker Compose. Once running, the app is available on your own server, though the README recommends putting it behind a reverse proxy such as Nginx or Caddy so it can be served over HTTPS. Under the hood it is a Python project using the Flask web framework and Gunicorn to serve it, with a plain HTML, CSS, and JavaScript frontend, no separate framework required. The project is open source under the MIT license, and the author welcomes contributions, bug reports, and feature requests through the issues page.
