Open Source QR Code Scanners

Open QR Code is an open-source cross-platform application developed using Flutter as main framework used to build the application, in common C, C++, Dart, Skia (a 2D rendering engine), and Impeller (the default rendering engine on iOS), Java, Kotlin. Open QR Code allows users to generate and scan QR codes effortlessly. The app is available on Android, Windows, and the Web. Users can generate QR codes from any text input, save them to their gallery, share them directly from the app, and scan QR codes to retrieve encoded information. Whether you're on Android, Windows, or the Web, you can create and share QR codes or scan them with a single click.

Mini QR is a web app focused on making QR codes feel friendly and design-forward, combining a polished QR generator with a built-in scanner so you can both create and decode codes in the same place. It emphasizes customization so the QR you generate can match a brand, event theme, or personal style, including color and styling controls, framed layouts with labels, and the ability to add a logo image. Because QR reliability matters as much as looks, it exposes practical settings like error correction levels so you can balance data density with scannability, especially when adding a logo or encoding larger payloads. The scanning side supports camera-based scanning and image uploads, and it recognizes common QR content types such as URLs, emails, phone numbers, SMS messages, Wi-Fi credentials, and other structured payloads so the next action is obvious. It also supports workflows for producing many codes at once by importing CSV data and exporting batches.

QPyDesk is a code editor, and real-time QR code generator for QPython. It is a Python code editor with syntax highlighting that also generates the QR code that represents said code in real time. This application also allows you to print the generated QR code to distribute the created application. However, because QR codes have a limited storage capacity, if the code is very long, QPyDesk creates a QR code that is only valid while the application is running, that is, the QR code generated in this case is useless for distribute the application, but it is still useful to check the operation of the script while it is encoded from the computer. When these circumstances occur, QPyDesk notifies the user and disables the print button. QPyDesk gives dynamism during the development of applications for QPython / Android, since it takes advantage of the QPython QR code reader to work comfortably from the computer for the android device.
