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.

An easy-to-use PHP QrCode generator with first-party support for Laravel.

This is a plugin to KeePass <http://www.KeePass.info> to easily create the two-factor authentication parameters used by the KeePass placeholders {HMACOTP} and {TIMEOTP} from QR codes shown on screen.

This is yet another QR code reader. It grabs code from a screen, decodes it and copies content into clipboard. Decoded text can be formated before being copied, so it can be easily pasted to i.e. spreadsheet application.

SlowQR allows to scan QR codes from images. Some manual interaction for distorted codes is possible. Due to missing hardware-accelerated drawing support, automatic recognition may be slow, hence the name. New features: - creation/editing of QR codes. - support of images with perspective - optional experimental offscreen hardware acceleration (via openGL 2-FBOs)

Applications of Quick Response (QR) codes enable rich context interaction through creation of links between physical objects and internet resources. In spite of the widespread use of this kind of barcode, applications for visually impaired people and robots are not common because existing decoders assume that the symbol is properly framed during image acquisition. This project implements a two-stage component-based approach to perform accurate detection of QR code symbols in arbitrarily acquired images. In the first stage a cascade classifier to detect parts of the symbol is trained using the rapid object detection framework proposed by Viola-Jones. In the second stage, detected patterns are aggregated in order to evaluate if they are spatially arranged in a way that is geometrically consistent with the components of a QR code symbol. OpenCV 2.2+ is required.
