Open Source ChromeOS QR Code Generators

Decimen Optical Transfer is a browser-based proof of concept for moving files between devices through animated QR codes. A sending screen continuously displays encoded frames while a receiving camera captures enough of them to reconstruct the original payload. The system requires no direct network path, pairing process, native application, or permission beyond camera access. Fountain coding makes the stream tolerant of missed, blurred, duplicated, and out-of-order frames without requesting retransmission. Each QR frame includes session and file metadata, allowing a receiver to join an active stream or reset when a new session begins. QR decoding runs through zxing-cpp compiled to WebAssembly and uses workers to process camera frames efficiently. Configurable settings control payload size, transmission speed, QR density, capture resolution, and worker count, while a final hash verifies the recovered file.

jquery-qrcode is a small jQuery plugin for generating QR codes directly inside the browser. It lets developers add QR code output to a webpage without calling an external service or downloading a remote image. The plugin is designed to be lightweight, with a minified and compressed footprint of less than 4 KB. Its basic usage is simple: include the script, create a container element, and call the QR code method with text or options. Developers can configure dimensions such as width and height when generating a code. It is best suited for older jQuery-based sites, simple web utilities, landing pages, and legacy projects that need fast client-side QR generation.

QRMAN an open source Url Shortener and QR Code generator with excellent features. Create, Manage, track Qr codes. Excellent statistics for every QR codes.

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)
