A developer has launched a new open-source project called QRScanner. This tool aims to provide a free, fast, and privacy-focused alternative to existing online QR code scanners. Many online tools are often behind paywalls, contain ads, or require app downloads. QRScanner offers a clean user interface with a choice of dark or light themes. It is built using HTML5, CSS3, and vanilla JavaScript for optimal browser performance. The project is hosted on Netlify and features a privacy-first approach, processing all data locally on the user's device. Key functionalities include scanning QR codes directly from a camera or uploaded images. It also allows users to generate custom QR codes for WiFi, WhatsApp, text, and URLs. The developer gained insights into browser camera permissions and image scanning optimization during its creation. Feedback on the UI, performance, and suggested features is welcomed by the developer.
