QRCodeSDK is an MIT-licensed project created and maintained by Dafnik within the QRCodeSDK repository.
The library’s matrix-calculation foundation traces back to LostInBrittany/qr-esm, which itself draws from Kang Seonghoon’s qr.js.
Additional recognition goes to soldair/node-qrcode, published as qrcode,
for driving broader progress in the JavaScript QR ecosystem.
For validation, QRCodeSDK relies on qrcode and qrcode-generator strictly as benchmarking baselines and correctness references.
These credits reflect historical lineage and testing standards rather than runtime requirements. QRCodeSDK carries zero runtime dependencies on any credited package.
