WOLS (WeMush Open Labeling Standard) is fully open source under MIT license. The specification is public and free to implement.
Export all your data at any time in standard formats: JSON, CSV, or WOLS QR codes. No lock-in, no export fees.
Official libraries in JavaScript/TypeScript and Python let anyone read WOLS data. Your exported QR codes work forever.
All specifications and reference implementations are on GitHub. They can't disappear even if WeMush does.
Smart business owners consider what happens if a vendor goes away. With WeMush, you're protected.
When a SaaS company with proprietary data formats shuts down, customers often lose years of valuable data. Even with exports, undocumented formats become unreadable.
Anyone can implement a reader without our permission
Your printed labels contain the data—no server needed to read them
Production-ready code to read your data in multiple languages
