I built a browser-first barcode toolkit for warehouse and labeling workflows

I started BarcodeOn because of a simple operational problem.

Sometimes a worker already has the correct code value, but needs a scannable barcode immediately on a phone, PDA, or desktop.

The first version focused on Code 128, but the project gradually expanded into a broader barcode toolkit.

BarcodeOn now supports:

  • Code 128
  • EAN-13
  • UPC-A
  • ITF-14 / GTIN-14
  • Code 39
  • GS1-128
  • Bulk barcode generation
  • Excel-style multi-cell paste
  • Check digit calculation and validation
  • Barcode scanning and validation
  • SVG export
  • Clean printing
  • PDA-friendly one-by-one navigation

One design decision I cared about from the beginning was keeping entered barcode values inside the browser rather than sending them to a server.

I also tried to make the tool work for real warehouse and inventory workflows, not just as a generic barcode image generator.

For example, you can paste multiple cells directly from Excel, generate the codes in bulk, and then move through them one by one on a PDA or phone.

BarcodeOn is free to use and does not require an account:

I’d especially appreciate feedback from developers or people working with logistics, inventory, retail, warehouse systems, or labeling workflows.

What would make a barcode tool more useful in your day-to-day work?
