Why local barcode generators matter (Network-tab privacy)

Inventory CSVs and product codes are operationally sensitive. Upload-based generators ask you to trust a third-party server with every SKU. A local tool lets you refuse that trade.

Prove it in DevTools

1. Open DevTools → Network, clear the log.
2. Paste values or a CSV and generate the ZIP.
3. You should see static assets (HTML/CSS/JS) only — not a POST of your CSV body.

LocalBarcode vendors JsBarcode and JSZip under /assets/vendor/ so generation does not call a CDN at runtime (CSP script-src 'self').

Not WifiSignQR

WifiSignQR is for Wi‑Fi join and vCard QR codes. LocalBarcode is for linear barcodes (Code128 / EAN). Same privacy philosophy, different symbology and SEO intent — keep them separate products.
