Six browser-based tools for barcode scanners, label printers and Android devices. No install, no sign-up, no admin rights — open a page and start working. Wherever it matters, the work runs in your browser, so nothing is uploaded to a server.

Configuring scanners and printers
Online Scanner Configurator — Open the configurator →
Change symbologies, prefixes and suffixes, timing, keyboard layout and more, straight from the browser over WebUSB. There is no configuration application to install and no administrator account required, so it works on a locked-down customer laptop.
Scanner Config-Code Tool — Open the code tool →
Tick the settings you want, and the page draws the matching configuration barcodes. Scan them to apply the settings — useful on a production line or during a service call, when there is no PC within reach.
Printer Command Preview — Open the preview tool →
Compose a label-printing command and preview exactly what it will produce before it reaches the printer. Test layouts, fonts and fields without wasting a single label.
Reading text and checking quality
Online OCR Tool — Open the OCR tool →
Run OCR on an image in your browser and get editable text back. Handy for pulling data out of a photo of a label or a screen, without sending the file anywhere.
Barcode Grading Tool — Open the grading tool →
Upload an image of a barcode and get a print-quality grade to ISO/IEC 15416 (1D) / 15415 (2D), with a readable report. Catch a degrading print head before a whole run is wasted. Also available as an offline engine with an API — see Pricing.
Working with Android devices
Android ADB Debug Tool — Open AI-ADB →
A complete ADB console that runs in the browser. Browse files, install and uninstall apps, watch a live logcat and mirror the screen — all over the USB cable. No drivers, no Python, no install on the device or the host. Your data never leaves the cable.
Requirements and limits
- A Chromium-based browser (Chrome or Edge) for the WebUSB and USB tools.
- The scanner tools need the device connected by USB; the OCR and grading tools work on uploaded images.
- The OCR and grading tools are currently in Chinese while we finish the English build — see the note below.
TIP
Tools are in transition to English. Our online tools still show Chinese interface text while we complete the English build, landing over the next few weeks. Need an English or tailored version now? Tell us what you need: sales@happylab.me.
