Try barKoder before you write any code. Install the free barKoder demo app on iOS or Android, open a web demo in your browser, or clone an open-source sample app for Flutter, React Native, Capacitor, Cordova, .NET MAUI, NativeScript, Android or the web.
Every demo on this page runs the same barKoder scanning engine that ships in the SDK. Product owners can test real barcodes in minutes with the store app or a browser. Developers can open a sample app in the framework they already use and see how the SDK is wired into a working project.
Install the free barKoder demo app, or open the web demo, and scan your own barcodes before you integrate the SDK.
iPhone and iPad
Scan with your camera, or point it at the QR code to open the App Store.
Android phones and tablets
Scan with your camera, or point it at the QR code to open Google Play.
Any modern browser
Runs the Web SDK in your browser, on desktop or mobile, with nothing to install.
The web demos run the barKoder Web SDK in WebAssembly. Your browser asks for camera access, and decoding happens on the page.
To add the same scanner to your own web app, follow the Web SDK installation guide or read about the Web Barcode Scanner SDK.
Scan all barcodes, pick a barcode type first, or scan an image file. Reads EAN/UPC, Code 128, Code 39, QR, Data Matrix, PDF417, Aztec, DotCode, DPM and VIN.
Open the web barcode demo →A React app built on the barKoder Web SDK that scans 1D and 2D barcodes client-side. Its source is the react-wasm-demo repository below.
Open the ReactJS web demo →Reads the machine-readable zone of passports (TD3), ID cards (TD1 and TD2) and visas (MRV-A and MRV-B), with check digits. Scan with the camera or pick a photo of the page.
Open the web MRZ demo →Test with known samples. Print or display the testing sheet and scan each 1D and 2D barcode with the demo app. The data sheet summarizes the SDK for your team.
Barcode Scanner by barKoder is free, with no ads and no in-app purchases. It reads barcodes and MRZ from the camera or from image files, and it is a demo of what the SDK can do. It also works as a standalone scanner, with exports to CSV or a webhook.
MatrixSight reads QR and Data Matrix codes that are missing key elements. Segment Decoding reads deformed or misshapen 1D barcodes. DeBlur reads severely blurred EAN and UPC codes.
How MatrixSight reads damaged codes →Batch MultiScan reads several barcodes from a single image. The AR modes highlight each barcode on screen in real time, show its result and let you choose which of many barcodes to scan.
See Batch MultiScan →LineSight reads PDF417 barcodes without start and stop patterns, row indicators or whole data columns. The app parses US and South African driver's licenses and GS1 barcodes, and reads the MRZ on passports, ID cards and visas.
See the MRZ scanner →DPM mode reads Data Matrix codes and QR codes engraved by Direct Part Marking. VIN mode reads the barcodes that carry Vehicle Identification Numbers. A DotCode template is built in.
See DPM scanning →Export scans to a .csv file, or turn on the webhook to POST each scan to your server. A secret word signs every request with a hash your server can check. Optional confirmation feedback shows your server's reply in the app.
To type each scan into a text field in another app instead, use barKoder Keyboard on iPhone, iPad or Android.
Supported devices: iPhone and iPad (iOS 15 or later), Macs with macOS 13 or later, Apple Vision, and Android phones and tablets.
Set up the demo app webhookClone a sample app in the framework you build with. Each repository below is maintained by barKoder in the barKoderSDK GitHub organization and was updated in 2026.
Each full demo app is a working application built with one framework and the official barKoder plugin. The Flutter, React Native and .NET MAUI apps include the whole scanner UI flow (camera lifecycle, permissions, configuration and result handling) and let you test all supported 1D and 2D symbologies, AR overlays, DPM, VIN, MRZ and VIN OCR, Segment Decoding, MatrixSight, PDF417-LineSight, DeBlur and Batch MultiScan. Each README shows how to add the plugin to your own project.
