Why barcode scanning in web apps? Moving your scanning workflows to web apps offers unique advantages over native apps.

No App Store required

No need to worry about App Stores and the headaches they bring. Host your web app anywhere you like, without platform risk.

Easy distribution

Distribute your app by sharing a link or a QR code. Web apps are always up-to-date.

Decrease development costs

Write your app once for the web instead of relying on expensive iOS/Android development. Avoid duplicating efforts and invest in a single code base instead.

Counter app fatigue

Don't force users to install apps they seldom need. App fatigue is real and it is unlikely you need a native app, especially for business apps.

Native-like experience

Progressive Web Apps (PWA) allow installing a web app on the user's home screen, increasing engagement and retention while offering advanced capabilities like offline operation and push notifications.

Built for the web STRICH is built from the ground up using modern web technology.

Standards-based

STRICH leverages modern JavaScript and web standards such as WebGL and WebAssembly for powerful image processing.

Broad compatibility

Works in all major browsers on Android and iOS, on both high-end and budget devices. Easy to integrate into all modern web frameworks.

Developer-friendly

Available on NPM with zero third-party dependencies. Single JavaScript file with TypeScript bindings and embedded WASM.

Continuously developed

Tracks emerging web standards so you don't have to. We are always working on optimizing the scanning experience.

1D and 2D Barcode Scanning STRICH supports a wide range of 1D and 2D barcodes, and we are always working on more. Check the list of supported barcode types.

1D symbologies

Code 128, EAN, UPC, Code 39, Code 93, ITF, Databar, Codabar.

2D symbologies

QR Code, Data Matrix, Aztec Code. PDF417 is coming soon.

On-device barcode detection

All image processing happens on the device in real-time by leveraging the power of modern web technologies.

Built-in scanning UI

Comes with a proven, built-in UI, so you don't have to build one yourself. Includes common components such as targeting overlay, camera selector, flashlight, tap-to-focus, etc.

Challenging codes Real-life barcodes are often difficult to read. STRICH uses advanced image processing to improve read rates over simpler solutions.
