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.

Challenging codes

Challenging codes

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

Faded or damaged prints

Faded ink and damaged bars make barcodes difficult to read.

Uneven illumination

Uneven illumination, low light and reflections can be challenging.

Inverted codes

STRICH fully supports reading inverted codes (light print on dark background) for all types.

ZXing and QuaggaJS

ZXing and QuaggaJS often have issues reading more challenging codes. See how STRICH compares to free alternatives.

If you exceed the limit for two consecutive months, we will gently nudge you towards a higher subscription plan. We will not reject scans. You will have enough time to make a decision.

Do I get free updates?

STRICH is distributed in a subscription model. You are always entitled to the latest version, and all features in it.

Does STRICH support Angular/Vue/React/SvelteKit?

Why should I pay when there are free alternatives?

If a free alternative like ZXing or QuaggaJS works for you, then you may not need STRICH. If you prefer a maintained, professionally supported and high-performing scanning solution, STRICH might be the answer. See how STRICH compares to free alternatives.
