Questions & Answers

As answered by people managing LeetCode and AR Button.

What makes your product unique?

AR Button's answer:

AR Button is the only augmented reality solution built entirely for print products that runs 100% in the browser. There is no app download required and no file upload needed. Everything works client-side using WebXR technology, which means zero server-side processing and full GDPR compliance. Users can preview posters, framed art, business cards, flyers and packaging in real size on any surface, directly through their phone's camera. The button is fully customizable in terms of colors, dimensions and styling, and it integrates into any website with a simple embed code or QR code.

Why should a person choose your product over its competitors?

AR Button's answer:

AR Button stands out because it requires no app installation from end users. Most AR competitors force customers to download a dedicated app, which creates friction and lowers engagement. With AR Button, everything runs directly in the mobile browser using WebXR. It is also fully client-side, so no images or data are uploaded to external servers. This makes it inherently GDPR-compliant and privacy-friendly. The setup is simple: just embed a code snippet or share a QR code. There is a free plan to get started, and paid plans scale based on AR preview volume. For businesses in print and packaging, AR Button is purpose-built for their exact use case, unlike generic AR platforms that try to cover everything.

How would you describe the primary audience of your product?

AR Button's answer:

The primary audience for AR Button includes online shops and e-commerce businesses that sell print products like posters, framed art, canvas prints, business cards, flyers and packaging. It is especially useful for print-on-demand services, art galleries with online stores, and packaging companies that want to let customers preview how a product will look in their real environment before buying. Marketing agencies working with physical print media also benefit from AR Button to create interactive campaigns. The tool is designed for businesses of all sizes, from small Etsy-style shops to larger retailers, who want to reduce return rates and increase customer confidence through realistic AR previews.

What's the story behind your product?

AR Button's answer:

AR Button was founded by Peter Podluczky in Austria with a clear mission: making augmented reality accessible for everyday businesses, especially those in the print and packaging industry. The idea came from the observation that while AR technology was advancing rapidly, most solutions were complex, expensive and required dedicated apps. Small and medium businesses selling physical print products had no practical way to offer AR previews to their customers. AR Button was built to change that by providing a simple, browser-based AR solution that any online shop can integrate in minutes. The product is developed and hosted entirely in the EU, with a strong focus on data privacy and GDPR compliance from day one.

Which are the primary technologies used for building your product?

AR Button's answer:

AR Button is built on modern web technologies with WebXR at its core. WebXR is the browser API that enables augmented reality experiences directly in mobile browsers without any plugins or app installs. The front-end rendering uses WebGL and Three.js for real-time 3D visualization. The AR button itself is a lightweight JavaScript widget that can be embedded into any website. On the back end, the platform runs on a standard web stack hosted on EU-based servers. The system supports multiple image formats including JPG, PNG, TIFF and PDF, and converts them on the client side for AR display. A REST API is available for automated product management and custom integrations.

Who are some of the biggest customers of your product?

AR Button's answer:

AR Button primarily serves small and medium-sized businesses in the print and e-commerce space. The customer base includes independent online art shops, print-on-demand providers, packaging companies and marketing agencies across Europe. As a focused niche product for browser-based AR previews, AR Button works with businesses that value privacy, simplicity and fast integration over enterprise-scale complexity. Specific customer names are not publicly disclosed, but the product is used across multiple industries where physical print products are sold online.
