HGDE Studio · Mannheim, Germany
Shopify apps built from running a real online store.
We run our own Shopify store, HalloGeschenk.de – and build the tools we wished we’d had there. First up: HGDE MatchGrid.

Our first release
HGDE MatchGrid
Image cards guide shoppers step by step to a matching product. With bundles, whole sets of real products go into the cart in one click – with a tiered discount that Shopify calculates at checkout.
- Product finder with image cards – no dead ends
- Bundles made from real products in your store
- Added through the theme editor, no code
- In English and German
The app is fully built and is being prepared for the Shopify App Store.
Where it all starts
HalloGeschenk.de
HalloGeschenk.de is our German Shopify store for personalised gifts and fun little presents.
- Photo gifts, including AI effects such as cartoon or pop art
- Engravings on jewellery, glasses and more
- Personalisation with a live preview
- Gift ideas ready to ship
Running it every day shows us where shoppers get stuck and what costs merchants time. That’s where our apps come from.

How we work
Small, lightweight, honest.
Built from practice
Every app starts with a problem we had in our own store – not on a whiteboard.
Light on your store
No heavy code in your theme. HGDE MatchGrid needs about 3 KB of JavaScript and 2 KB of CSS (gzip).
Privacy-minded
We store as little as possible. HGDE MatchGrid collects no data about store visitors and sets no cookies.
