Open full demo Edit this example
Buy opens our demo store checkout, where every item costs $0.
Build your own: add an image → mark the details with hotspots → save the catalog file and open it in Viewer.
Put it on your own site: the demo above is the embeddable widget itself — one <script> tag and one <ecm-viewer> line put it on your page. See it on a sample store site → · How to embed →
Who it's for
Furniture and home goods
Shop the look: tap a piece in a room photo to open it with its details and a Buy button. Or lay out the whole range as a product grid. Open the demo →
Parts and equipment
Exploded views linked to part numbers, descriptions and a Buy button — the number on the diagram matches the row in the table. Open the demo →
Paid and members-only catalogs
Sell a guide or a course, or share some catalogs with everyone and keep others for the people you give the password to. One password per file — no accounts, no server; anyone who has the password can open it. You create the protected copy in the Editor. Open the demo (password: stool-2026) →
Teaching and learning
Explorable diagrams for lessons and class projects — no student accounts, no cloud. See the schools page →
Gyms and fitness
Pick a muscle group, find the machine, see how to set it up and print a workout — no app, no account. Open the demo →
Tests and self-check
Answer options sit on the picture — tap one and it turns green or red, with a running score. Try the demo →
The apps
Editor →
Build a catalog: place hotspots on an image, attach data to each.
Collaboration Server
Optional, self-hosted: edit a catalog live with someone else.
Catalog Server
Optional, self-hosted: share a folder of catalogs from your own computer, on your network or the internet.
Built around your catalog files
- Free, no subscription The apps are free and open source (MIT). No accounts, no plans.
-
Your catalog is one file
Images, hotspots and data live together in a single
.ecatmfile on your device. It goes nowhere unless you share it. - Photos and diagrams Put hotspots on any image — a room photo, a parts diagram, an anatomy chart — and link images together: tap the sofa in the room to open its close-up.
- Links to your own store Point items at any online store you already use. There's no marketplace or checkout of ours in between.
- Works offline after you first open it After you first open the apps on a computer, tablet or phone, they are cached in your browser and keep working without a connection.
- Live editing and catalog sharing, only if you want them Two optional apps you run yourself: the Collaboration Server for live editing together, and the Catalog Server for sharing a folder of catalogs on your network or the internet. Everything else works without them.
