Hey Product Hunt 👋 Many years ago I built an electronic parts catalog for European truck parts — gearboxes, axles, brakes. Click a diagram, find the part. It shipped, it worked, people used it every day. I always wanted to take that idea further: make it work for *anything*, not just truck parts, and put it in anyone's hands for free. This week I finally built it. **Electronic Catalog Maker** turns any photo or diagram into a clickable, searchable catalog. A few things that make it different: 🖱️ **Click a hotspot, see the row.** Any image — a schematic, a floor plan, a product photo — gets clickable points that link to a data table (name, SKU, specs, price, whatever you need). 📦 **One file, no backend.** A catalog is a single portable `.ecatm` file (it's SQLite under the hood). No server, no account, no install — everything runs in your browser. 🔌 **Embeddable anywhere.** `` is a Web Component you can drop into any site with one script tag. 🤝 **Real-time collaboration, self-hosted.** Click "Start collaboration," send the link, and edit the same catalog live with someone else — no account, no cloud service of mine in the middle. It runs on a tiny app you launch on your own machine. 🛒 **Sell straight from it.** Add a checkout URL to any row's data and a Buy button appears — works with pretty much any online store, and multiple items combine into one cart. 💻 **Install like a real app.** No app store needed — your browser offers "Install" and it becomes a real desktop app. It's free and open-source (MIT). Two live demos are linked below — try clicking around, takes under a minute, nothing to install. Would love to hear what you'd use this for, and any rough edges you hit — I'll be here all day answering everything. 🙏

One more thing I couldn't fit into the write-up above — real-time collaboration in action. Two people editing the same catalog live, self-hosted, no account, no cloud service of mine involved:

Happy to answer questions about how the sync works under the hood 🤝
