Nobody is talking about this.
People are charging $50-$100 for custom city map posters on Etsy and printing them on demand.
A developer just open-sourced the entire workflow for free.
It's called TerraInk.
Type any city on Earth, customize every detail, and download a print-ready poster in minutes.
Everything is pulled live from OpenStreetMap roads, rivers, parks, building outlines, all of it.
You control the colors, the themes, the fonts, the layout, everything down to the last detail.
Export a high-resolution PNG and send it straight to a print shop.
No account to create. No subscription to pay. No checkout to click through.
The whole thing runs in your browser right now.
Self-host it with a single Docker command if you want it completely offline and yours.
Etsy sellers are making real money selling exactly this.
