TerraInk turns map data into poster art

ANNOUNCEMENT PRODUCT GITHUB PRODUCT HUNT YOUTUBE

TerraInk is an open-source map-poster engine that lets people search for a location and turn OpenStreetMap data into stylized, print-ready artwork. The project emphasizes a creative workflow over technical cartography, with theme presets, custom palettes, typography controls, layer-level styling, and high-resolution PNG export. It is built with Bun, React, and TypeScript, and the README frames it as a JavaScript reimplementation inspired by MapToPoster.

// ANALYSIS

Big-picture, this feels less like a GIS tool and more like a “Canva for city maps” with enough map-stack depth to stay useful.

–The strongest hook is customization: themes, fonts, colors, and layer styling make the output feel intentionally designed rather than generic.
–OpenStreetMap + MapLibre + OpenFreeMap is a practical stack, and the PNG export makes the project immediately tangible for posters and gifts.
–The main limitation is scope: it’s still in development, so polish, performance, and template breadth will determine whether it becomes a real workflow tool or mostly a showcase.
