city-map-platform is a Next.js app for publishing city guides. Its homepage headline is “Maps that feel like posters, not dashboards.” Each city is a pack: a map outline, a color palette, landmark illustrations, and a set of category pages. The page and agent routes are generic and keyed by city, so a new city is a new pack rather than a new set of pages, and a pack can be served from its own domain.
The Mumbai pack
Mumbai is the only pack in the source. It is written for people visiting Devcon 8 in Mumbai in November 2026 and has three categories: an overview, food, and hotels. The map marks 15 places, from the Devcon venue to the Gateway of India, Chhatrapati Shivaji Maharaj Terminus, Marine Drive, and the Elephanta Caves.
The map is drawn on a canvas. Each category’s text is set inside the outline of the city and flows around the landmark illustrations, using a vendored copy of the Pretext text-layout library.
Briefs for agents
Every city and category also has an /agent route that returns plain Markdown. The Mumbai brief names its audience (international Devcon visitors and first-time visitors), its goals (make the city legible in about two minutes, and explain why a landmark matters rather than only what it is), and its tone, which avoids tourism-brochure clichés. An agent helping with a trip can read the guide’s intent directly instead of parsing a canvas.
What it showed
- A map can be an editorial object with a point of view, not only a data display.
- The same guide can ship twice: as a visual page for people and as a Markdown brief for agents.
- Keeping city content in packs separates the guide from the rendering code.
What it sits beside
- Atlas Obscura city guides.
- Devcon and conference travel microsites.
- Google My Maps and Felt.
