MapView: Server-Side Map Rendering for Rails

April 12, 2026

After an extensive development journey, MapView has arrived: a powerful API for generating map images directly from your Ruby server.

What is MapView?

MapView is a Ruby gem that enables you to render maps, routes, points, and polygons with zoom levels ranging from a global world view down to neighborhood-specific details. Everything is processed server-side, without JavaScript dependencies or expensive external API calls.

Built on ruby-libgd and libgd-gis, a robust architecture that delivers:

• ✅ Deterministic rendering (predictable results)
• ✅ Multiple map styles (OSM, Carto, Mapnik, etc.)
• ✅ Configurable resolutions (up to 4K)
• ✅ Full customization: legends, logos, watermarks
• ✅ GeoJSON support, routes, real-time alerts

Use Cases

Embedded in PDFs and Emails:

map = MapView.render(
  bbox: "argentina",
  basemap: :osm,
  geojson: routes_data,
  width: 800, height: 600
)
# Attach directly to PDFs or emails

Custom REST APIs: Create endpoints that generate maps on-demand, giving your users complete control over geographic data visualization.

Real-Time Dashboards: Update route visualizations, alerts, and points of interest as data arrives from your endpoints.

Logistics & Delivery Tracking: Generate route maps with multiple stops, travel times, and status indicators for customer communications.

Report Generation: Automate the creation of geographic reports with embedded maps, perfect for stakeholder presentations.

Sample GeoJSON to test:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [-58.3816, -34.6037]
      },
      "properties": {
        "name": "Buenos Aires",
        "description": "Capital of Argentina"
      }
    },
    {
      "type": "Feature",
      "geometry": {
        "type": "LineString",
        "coordinates": [[-58.3816, -34.6037], [-64.1833, -31.4167]]
      },
      "properties": {
        "name": "Route BA to Córdoba"
      }
    }
