Some data makes more sense on a map.
Real estate listings, delivery tracking, field service dispatch, store locators — when data has a geographic dimension, a map is often the right UI. Choosing the right mapping library, handling location data, and building performant map interactions requires specific technical knowledge.
Application that needs to display geographic data on a map — either as a core feature or as an enhancement to an existing list/table view
Map library options and trade-offs:
Google Maps JavaScript API: The most familiar mapping option. Strong place search, autocomplete, and geocoding. Per-API-call pricing that gets expensive at scale. Best for applications where users are already familiar with Google Maps and address search is a key feature.
Mapbox GL JS: Vector tile-based maps with smooth animations and full visual customization. Pricing based on map loads (first 50,000 loads/month free). React Mapbox GL or react-map-gl as the wrapper. Best for custom-branded maps and applications that need visual customization.
Leaflet.js / react-leaflet: Open source, tile-provider agnostic. Use OpenStreetMap tiles (free) or paid tile providers. Lower cost for high-volume applications. Less built-in functionality than Google or Mapbox; more custom code required.
The common requirements:
Marker clustering: When there are 10,000+ markers on the map, individual markers overlap. Clustering groups nearby markers at lower zoom levels and shows counts. Supercluster is the standard library.
Location storage: Geographic data stored as point type in Postgres with PostGIS extension, or as latitude/longitude float columns. PostGIS enables geographic queries (find all records within 5 miles of point).
Geocoding: Converting an address string to coordinates. Google Geocoding API or Mapbox Geocoding API. Cache results to avoid repeated API calls for the same address.
Mobile responsiveness: Map UIs need touch interactions (pinch-to-zoom, pan). Most mapping libraries support this; mobile testing is required.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Map UI scope is defined by the data displayed and the interactions required. Fixed-price from the feature list.

$7 per 1,000 map loads after the $200/month free credit (~28,000 loads). At high volume this gets expensive. Mapbox is more cost-effective for high-volume applications.
Yes — react-native-maps for React Native. Backed by Google Maps on Android, Apple Maps on iOS. Mapbox also has a React Native SDK.
