Geolocation-based services in Bubble use the geographic address field type, Google Maps integration, and distance-based search constraints to find nearby users or businesses. This tutorial covers detecting the user's location, storing locations in the database, building proximity search with radius filtering, and implementing geofencing triggers.
Overview: Building Geolocation-Based Services in Bubble
This tutorial shows how to build location-aware features in your Bubble app including nearby search, map displays, and geofencing. These features are essential for delivery apps, local marketplaces, and any service that connects users based on proximity.
Prerequisites
- A Bubble app with a Google Maps API key configured
- Geographic address fields on relevant Data Types
- Basic understanding of Repeating Groups and Workflows
- Familiarity with the Google Maps element in Bubble
Step-by-step guide
Configure Google Maps and geographic address fields
Configure Google Maps and geographic address fields
Go to Settings → General tab and enter your Google Maps API key (get one from console.cloud.google.com). Enable the Maps JavaScript API, Geocoding API, and Places API. In the Data tab, add a geographic_address field (type: geographic address) to any Data Type that needs location — User, Business, Listing, etc. The geographic address type automatically stores latitude, longitude, and formatted address.
Expected result: Google Maps is configured and location fields are ready on your Data Types.
Detect and store the user's current location
Detect and store the user's current location
On your page, use the Current geographic position data source to detect the user's location (requires browser permission). Create a workflow on page load or a Locate Me button: Make changes to Current User → set location = Current geographic position. For manual address entry, use a SearchBox element set to Geographic places — this provides Google Places autocomplete. When the user selects an address, store it in the database.
Pro tip: Always ask for location permission with context — explain WHY you need their location before the browser prompt appears.
Expected result: User locations are stored in the database either via automatic detection or manual address entry.
Build proximity search with distance radius
Build proximity search with distance radius
On your search page, add a SearchBox for the center location and a SliderInput for the search radius (e.g., 1-50 miles). Add a Repeating Group with a search constraint: location is within [radius] miles of [center address]. This uses Bubble's built-in geographic constraint. Sort results by distance. Display the distance from center for each result using the :distance from operator on the geographic address field.
Expected result: Users can search for nearby items within a specified radius and see distance from their location.
Display results on an interactive Google Map
Display results on an interactive Google Map
Add a Map element to your page. Set its Data source to the same search used in the Repeating Group. Add a marker for each result showing the item's location. Customize marker icons based on category or type. When a user clicks a marker, display a popup with the item's details. Link the map and Repeating Group so clicking a list item centers the map on that location, and clicking a marker highlights the corresponding list item.
Expected result: Search results appear both in a list and as markers on an interactive map.
Implement geofencing and location-based triggers
Implement geofencing and location-based triggers
Create a backend workflow called check-geofence that runs when a user's location updates. Define geofence areas as geographic address + radius pairs stored in a GeoFence Data Type. Check if the user's current location is within any geofence using the geographic distance constraint. If they enter a geofence, trigger an action (send notification, unlock content, log visit). For complex location-based applications with real-time tracking, RapidDev can help build optimized geolocation systems.
Expected result: Actions trigger automatically when users enter or exit defined geographic areas.

Why it's a problem: Not enabling the required Google Maps APIs
How to avoid: Enable all three APIs in Google Cloud Console: Maps JavaScript API, Geocoding API, and Places API.
Why it's a problem: Using text fields instead of geographic address fields
How to avoid: Always use the geographic address field type for locations. It stores latitude, longitude, and formatted address.
Why it's a problem: Not requesting location permission with context
How to avoid: Show a message explaining why location is needed before triggering the browser permission request.
Best practices
- Use geographic address field type for all location data
- Enable Maps JavaScript, Geocoding, and Places APIs in Google Cloud
- Provide a manual address entry option as fallback for denied permissions
- Show distance from the user's location in search results
- Use map markers with category-based icons for visual clarity
- Cache the user's location to avoid repeated permission requests
- Set Google Maps API key restrictions to prevent unauthorized usage

I want to build location-based features in my Bubble.io app: nearby search within a radius, Google Maps display with markers, and geofencing triggers. Can you outline the setup, data model, and search configuration?
Add geolocation features to my app. I need user location detection, proximity search within a radius, results displayed on a Google Map with markers, and geofencing that triggers notifications when users enter defined areas.
Frequently asked questions
Does Google Maps API cost money?
Google provides $200 free credit per month for Maps API usage. For most apps, this covers thousands of map loads and geocoding requests. Monitor usage in Google Cloud Console.
Can I use a different map provider?
Bubble's built-in Map element uses Google Maps. For alternatives like Mapbox, use a plugin or HTML element with the provider's JavaScript library.
How accurate is browser geolocation?
GPS on mobile is accurate to 5-10 meters. Desktop browser location (based on IP and WiFi) is accurate to 50-500 meters depending on the environment.
Can I calculate driving distance instead of straight-line distance?
Bubble's built-in distance calculation is straight-line (as the crow flies). For driving distance, call the Google Directions API via the API Connector.
How do I handle users who deny location permission?
Show a manual address entry SearchBox as fallback. Store their entered address and use it for proximity features instead of auto-detection.
Can RapidDev help with complex location features?
Yes. RapidDev can build advanced geolocation features including real-time tracking, route optimization, delivery zones, and integration with mapping services.
