GoGoDuk vs Google Maps Geocoding API
If your traffic is focused on Vietnam, GoGoDuk gives you the geocoding, reverse geocoding, address search, POI, and admin-boundary endpoints you actually use, free, with a data pipeline tuned for Vietnamese addresses. Here's the honest comparison.
Quick take
Google Maps is the right call when you need global coverage, Street View, or Places Photos. However, if your traffic is 100% focused on Vietnam, GoGoDuk is a far more accurate, reliable, and cost-effective alternative. GoGoDuk deeply understands Vietnamese address grammar (complex nested alley numbers, local abbreviations, automatic diacritic folding), quickly ingests the latest administrative boundary updates (such as Thu Duc City, merged communes/communal-level changes) which Google Maps often misses or takes months to sync, and is free or up to 10x cheaper than Google Maps.
Migration is usually under an hour for a typical address-search app — see the 5-minute migration guide.
Feature comparison
| Feature | GoGoDuk | Google Maps Geocoding API |
|---|---|---|
| Pricing | Free forever. 100 requests/day per account; higher limits on email request, still free. | $5 per 1,000 geocoding requests after free $200/month credit. Pay-as-you-go. |
| Credit card required | Never | Required for any usage |
| Vietnam address coverage | Primary focus. Handles ngõ/hẻm, diacritic folding, recent ward renames. | Global model. Misses some VN edge cases (alley numbering, recent admin reorgs). |
| Vietnamese diacritics | ASCII fold at index + query time. "Ha Noi" and "Hà Nội" both match. | Diacritic-aware but tokenization isn't tuned for VN address grammar. |
| Admin boundary polygons (province/district) | GeoJSON or WKT, 34 provinces + 3,323 districts. Free. | Not exposed via the Geocoding API. Requires Google's separate Maps Boundaries product (private beta, enterprise-only). |
| Reverse geocode to ward/district | /v1/reverse-geocode runs PostGIS ST_Contains against our boundaries. | Returns address components but ward (xã/phường) coverage is uneven in VN. |
| Global coverage | Vietnam only. | Worldwide |
| Street View / Places Photos | ||
| Official TypeScript SDK | @gogoduk/sdk on npm | @googlemaps/google-maps-services-js |
| Self-host option | On request for enterprise | |
| SLA | Free tier has no SLA; email us for enterprise terms | 99.9% on paid tiers |
When to stay with Google
- You geocode addresses outside Vietnam.
- You need Street View imagery, Places Photos, or the Places Details panel UI.
- You require an enforceable SLA today, not after a conversation.
- Your team has already invested deeply in Google's Maps JavaScript API, Routes, and Distance Matrix in one stack.
When to switch to GoGoDuk
- Your users are in Vietnam and the geocoder keeps missing addresses they can type correctly.
- You're paying a four-figure monthly Maps bill mostly for VN traffic.
- You need admin-boundary polygons for service-area math and don't want to license a separate dataset.
- You're building a prototype and the Google bill ramps faster than your usage warrants.
