The Best 15 Google Maps Scrapers of 2025

by
Google Maps Scrapers

Learn about the top Google Maps scrapers available, their unique features, and how they can enhance your data collection efforts. In this guide, you’ll learn: What a Google Maps scraper is Why it outperforms the Google Places API Essential factors to consider when choosing a Google Maps scraping service The best Google Maps scrapers on the market Let’s dive in! What Is a Google Maps Scrapers? A Google Maps scraper is a specialized tool, service, or solution designed to retrieve information from Google Maps pages. It extracts specific geolocated data based on user-defined queries, enabling highly targeted data collection. To work effectively, a Google Maps scraping service must handle complex tasks such as bypassing anti-scraping measures, managing proxies, and implementing geo-targeting. Once the data is extracted, the scraper automatically parses it into user-friendly formats such as JSON or CSV. For more details, follow our tutorial on how to scrape Google Maps with Python. Why Do You Need It Instead of the Places API? Google features an official Places API to programmatically retrieve Maps data. While this API is widely used, it comes with limitations that make scraping a more appealing option. Here’s why choosing a Google Maps scraper over the Places API is beneficial: Cost Efficiency: The Places API follows a strict pay-as-you-go pricing model, whereas scraping providers generally offer more cost-effective plans. Freedom from API Rate Limits: The Places API imposes rate limits, restricting how much data you can fetch within a given timeframe. Scraping helps bypass these constraints. Access to All Data Points: The data returned by the Places API is limited and may change over time. Scrapers, however, can capture all available information on Google Maps pages with no restrictions. For further insights, read our guide on web scraping vs API. Aspects to Consider When Evaluating Google Maps Scrapers Below are essential factors to consider when choosing the best Google Maps scrapers: Features: Capabilities and functionalities offered by the scraping service.
