Both Zilvo and Outscraper can turn a business category and geography into structured Google Maps data.
The difference is not whether they can scrape Google Maps. It is how much product you want around the scrape.
Outscraper is a mature cloud data platform with advanced filters, enrichment, several export formats and API access. Its Google Maps product is pay-as-you-go and currently starts free for 500 places, then costs $3 per 1,000 through 100,000 places and $1 per 1,000 above that.
Zilvo is narrower. Enter the business category and geography. Zilvo breaks large markets into smaller searches where necessary, collects the businesses, removes duplicates and gives you a CSV.
500 free credits = up to 1,000 unique Google Maps businesses. No card required.
