Outscraper is providing fast and reliable data on Google Maps locations, in a simple and intuitive interface. The platform has advanced features, yet is user friendly enough. In the last 12 months, we used Outscraper to extract relevant public data regarding 120,000+ locations.

Outscraper is the best API service I’ve ever had to discover by pure luck (in an article from Medium.com) - was seeking something like this since 2019 and this platform is the only one actually working and doing the job.

What an awesome tool for getting marketing lead prospects. It's much faster than the estimates they give when doing a scrape. (It's always good to under-promise & over-deliver to your customers)...

This service has been extremely helpful for me. Apart from their super fast API for various services, their amazing support is something that would make you go back to them. Dana from Outscraper team had helped me tirelessly for 3 days when I got into an issue and the dev team even made a spot update in their SDK package to suit my requirements. Highly recommended!

I wish I had found it sooner. I've been manually collecting data from Google Maps for the past 15 months! The first search produced more usable data in 20 minutes than my 15 months did altogether.

Outscraper is the best scraper I've found. I cannot believe how well it works, how much data I get back, with no errors or headaches. I can make any directory site I want now
