Why Agencies Choose Client Koi
Three reasons why Client Koi is the top choice for B2B lead generation from Google Maps.
100% Free, Forever
While competitors charge $29-$199 per month for similar features, Client Koi is completely free. No hidden costs, no usage limits, no credit card required. Download from GitHub and start scraping immediately.
Open Source & Transparent
Client Koi is the only major Google Maps scraper that is fully open source. You can inspect the code, verify there's no data collection, and contribute improvements. Your data never leaves your browser.
Deepest Email Extraction
Most scrapers only capture what Google Maps shows directly. Client Koi goes further — it visits each business's website to find hidden emails, social media links, and contact forms that surface-level tools completely miss.
Detailed Alternative Breakdowns
A closer look at how each tool compares for different use cases.
Client Koi vs. Instant Data Scraper
Instant Data Scraper is a popular free Chrome extension, but it's a general-purpose web scraper — not purpose-built for Google Maps. It can extract visible table data from any website, but it cannot visit linked business websites to find hidden email addresses. It also lacks CAPTCHA bypass, anti-ban mechanics, and social media extraction. If you only need basic name/address/phone data, Instant Data Scraper works. If you need emails, social links, and overnight capability, Client Koi is the clear winner.
Client Koi vs. Outscraper
Outscraper is a powerful cloud-based scraping service with excellent data quality. However, it starts at $29/month and charges per record for large volumes. For agencies scraping thousands of leads monthly, costs can quickly reach $100-$200. Client Koi provides comparable email extraction and social media scraping completely free. The trade-off: Outscraper runs in the cloud (no Chrome needed), while Client Koi runs locally in your browser.
Client Koi vs. Maps Scraper
Maps Scraper (also known as Google Maps Data Extractor) offers a free tier with limited exports and a paid tier for full access. It extracts basic business information but does not perform deep website scraping for hidden emails or social media profiles. Client Koi's deep scraping engine visits each business's actual website, giving you significantly more contact data points per lead — at zero cost.
