Client Koi is an open-source Google Maps scraper Chrome extension. It automates local lead generation by deep-crawling B2B business websites to find verified emails and social media profiles, complete with an automated 2Captcha bypass.
Hey Product Hunt! 👋 I'm Shihab, the maker of Client Koi.
If you run an agency or do any B2B cold outreach, you know that Google Maps is the ultimate directory for local businesses. The problem? Google Maps doesn't list email addresses, and commercial scraping tools are incredibly expensive.
I built Client Koi as an open-source Chrome extension to solve this. Because it runs locally in your browser, it doesn't get instantly blocked like cloud scrapers.
What it does:
🕵️♂️ Deep Crawling: It visits the linked websites in the background to scrape hidden emails and social profiles (LinkedIn, FB, IG).
🤖 Anti-Bot Evasion: Integrated with 2Captcha to solve Google's rate limits while you sleep.
📊 Clean Exports: 1-click export to CSV/XLSX for your CRM.
It is 100% free and open-source. I'd love to hear your feedback, feature requests, or answer any questions you have about local scraping!
Been waiting for something this straightforward for local lead gen. The 2Captcha bypass alone saves me an hour per batch, and pulling socials from the deep crawl is a nice touch.
Scraped a local bakery cluster in under two minutes and the email hits actually matched the websites, which I did not expect. The captcha bypass is a nice touch for something free.
Skimmed a couple of B2B sites and the email harvesting actually pulled contact details I usually have to hunt for manually, that part is genuinely useful. The 2Captcha bypass handled the tricky ones without me babysitting it.
solid little extension, the captcha bypass actually works without fuss which surprised me. the deep crawl picked up some emails i couldn't find manually on a few local business sites.
A 2Captcha bypass is great but the crawling can get heavy on bigger sites, so adding a configurable crawl-depth limit and per-domain request throttling would help avoid getting blocked mid-session. That way users can dial it down for stubborn sites or speed it up for simple ones.
The 2Captcha bypass baked right into the workflow is genuinely sharp, it skips a step that breaks most scrapers. Love seeing an open source Chrome extension that takes the unsexy plumbing this seriously.
