Scrape Google Maps for business leads

Choose what to look for and where, and this runs the search against Google Maps, crawls each business’s own website for an email address, and adds the result to a database everybody shares. There is no signup, no API key and nothing to install. If somebody has already scraped what you are asking for, you get it back immediately and nothing is scraped at all.

The shared cache is the point. Every query anyone runs is recorded by term and area, and a query scraped in the last thirty days is answered from storage rather than repeated. So the second person to ask for “cabinet maker in Nashville TN” waits no time at all, and Google is asked once instead of once per curious visitor. You can see what has already been collected before spending a job on it.

Scraping itself is rate limited, and the limit is honest about why. A real browser has to walk the results and then visit each company’s website, which takes minutes per query and comes from one machine’s IP address. Google throttles that aggressively: measured on identical query sets, four concurrent workers produced seven HTTP 429 responses and 47 failed jobs across ten queries, while two were absorbed by retry logic. So jobs run two-at-a-time internally, queue rather than run in parallel, and each visitor gets a few per day. Searching the existing database is unlimited, because reading costs nobody anything.

A job can be paused and resumed between queries, and cancelled outright. Pausing stops the next query from starting rather than killing one mid-traversal, because a query that is nine tenths finished represents minutes of real work and throwing it away to honour a click a second earlier would waste exactly what this tool exists to conserve.

What comes back is the Google Maps record — name, category, address, phone, rating, review count, website — plus any email address found by crawling that website. The email is the part no official API can give you: Google’s Places API returns a phone number and a URL and stops there. Every result carries one-click WhatsApp, call and email buttons, one conversation at a time from your own account.

The built-in term lists cover industry broadly, on both sides of the transaction: electronics assembly and wood, sign and plastics shops, and also the bearing, pneumatics, hydraulics, PLC, VFD, motor, drive, automation and material-handling suppliers that sell into them. Anything not on the lists can be typed in — they are a shortcut past retyping “electronics manufacturing services in Minneapolis MN” correctly, not a boundary.
