I needed a way to extract hundreds of leads in seconds.</p> <h2> What I Built </h2> <p>I built <a href="https://gmapsscraper.io" rel="noopener noreferrer">GMapsScraper AI</a> — a tool thatuses AI to extract business data from Google Maps at scale.</p> <p><strong>Tech stack:</strong></p> <ul> <li>Next.js 14 (frontend)</li> <li>Cloudflare Workers (deployment)</li> <li>Supabase (auth + database)</li> <li>Go-based scraper (backend on Google Cloud Run)</li> </ul> <h2> How It Works </h2> <ol> <li>User enters a keyword + location (e.g. "dentist, New York")</li> <li>Backend spins up a headless browser to crawl Google Maps</li> <li>AI processes and structures the raw data</li> <li>Returns clean results: name, phone, email, website, rating, reviews</li> <li>One-click CSV export for CRM import</li> </ol> <h2> Key Technical Challenges </h2> <p><strong>Rate limiting</strong> — Google Maps aggressively blocks automated requests. Solution: rotating proxies + randomized delays + browser fingerprint rotation.</p> <p><strong>Data accuracy</strong> — Raw scraped data is messy. Used AI to normalize phone formats, validate addresses, and deduplicate results.</p> <p><strong>Speed</strong> — Users expect results in seconds. Implemented parallel scraping with a job queue system to handle concurrent requests.</p> <h2> Results </h2> <ul> <li>200+ leads extracted per search</li> <li>Average response time under 30 seconds</li> <li>Supporting 18 languages and global locations</li> </ul> <h2> Try It </h2> <p>If you're building outreach tools or need local business data, check it out: <a href="https://gmapsscraper.io" rel="noopener noreferrer">gmapsscraper.io</a></p> <p>Free trial available — no credit card required.</p> webdev ai saas javascript
