Price Monitoring
Track Competitor Prices via API
Monitor competitor prices across any e-commerce site. SnapRender handles JavaScript rendering, Cloudflare bypass, and anti-bot detection — you get clean, structured price data from product pages. Build automated price tracking with scheduled scrapes and custom alerts.
Manual price tracking doesn't scale
Checking competitor prices manually — or relying on browser extensions — breaks down quickly. Modern e-commerce sites use JavaScript rendering, dynamic pricing, A/B testing, and aggressive anti-bot protection that block simple scrapers.
SnapRender renders each product page in a real headless browser, extracts the price data using CSS selectors, and returns structured JSON. Schedule these calls with cron jobs and you have a fully automated price monitoring system — without managing browsers, proxies, or CAPTCHA solvers.

Scrape on a schedule
Use cron jobs, serverless functions, or workflow tools to call SnapRender's scraping API at your desired frequency. Extract price, availability, and seller data with CSS selectors.
