The Challenge

Why price tracking is hard

Without Spider

  • E-commerce sites use heavy JavaScript rendering
  • Anti-bot protection blocks traditional scrapers
  • Prices change frequently and manual tracking does not scale
  • Regional pricing requires global proxy access

With Spider

  • Full JavaScript rendering with headless browsers
  • 99.9% success rate with built-in anti-bot bypass
  • Webhook alerts for price changes and stock updates
  • 199+ countries for region-specific pricing data

Capabilities

Everything you need for price intelligence

Batch Crawling

Track prices across thousands of product URLs in a single request. Spider processes them in parallel so you get results in seconds, not hours.

Structured JSON

Extract product names, prices, SKUs, and availability as clean JSON. Use CSS selectors or AI extraction to target exactly the data you need.

Webhook Alerts

Get notified the moment a price changes or a product goes out of stock. Spider sends real-time webhook events so your team can act fast.

Global Proxies

Access region-specific pricing from 199+ countries. See the exact price your customers see, wherever they are in the world.

Anti-Bot Bypass

E-commerce sites run aggressive bot detection. Spider rotates fingerprints, solves challenges, and renders JavaScript with a 99.9% success rate.

Historical Tracking

Store every crawl result to build price trend data over time. Spot patterns, predict drops, and time your pricing strategy around competitor moves.

Quick Start

Extract prices in five lines

Use CSS selectors to pull exactly the product data you care about. Spider handles rendering, proxies, and anti-bot challenges behind the scenes.
