The Developer API Alternative to WebScraper.io

Production-grade reliability

AlterLab is a cloud API designed for production workloads. No browser extensions to maintain, no desktop app dependencies, no manual intervention.

Anti-bot bypass built in

AlterLab handles CAPTCHAs, bot detection, and IP blocking automatically. Browser extensions cannot bypass these protections at scale.

Scale without limits

AlterLab handles thousands of concurrent requests. No seat-based pricing or cloud slot limitations.

// WebScraper.io uses browser extension
// 1. Install Chrome extension
// 2. Create sitemap visually
// 3. Run scraper in browser or cloud
// Limited by browser execution context

import requests

# Define extraction in code — runs in cloud at scale
response = requests.post(
    "https://api.alterlab.io/v1/scrape",
    headers={"X-API-Key": "YOUR_KEY"},
    json={
        "url": "https://example.com/products",
        "extract": {
            "products": ".product-card",
            "name": ".product-title",
            "price": ".product-price"
        }
    }
