Price Monitoring with BrowseFleet

The Problem

E-commerce sites aggressively block price scrapers with CAPTCHAs, IP bans, and fingerprint detection. Prices change frequently, requiring continuous monitoring across hundreds or thousands of product pages. Local scraping setups cannot handle the volume, and getting blocked means missing critical price changes.

The Solution

BrowseFleet's stealth mode and proxy rotation let you monitor prices without getting blocked. Schedule scraping jobs that run across concurrent sessions, solve CAPTCHAs automatically, and rotate proxies per session. The quick-action scrape endpoint extracts clean data from product pages in a single call.

import { BrowseFleet } from 'browsefleet';

const bf = new BrowseFleet({ apiKey: 'bf_...' });

const products = [
  'https://store.example.com/product/abc',
  'https://store.example.com/product/def',
  // ... hundreds of URLs
];

// Monitor prices in parallel
const results = await Promise.all(
  products.map(async (url) => {
    const session = await bf.sessions.create({
      stealth: 'full',
      proxy: getNextProxy(),
    });

    const browser = await puppeteer.connect({
      browserWSEndpoint: session.websocketUrl,
    });

    const page = await browser.newPage();
    await page.goto(url);

    const price = await page.evaluate(() =>
      document.querySelector('.price')?.textContent
    );

    await session.close();
    return { url, price, timestamp: Date.now() };
  })
);

// Compare with previous prices
const changes = detectPriceChanges(results);
if (changes.length > 0) notify(changes);
