Should I use Puppeteer for recurring crawl jobs?

Sometimes — but only if you really need a browser.

Use Puppeteer for recurring crawl jobs when:

• The site is heavily JavaScript-rendered
• Content only appears after user interactions like clicks, scrolling, or login
• You need to capture rendered DOM, screenshots, or PDFs
• Anti-bot measures require a real browser session

Avoid Puppeteer when:

• The data is available in HTML or API responses
• You can use a lighter tool like requests/axios + Cheerio/BeautifulSoup
• You care about speed, cost, and stability
• The crawl runs frequently and needs to scale

Why Puppeteer can be a poor default for recurring jobs

• Slower than direct HTTP scraping
• More resource-intensive: CPU, memory, and disk
• More likely to break due to:
  • browser updates
  • site changes
  • flaky timing / waits
• Harder to scale across many pages

Better pattern

For recurring crawls, prefer a layered approach:

1. Try HTTP requests first
2. Fall back to Puppeteer only for pages that require rendering
3. Cache results and reuse sessions where possible

Practical recommendation

• Yes, use Puppeteer if the target site truly needs browser automation.
• No, don’t use it as the default for all recurring crawl jobs.
