What is BeautifulSoup?
BeautifulSoup is a Python library that parses raw HTML into a navigable tree. You search it with CSS selectors or tag names to pull out specific elements: titles, prices, links, tables. It's an HTML parser, not a browser, so it only works on whatever HTML the server returns. If a site renders content with JavaScript, BeautifulSoup sees an empty shell.
| Factor | BeautifulSoup | LLM Extraction |
|---|---|---|
| JS-rendered content | ✗ Needs Selenium or Playwright | ✓ Handled natively |
| Schema flexibility | Fixed CSS selectors per site | Prompt-based, works across sites |
| Site changes | Selectors break on HTML updates | Adapts automatically |
| Speed | Very fast | Slightly slower (LLM inference) |
| Cost | Free | Token costs per page |
BeautifulSoup is still a reasonable choice for parsing known, static pages where the HTML structure never changes: quick scripts, one-off extractions, or feeds you control. For anything dynamic, multi-site, or long-lived, selector-based scraping breaks constantly as sites update their HTML. For a direct comparison with Scrapy, see BeautifulSoup vs Scrapy.
Firecrawl Agent handles autonomous web extraction without selectors. Describe what you want, and it navigates, extracts, and returns structured data across any site.
