Cheerio
Open source scraping frameworks give engineering teams full control over their web data pipeline. You choose where to deploy, how to scale, and what data to collect – with no vendor lock-in or per-request pricing. The trade-off is infrastructure maintenance and anti-bot engineering, which commercial APIs handle for you.
How Cheerio compares
Frequently asked questions
Is Cheerio free?
Yes. Cheerio is free and released under the MIT license. You install it from npm, with no paid tiers, license keys, or usage fees. It is a library you add to a Node.js project rather than a hosted service, so there is no account or billing. Your only cost is the compute you run it on. The maintainers fund development through sponsors, but the package stays free to use commercially.
Is Cheerio open source?
Yes. Cheerio is open source under the permissive MIT license, with development on GitHub at cheeriojs/cheerio. You can read, fork, and modify the code, and the MIT terms allow commercial use without royalties. Because it is a plain npm package with no server component, you run it entirely on your own infrastructure. That makes it straightforward to vendor, audit, or pin to a specific version inside your build.
Does Cheerio render JavaScript?
No. Cheerio parses static HTML and XML using jQuery-like selectors, but it does not execute JavaScript or run a browser engine. Content injected client-side by a single-page app will be absent from what Cheerio sees. For JavaScript-heavy pages you render the DOM first with a headless browser such as Puppeteer or Playwright, then hand the resulting HTML to Cheerio for extraction.
What is Cheerio best used for?
Cheerio fits server-side extraction from static HTML in Node.js. Common jobs include parsing fetched pages, scraping markup that arrives fully rendered, reading RSS or XML, and transforming documents. It has no HTTP client, no crawler, and no JavaScript engine, so it expects you to supply the HTML. Teams reach for it when they already know jQuery selectors and want a fast, lightweight parser rather than a full scraping platform.
What is the best alternative to Cheerio?
It depends on what is missing. For JavaScript-rendered pages, pair it with or replace it by Puppeteer, which drives a headless browser. For a full crawling framework with queues, retries, and proxy handling, Crawlee wraps Cheerio and browser engines together. If your stack is Python rather than Node.js, Beautiful Soup is the direct equivalent. Cheerio stays the simplest choice when you only need to parse static HTML you already have.
How does Cheerio compare to Beautiful Soup?
They solve the same problem in different languages. Both are parsing libraries with no HTTP client, no JavaScript rendering, and no crawler, so both expect you to fetch HTML separately. Cheerio runs in Node.js with a jQuery-style selector API, while Beautiful Soup runs in Python with its own navigation methods. Choose Cheerio if your scraper is JavaScript or TypeScript, and Beautiful Soup if the surrounding code is Python.
