Best Scrapers · Updated 2026-07-28
Open-source crawling and browser-automation frameworks compared on throughput, ergonomics and proxy support.
Frameworks are the right answer when you control the pipeline and want unit costs to fall as volume rises. The trade is that anti-bot handling becomes your problem.
We ran identical crawls on identical hardware and measured pages per minute, memory per worker and how cleanly each framework accepts rotating upstream proxies.
The mature asynchronous Python crawling framework — middlewares, pipelines, AutoThrottle and a proxy layer that scales to millions of pages.
Why it ranks here: Still the highest raw throughput per core for HTML-only crawls.
Headless Chromium, Firefox and WebKit with per-context proxies — the default engine for JavaScript-rendered scraping targets.
Why it ranks here: Best browser automation ergonomics with reliable cross-engine support.
Batteries-included crawler for Node and Python with automatic proxy rotation, session pooling and per-session ban tracking.
Why it ranks here: Best batteries-included crawler with built-in proxy rotation and session pools.
Chrome DevTools Protocol automation for Node, with the largest stealth-plugin ecosystem in scraping.
Why it ranks here: Leanest Chromium control when you only target Chrome.
The WebDriver standard — every language binding, every browser, and Grid for horizontal scale.
Why it ranks here: Widest browser and language coverage for legacy or QA-adjacent work.
Pass rate against Cloudflare, DataDome, PerimeterX and Akamai-protected pages.
Pages per minute at a fixed concurrency on identical hardware.
Docs quality, typed SDKs, retries, observability and local debugging.
How cleanly the tool accepts rotating residential or SOCKS5 upstreams.
Cost per 1,000 successful pages including retries and JS rendering.
Scores are recomputed whenever a vendor changes pricing, sourcing or infrastructure. This list was last verified on 2026-07-28. We earn commission from some links on this page; placement is decided from test data before any commercial terms are discussed.
Scrapy for volume on server-rendered HTML; Playwright when content only exists after JavaScript executes. Many teams run both and route per target.
Scrapy uses downloader middleware, Playwright and Puppeteer accept a proxy in the launch options, and Crawlee has a first-class ProxyConfiguration API.
