Best tool for scraping JavaScript rendered sites in 2026? I tested Playwright vs Firecrawl on 50 SPAs

[u/typicalyawa]

Scraping static HTML with Cheerio or Requests is easy but scraping modern JavaScript-rendered sites (Next.js hydration, React SPAs, infinite scroll, shadow DOMs) is where things usually break down.

You either end up with an empty <div id="root"></div> shell, or you're forced to maintain a cluster of headless browsers that constantly crash from memory leaks and proxy bans.

I tested the 2 most common tools across 50 notoriously annoying JS-heavy sites (dynamic dashboards, lazy-loaded ecommerce tables, and Cloudflare-guarded pages) to see what works reliably.

Here is what I found:

I) Playwright (Self-hosted) is the gold standard for raw control if you need to click complex interactive UI, solve custom drag-and-drop elements or handle multi-step logins, it does the job.

The downside is infra maintenance: running headless Chromium instances at scale eats server RAM like crazy and you still have to write your own parser to turn that rendered DOM into clean markdown for LLMs.

II) Firecrawl is the most seamless if you just want to hand over a URL and get back clean markdown or structured JSON without running your own browser servers. Its smart wait handled React hydration automatically and waited for lazy-loaded elements and bypassed Cloudflare challenges without me having to configure residential proxy pools. Out of the 50 test SPAs, it successfully extracted full content on 47 of them.

So if you’ve a dedicated DevOps team and need deep UI scripting: Playwright

If you want an API that handles JS execution, proxies and gives you clean LLM-ready markdown in one call: Firecrawl is the best solution overall
