Generate 1,000 Website Screenshots 10x Faster Than Puppeteer

Generate 1,000 Website Screenshots 10x Faster Than Puppeteer You need to screenshot 1,000 websites. Quality assurance team. Website monitoring. Visual regression testing. Design snapshots for a marketplace. So you write a Puppeteer script. Spin up a Node process. Iterate through your URL list. Capture. Save. Next URL. If you're doing this on one machine, 1,000 screenshots takes 20–30 minutes. You're limited by local Chromium resource contention. There's a faster way. And it doesn't require managing browser infrastructure. Why Puppeteer Gets Slow for Bulk Screenshots Puppeteer is designed for reliability and DOM manipulation, not bulk-parallel execution. When you're screenshotting 1,000 URLs: Chromium overhead : One browser instance processes URLs sequentially. Initialization is amortized, but each navigation has latency (DNS, TLS, page load, render). Single-machine bottleneck : You can spawn multiple processes, but you quickly hit CPU/memory limits.
