Every developer who needs to automate screenshots eventually asks: should I run Puppeteer/Playwright myself, or use a screenshot API? I've done this comparison across multiple projects. Here's the honest breakdown.

The DIY Headless Chrome Approach

Running your own Puppeteer instance looks simple:

const puppeteer = require ( ' puppeteer ' );

async function screenshot ( url ) { const browser = await puppeteer . launch (); const page = await browser . newPage (); await page . goto ( url , { waitUntil : ' networkidle2 ' }); const buffer = await page . screenshot ({ fullPage : true }); await browser . close (); return buffer ; }

Enter fullscreen mode

Exit fullscreen mode

Looks fine. Now wait for production to hit it.

Hidden Operational Costs

Memory : Each Chrome instance uses 200-400MB RAM. At 10 concurrent screenshots, that's 2-4GB just for Chrome. Kubernetes auto-scaling events, higher instance tier needed.

CPU : Chrome rendering is CPU-intensive.…
