Screenshot API vs Puppeteer: When to Use Each

Capturing web screenshots at scale with Puppeteer means managing headless browsers, memory leaks, and timeouts. Here's when a Screenshot API makes more sense.

The Problem with Puppeteer at Scale

const puppeteer = require('puppeteer');
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
const screenshot = await page.screenshot({ fullPage: true });
await browser.close();

This works locally. In production, you deal with:

Memory leaks from zombie browser processes
Timeout handling for slow pages
Chrome binary management across environments
Scaling to hundreds of concurrent captures

The API Alternative

const res = await fetch('https://captureapi.dev/v1/screenshot?url=https://example.com&fullPage=true', {
  headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
});
const image = await res.blob();

One HTTP call. No browser management.

When to Use an API

Screenshots in production at scale
Multiple viewports/devices needed
PDF generation from URLs
OG image generation
Visual regression testing

When to Keep Puppeteer

Complex interactions before capture
Local development/testing only
Full browser automation (clicks, forms)

Try It
