The best alternative to Puppeteer for PDF generation

Same Chromium-based PDF quality without managing Chrome, Docker, or memory leaks. DocuQueue is a managed HTML to PDF API — works with any language, no Node.js required.

# Puppeteer: Launch browser, create page, render, close
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setContent(html);
await page.pdf({path: 'output.pdf'});
await browser.close();

# DocuQueue: One API call
curl -X POST https://docuqueue.com/api/v1/convert-html \
  -H "api-key: wp2_your_key" \
  -H "Content-Type: application/json" \
  -d '{"html": "<h1>Hello</h1>"}' -o output.pdf

Why switch

Puppeteer wasn't built for PDF generation

Puppeteer is a browser automation tool. Using it for PDF means managing infrastructure that has nothing to do with your product.

Infrastructure you have to manage

Puppeteer auto-downloads Chromium, but you still need a server with enough RAM, system libraries (libnss3, libatk, dbus), and font packages. Production deployments typically run Puppeteer in Docker, adding container management to the stack.

Memory leaks and zombie processes

Each Chromium instance uses 200-500 MB of RAM. A confirmed memory leak causes gradual accumulation. If your Node process crashes mid-render, orphaned Chrome processes remain. On a 2 GB VPS, 10-20 concurrent renders is the ceiling before OOM kills start.

Node.js lock-in

Puppeteer is a JavaScript library — there is no official SDK for Python, PHP, Java, Go, or Ruby. Pyppeteer (Python port) has been largely unmaintained since February 2024. Teams using other languages must build HTTP wrappers or use unofficial ports.

No built-in queue or webhooks

Puppeteer has no async processing, no webhook callbacks, and no retry logic. For production use you need to build your own job queue (Redis, Bull, RabbitMQ), implement error recovery, and write S3 upload code.

Why DocuQueue

Looking for an alternative to Puppeteer?

Puppeteer is a browser automation tool. Using it for PDF means managing infrastructure that has nothing to do with your product. DocuQueue does the same thing, except we handle all of that.

No Docker required

Scales to 10K+ PDFs

No capacity planning. Auto-scales behind the scenes.

Real support

Not a GitHub issue that goes unanswered for months.

URL-to-PDF built in

Convert live URLs to PDF with one parameter.

Async processing

Built-in job queue. No Redis or Bull setup needed.

Batch processing

Generate hundreds of PDFs from a single CSV upload.

Custom DOCX templates

Upload your own Word documents as templates. Fill them with data via the API. No HTML or CSS required.

Migration

Replace Puppeteer with one API call

Puppeteer (Node.js)

const puppeteer = require('puppeteer');

async function generatePdf() {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  
  await page.setContent(html, {
    waitUntil: 'load'
  });
  
  await page.pdf({
    path: 'invoice.pdf',
    format: 'A4',
    margin: {
      top: '20mm',
      bottom: '20mm'
    },
    printBackground: true
  });
  
  await browser.close();
}

DocuQueue (Any Language)

import requests

html_content = "<h1>Invoice #1042</h1>"

response = requests.post(
    "https://docuqueue.com/api/v1/convert-html",
    headers={"api-key": "YOUR_KEY"},
    json={
        "html": html_content,
        "format": "A4",
        "margin": {
            "top": "20mm",
            "bottom": "20mm"
        }
    }
)

# Save PDF
open("invoice.pdf", "wb").write(response.content)

Decision Guide

When to choose which

Choose Puppeteer if...

Need full browser automation beyond PDF — testing, scraping, screenshots
Already have Puppeteer infrastructure and PDF is a side feature
Need pixel-perfect Chrome control — custom flags, extensions
Need offline or air-gapped PDF generation
Very low volume and already have Node.js installed

Choose DocuQueue if...

PDF generation is a core feature — invoices, reports, contracts
Want to avoid managing Chromium infrastructure
Need PDFs from Python, PHP, Java, Go, Ruby, or C#
Need async processing at scale with webhooks
Want a fully managed service with 99.9% uptime
