Puppeteer

Open-source JavaScript library by Google for Chrome and Firefox automation and testing, with PDF generation as a secondary feature via page.pdf(). Also available as puppeteer-core without bundled browser. You host and manage the Chromium infrastructure. 94K GitHub stars, Apache 2.0 license.

Modern API

PDFBolt

PDF generation API that converts HTML, URLs, and reusable templates to PDF using the same Chromium engine as Puppeteer. Three endpoints (Direct, Sync, Async), webhooks, direct upload to your S3 bucket, and AI-powered template generation. Works with any programming language – no Node.js required.

Why Switch from Puppeteer to an API

Puppeteer is built for browser automation, not PDF generation.
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. Chrome doesn’t launch on Alpine without manual dependencies.

Memory leaks and zombie processes

Each Chromium instance uses 200-500 MB of RAM. A confirmed memory leak (GitHub #5893) 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. PuppeteerSharp (C#) is community-maintained with its own release cycle.

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.

Chromium updates you have to manage

Puppeteer releases roughly weekly, and many releases bundle a new Chromium version. Updates can change rendering behavior and break existing PDF output. You must test each update and redeploy. Pin a version and you miss security patches.

Cold starts and scaling complexity

Chromium cold starts add hundreds of milliseconds before rendering begins. Each PDF request spawns 4-6 Chromium processes (renderer, GPU, network, utility). Serverless deployments face additional challenges with package size limits and cold starts.

Puppeteer vs PDFBolt: A Closer Look

How the differences in infrastructure, developer experience, and PDF features affect real projects.

Infrastructure and Scaling

Puppeteer

Running Puppeteer in production means provisioning servers with enough RAM for Chromium, installing system dependencies (libnss3, libatk, dbus, font packages), and managing the Chrome process lifecycle. Deploying on AWS Lambda requires a special minimized package (@sparticuz/chromium) to fit within Lambda’s 250 MB size limit. At scale, you need browser pools, health checks, and auto‑restart on crashes.

PDFBolt

PDFBolt handles all infrastructure – Chromium instances, scaling, process management, and updates. The async endpoint processes documents in parallel and sends results via HMAC-SHA256 signed webhook, with direct upload to your S3-compatible bucket. No Docker, no Lambda packaging, no browser pools. Usage monitoring and request logs are available in the Dashboard.

Developer Experience

Puppeteer

A basic HTML to PDF script in Node.js with Puppeteer requires 15-20 lines of code: launch a browser, create a page, set content, configure PDF options, generate, close the page, close the browser, and handle errors at each step. You need to manage the browser lifecycle carefully – unclosed browsers leak memory, and unhandled crashes leave zombie processes. The API is JavaScript-only, so Python, PHP, Java, Go, and Ruby teams must build HTTP wrappers or use unofficial ports.

PDFBolt

PDFBolt converts HTML to PDF with a single HTTP POST request from any language. Send Base64‑encoded HTML or a URL to the /v1/direct endpoint and receive a PDF back. Most Puppeteer page.pdf() options map directly to PDFBolt parameters – format, margins, headers, footers, printBackground, pageRanges, and scale. The playground lets you test before writing code.

PDF-Specific Features

Puppeteer

Puppeteer’s page.pdf() covers basic PDF generation – page size, margins, headers/footers, and page ranges. But it has no built-in PDF compression (you need Ghostscript or qpdf), no print production output (PDF/X-4, CMYK, ICC profiles), no template system, and no way to manage or reuse designs. Tagged/accessible PDFs are experimental and not production-ready. For anything beyond basic HTML to PDF, you need additional libraries.

PDFBolt

PDFBolt adds features that Puppeteer does not have natively: PDF/X-4 and PDF/X-1a print production with CMYK conversion and ICC profiles (Fogra39, Fogra51, SWOP, GRACoL), built-in PDF compression at four levels, tagged/accessible PDFs, and a Handlebars-based template system with a visual designer and AI template generation.

"Amazingly, the owner personally helped solve the issues I was having creating an exported lesson plan with hyperlinks and complex styling. This is a great piece of software. But more importantly, it’s the people behind a product that truly make a company great. His willingness to support my project without payment is truly unique – a rare product and a rare individual. This product just works. Thank you, PDFBolt!"

"There's a lot of products that convert to PDF out there, but this one stood out to me, because the output quality is good, it's very easy to use, and pay per use. I also love the interactive API documentation, my request just worked out of the box in my app. And of course the focus on privacy, which is important when working with GDPR data. (...) PDFBolt just works, so I can focus on the business logic."

Frequently Asked Questions

Common questions about using Puppeteer for PDF generation and switching to PDFBolt.

Yes, Puppeteer is free and open-source (Apache 2.0 license, maintained by Google). However, running Puppeteer in production requires server infrastructure – compute instances with enough RAM for Chromium (200–500 MB per instance), container orchestration for scaling, and engineering time to build job queues, error recovery, and monitoring. PDFBolt offers a free tier with 100 documents per month, with paid plans starting at $19/month – all infrastructure included.
Yes, but it requires significant infrastructure work. You need to manage Chrome process lifecycle (launch, reuse, close), handle memory leaks and zombie processes, implement queuing for concurrent requests, set up container orchestration for scaling, and handle Chrome crashes gracefully. Puppeteer was designed primarily for browser automation and testing, not as a dedicated PDF generator. For teams looking for a Puppeteer alternative for PDF, PDFBolt is a purpose-built replacement with all infrastructure concerns handled.
Yes. PDFBolt uses a real Chromium browser for rendering, ensuring the same high-quality output you get from Puppeteer. Your existing HTML, CSS, and JavaScript will render identically – you can convert HTML to PDF without Puppeteer while keeping the same result. Unlike some Puppeteer alternatives that use different engines, PDFBolt handles all the Chromium infrastructure so you just make an API call.
Pyppeteer was an unofficial Python port of Puppeteer. It has been largely unmaintained since February 2024 and is stuck on an older Chromium version. For Python PDF generation, PDFBolt’s REST API works with the standard requests library – no special dependencies, no async/await complexity. See the Python quick start guide for a working example.
No. Both Puppeteer and PDFBolt use Chromium for rendering, so your HTML, CSS, and JavaScript will render identically. Most page.pdf() options map directly to PDFBolt parameters – format, margins, headers, footers, printBackground, pageRanges, and scale. The only change is replacing Puppeteer’s browser management code with an HTTP POST request.
Puppeteer (Google) and Playwright (Microsoft) offer similar PDF generation APIs using the Chrome DevTools Protocol. Benchmarks suggest Playwright is faster on warm renders and can produce smaller output files. However, both require self-hosted Chromium infrastructure with the same operational challenges – memory management, scaling, and Docker deployment. PDFBolt eliminates these concerns for both Puppeteer and Playwright users.
