By the Easy PDF Server Team
Every SaaS application that generates documents eventually faces the build-versus-buy decision. Should your team build an in-house HTML to PDF pipeline using open-source tools? Or should you pay for a dedicated PDF conversion API? The right answer depends on your scale, your team's time, and the importance of document generation to your core product.
Running your own HTML to PDF pipeline means managing headless Chromium instances (via Puppeteer, Playwright, or similar). Each instance consumes 200-500 MB of RAM. If you process 10 concurrent conversions, that is 2-5 GB of memory just for PDF generation — before your application code. You will need:
Building a reliable HTML to PDF service is not a one-day task. A production-ready implementation requires:
Assuming a developer cost of $75/hour, the initial build represents roughly $3,000-$6,000 in labor. Ongoing maintenance adds $500-$1,500/month depending on complexity and scale.
Open-source tools like wkhtmltopdf use outdated rendering engines that do not support modern CSS. If your templates use flexbox, CSS Grid, custom fonts, or CSS variables, you need a Chromium-based solution. Puppeteer gives you this but at the cost of managing the infrastructure described above.
Easy PDF Server charges a flat $20/month for unlimited API usage. Compare this to the infrastructure cost of running even a modest Chromium pool (a t3.medium EC2 instance costs roughly $30/month, and one instance may only handle a handful of concurrent conversions). The API pricing is simpler and often cheaper than what you would spend on cloud infrastructure alone.
A hosted PDF API eliminates all infrastructure concerns. No Chromium processes to manage. No memory monitoring. No font installation. No rendering engine updates. Your team focuses on building features that differentiate your product.
Integrating a REST API takes minutes, not weeks. You POST your HTML to a single endpoint and receive a PDF in response. The integration is the same regardless of your backend language — Node.js, PHP, Python, Ruby, or anything that can make HTTP requests.

If you need data locality but still want a turnkey solution, Easy PDF Server is also available as a self-hosted AMI on AWS Marketplace. You run it on your own EC2 instance at $0.39/hour while keeping all data within your AWS account. This gives you the operational simplicity of a pre-built solution with the data control of an in-house deployment.
For most SaaS teams, buying a PDF API is the clear winner. The infrastructure cost alone of running Chromium in production often exceeds the subscription price of a dedicated service. Factor in developer time and ongoing maintenance, and the build approach rarely makes financial sense unless you are operating at massive scale.
