PDF API Cost Calculator — Serverless HTML-to-PDF Rendering API vs Self-Hosted Headless Chromium TCO
A command-line tool and benchmarking framework to calculate the Total Cost of Ownership (TCO) of document generation architectures. Compares self-hosted Headless Chromium / Puppeteer clusters against managed document generation APIs including CraftMyPDF, APITemplate.io, DocRaptor, and Adobe PDF Services.
⚡ Installation & Usage
# Install via pip
pip install pdf-api-cost-calculator
# Calculate TCO for 15,000 monthly invoices
pdf-api-cost-calculator --docs 15000
# View command line options
pdf-api-cost-calculator --help
💸 Why Self-Hosting Puppeteer / Chromium Is an Anti-Pattern
- Chromium Memory Leaks: Renders leak 80–250 MB per job. Node.js worker pools crash under high-concurrency billing cycles.
- Cold Starts in Lambda: AWS Lambda 1024MB–2048MB runtimes require 3–8s cold starts; missing OS fonts cause tofu boxes.
- DevOps Overhead: 12+ hours/month spent maintaining font packages, Chromium dependencies, and headless sandbox CVEs ($1,200/mo eng drag).
