Generate PDFs from JSON: A Lightweight Alternative to Headless Browsers

Traditional PDF generation tools like Puppeteer introduce significant operational overhead—bulky Chromium binaries, memory leaks, and performance bottlenecks under load. By shifting to a JSON-API pattern, developers can generate PDFs more reliably without browser dependencies, making it ideal for production environments handling invoices, reports, and certificates. This approach also enables features like editable PDFs that headless browsers cannot provide.
