Fast PDF Generation API: A Native Puppeteer Alternative

Today, I am introducing Rynko. This is a new document generation platform built to help developers and AI agents design and generate PDF and Excel documents at scale without the traditional overhead. If you are building a SaaS, you eventually have to generate an invoice, a receipt, or a complex report. Developers usually waste days wrestling with CSS media queries or setting up resource-heavy HTML-to-PDF microservices using Puppeteer. Rynko provides the infrastructure to design, version, and generate documents deterministically. You can go from a blank canvas to a production-ready template in minutes and get back to building your core product. Architecture: Native Speed, No Bloat Rynko generates PDF and Excel documents from a single definition. This definition is a structured JSON component tree rather than HTML. We explicitly chose not to use HTML because headless browsers are heavy. A standard Chromium-based PDF generator can easily consume hundreds of megabytes of RAM per instance.
