pdfs.build is a PDF template engine and rendering API for developers and teams that generate documents from code. You define a template once with dynamic variables, then POST JSON data to the REST API and get a pixel-perfect PDF back in milliseconds.

There are three ways to build a template. You can describe the document in an AI chat editor and watch a live preview update as the agent writes the layout, the schema and the sample data. You can import an existing .docx file and keep working from there. Or you can let your own AI agent do the work over the hosted MCP server, so tools like Claude Code or Cursor can create, test and publish templates for you.

Rendering runs on the Typst typesetting engine, so tables, page breaks, headers and footers and long multi-page layouts behave the way print expects instead of the way a browser guesses.

For SaaS products, pdfs.build ships an embeddable template editor. Drop it into your own app and your customers can design their own invoices, reports, contracts and certificates without leaving your product. Webhooks tell your backend when a render finishes, a template gallery gives you ready-made starting points, and SDKs cover the common languages.

Typical uses include invoices, statements, reports, certificates, contracts and letters: any document you would otherwise assemble by hand or maintain as fragile HTML-to-PDF code.

Pricing is simple. The free plan includes 50 renders and 50 AI design credits every month. Paid plans start at $10 a month, and extra credits and renders you buy never expire.
