DocPuffin is a cloud-based service that lets you automatically generate PDFs from reusable templates using JSON data and an API.

Why build another PDF API?

• PDF Generation API: Create business documents like invoices, reports, and contracts

• Automation Integrations: Connect directly with tools like Zapier, Make.com, and n8n via REST API or native workflow connectors.

• No subscriptions: Credit packs instead of a subscription-based usage meter.

The stack: pdf-lib for PDF generation, it’s still pre-launch. The render engine is already working, and that’s what you’re using in the demo. API keys, documentation and the template editor will be coming over the next few weeks.

I’m preselling founding credit packs for $39, which includes 5,000 renders.
