Formfeed
PDFs, images, ZUGFeRD e-invoices and PDF/UA-1 files from templates, checked on every render.
You write a template (HTML/CSS with Jinja2, Liquid or Handlebars, a canvas design, or a Word file with tags), send JSON data, and one call returns the document or a link. E-invoices and PDF/UA-1 files are checked (Mustang, veraPDF) before delivery, and failures name the rule and field. Usable from SDKs, REST, CLI, an MCP server for AI agents, or Zapier/Make/n8n/Power Automate. Automated documents leave systems unchecked; Formfeed builds validation of e-invoices and accessible PDFs into the render, keeps data in the EU, and replaces DIY PDF rendering. Built for: Developers, AI agent builders and no-code teams generating invoices, certificates, reports and images, especially EU/German/French businesses needing e-invoices and GDPR-compliant hosting. Main features: ZUGFeRD 2.5 / Factur-X 1.09 e-invoices (EN 16931, Basic) as PDF/A-3b; PDF/UA-1 tagging checked by veraPDF, strict mode; MCP server with 10 tools, hosted or local; CLI with templates in Git, snapshot tests, GitHub Action; Browser editor on VS Code engine with page-accurate preview; Visual canvas editor for images (beta).
