Quaterio
Quaterio is a visual document editor that runs in the browser, like InDesign for the web. You design multi page documents with real pagination, headers, footers, page numbers and brand styling, then export them as pixel perfect, print ready PDFs. No desktop software and no designer required.
Start from templates with variable placeholders, so one layout can produce hundreds of personalized documents: invoices, reports, certificates, contracts and proposals. It handles QR codes, barcodes, PDF form fields and CMYK output with trim marks and bleed for professional print.
For teams that need automation, a REST API generates the same documents at scale from templates, HTML or Markdown, with batch generation and webhooks. Connectors pull live content from WordPress, Notion, Airtable, Shopify, HubSpot and more.
Free tier available, with paid tiers for API access, CMS integrations and white label output.
