Runs full headless Chromium with 100% support for modern CSS — Flexbox, Grid, CSS Variables — so your invoices and reports look exactly like your browser preview.

If it renders in Chrome, it renders in your PDF — no surprises, no fallbacks.

Agent-native

MCP server for AI agents

A native Model Context Protocol server exposes PDF generation as a tool your agent can call directly, so coding assistants and autonomous workflows produce documents without you writing integration code.

Let Claude or Cursor generate your PDFs — no SDK, no glue code.

Delivery

Direct cloud delivery

Uploads the finished PDF straight to S3, GCS, or Azure Blob and returns a signed URL — with no intermediate storage, so your documents never sit on third-party disks.

Skip the download dance — your PDF lands in your bucket, not our servers.

Layout

Dynamic headers & footers

Inject templated headers and footers with dynamic variables like page numbers, total pages, and dates, so multi-page reports look professionally bound.

Page numbers, dates, and logos on every page — without hacking your HTML.

Reliability

Smart JavaScript wait strategies

Executes page JavaScript and waits using configurable strategies — networkIdle, domContentLoaded, or a custom CSS selector — so charts, fonts, and async data are fully rendered before capture.

Stop capturing half-loaded charts and empty tables.
