Component-first PDF generation

Turn your React components into a PDF API.

Push a component once. Generate invoices, reports, and contracts from any backend with a single HTTP call — no templating language, no proprietary editor, no copy of your logic to keep in sync.

bit-identical regeneration of any version

0 template copies to keep in sync

Real numbers, measured from production topology. We're pre-launch — no customer logos yet. '0 template copies' is a consequence of the architecture, not a benchmark.

The component is the template.

Most PDF APIs make you rebuild the document you already have in a templating language or a drag-and-drop editor — and keep that copy in sync by hand, forever. Renduo skips the second version entirely.

The usual way

Rebuild your invoice in Liquid, Jinja, or a proprietary drag-and-drop editor.
Every layout change happens twice — once in your app, once in the template.
The two copies drift. Someone finds out in production.

Renduo

Push the real React component your team already maintains.
No second language, no parallel editor format, nothing to keep in sync.
Versions are immutable — regenerate any document exactly as it was, byte-for-byte.

Three ways in, one API underneath.

However your team writes the first version, every generated document goes through the same POST /v1/generate (or the typed @renduo/sdk).

CLI

$ renduo push Invoice.tsx

Compile with esbuild on your machine and register a version from your own pipeline — scriptable, CI-friendly, git-tracked.

In-app editor

/dashboard/templates/invoice/edit

Write and preview a component directly in the dashboard. No local toolchain.

Playground

/dashboard/playground

Generate against a template your team already registered — test payloads fast.

Built like infrastructure, not a form builder.

Typed payloads & SDK

Your payload is the component's props — autocomplete and type errors in your IDE, not string-filled templates. The typed @renduo/sdk mirrors the OpenAPI contract: generate() and waitForGeneration() are compile-time checked.

Sync & async, on purpose

Sync is ephemeral by design — the PDF and the payload are never stored, only operation metadata. It's a compliance guarantee, not a gap. Async queues the job, stores the PDF for your plan's retention window, and notifies you by signed webhook.

Isolated Chrome sandbox

Your component never runs in Renduo's Node process — it renders in an isolated Chrome context with the network blocked. That's the standard HTML-to-PDF posture, applied to a full React component.

Immutable versions

Push the same slug again and you get a new version — the previous one keeps serving until you replace it. Regenerate any document exactly as it rendered, byte-for-byte.

Signed webhooks

HMAC-signed delivery with retries and exponential backoff, so you know a PDF finished without polling a status endpoint.

Custom fonts & assets

Bake your own fonts and images into the baked shell — the HTML container your component renders in — once. Every generation after that renders with your brand, not a fallback serif.

Role-scoped access

Admin, Developer, and Viewer — invite your team without sharing one API key between five people.
