Want to see Generatr in action? We just published a full product demo on YouTube 🎥

Watch how templates, JSON, and the API come together to generate dynamic PDFs at scale — no HTML/CSS required.

Folders, multi-org, reusable partials.

Organise templates in a tree. Isolate clients in separate orgs with role-based access. Write your header once as a partial, reuse everywhere — one edit propagates instantly.

We built Generatr with one rule: everything you need to generate documents at scale, nothing superfluous.

Here's what that looks like 🧵

[Genetatr @generatrapp]

Native multi-language. One template, every market.

Translate your document into as many languages as you need. Pass ?lang=fr at API call time and you're done. One template. No drift. Always.

3. Instant live preview.

Paste your JSON test data → see the exact rendered document, paginated, in real time. No 'push to staging → generate → debug → repeat' cycle.

Hot take: template-as-code is a trap.

'Just write HTML/CSS templates' sounds fine until:

• Your legal team needs to tweak a clause
• Your ops team needs a new report format
• Every change requires a PR + deploy

We chose a visual editor for Generatr. Here's why 🧵

2. No rendering surprises.

HTML/CSS in Puppeteer is a minefield. Flexbox bugs. Font rendering differences. Page break orphans.

A structured JSON tree + dedicated layout engine = predictable output. Every single time.

[Genetatr @generatrapp]

Step 4 — Render & stream.

Resolved document → PDF rendered server-side → binary streamed back.

That's it. One POST. JSON in, PDF out.

No Puppeteer. No wkhtmltopdf. No 'it works on my machine.'

How does Generatr turn a visual template into a PDF in under 200ms?

No black magic. Just a clean pipeline. Let's break it down 🧵

[Genetatr @generatrapp]

Step 3 — Layout engine handles pagination.

This is the hard part. We calculate line heights, table row breaks, image dimensions — and split pages accordingly.

Headers, footers, page numbers — all positioned correctly. A4 or Letter. Every time.

Step 3 — Render & stream.

Resolved document → PDF rendered server-side → binary streamed back.

That's it. One POST. JSON in, PDF out.

No Puppeteer. No wkhtmltopdf. No "it works on my machine."

Step 2 — Templating engine resolves your data.

Variables, loops, conditionals — your template comes alive with real data.

We parse the JSON tree, inject your data, and produce a resolved document — all server-side, no browser needed.

[Genetatr @generatrapp]

Generatr: visual PDF template builder + dead-simple API.

• WYSIWYG editor — create templates in minutes
• Dynamic templating — loops, conditions, variables
• Live preview with real pagination
• Native multilingual + AI translations

Document generation at scale is still broken in 2026.

Most teams are stuck with:
• Hand-coded HTML/CSS templates nobody wants to maintain
• Page breaks that break the second data length changes
• Fragile Puppeteer/headless Chrome pipelines

There's a better way. 🧵

[Genetatr @generatrapp]

What if generating a PDF was just:

1. Design your template visually (no code)
2. POST your JSON to a single API endpoint
3. Get a production-ready PDF back

Page breaks, headers, footers, pagination — all handled.
One template, any language.

That's what we're building. ↓
