Real documents teams are generating today
Design a template once, then generate professional PDF and Excel documents from your data — no Puppeteer, no ExcelJS, no headless browsers.
Design a template
Build your document in the visual designer, or define it as JSON — 28 components, charts, barcodes, and form fields.
Send your data
POST a template ID and your JSON data to one endpoint — from any language, SDK, or no-code platform.
Get PDF or Excel
The native engine renders your document in under a second and returns a download URL. Same template, either format.
Where teams put Rynko to work
Not demos. Actual document workflows running in production today.
How Rynko does it
Design an invoice template once in the visual designer, then post your order data to a single API call. Rynko returns a pixel-perfect PDF in under a second — no headless browser, no HTML-to-PDF glue code.
What you get
How Rynko does it
Map your data to a report template with native charts and tables. Generate the same report as a PDF for distribution or an Excel workbook with live formulas — from one template.
What you get
How Rynko does it
Batch-generate hundreds of certificates from a single template and a list of recipients. Rich text, custom fonts, and precise positioning keep every certificate on-brand.
What you get
How Rynko does it
Generate Excel workbooks with real formulas, named ranges, and cell formatting, or the same statement as a PDF for sign-off. One template drives both formats.
What you get
How Rynko does it
Merge deal data into a contract template and render a print-ready PDF with fillable form fields and signature placeholders. No manual copy-paste, no formatting drift.
What you get
How Rynko does it
Render shipping labels and manifests with built-in barcode and QR support. Trigger generation straight from your warehouse or order system via API or webhook.
What you get
Design once. Generate PDF and Excel.
A native rendering engine — built on Yoga layout, not a headless browser — produces both PDF and Excel from the same template definition. Sub-second, deterministic, and precise.
Components
Text, headings, tables, images, columns, loops, and conditionals — plus rich text with TextRuns for fine-grained inline styling.
Charts & barcodes
Eight chart types and ten barcode formats render natively — no external services, no screenshotting a web page.
PDF form fields
Fillable text inputs, checkboxes, radios, dropdowns, dates, and signature placeholders for ready-to-sign documents.
Native engine renders most documents in under a second
JavaScript expressions and native Excel formulas both supported
Headless browsers to install, patch, or scale
Generate reports straight from your database, on a schedule.
Run an on-premise agent inside your network to produce scheduled, data-driven PDF and Excel reports — a modern replacement for legacy tools like Cognos. Your data never leaves your environment: the agent works zero-knowledge, so Rynko never sees your database.

Headless browsers are fragile
Puppeteer and wkhtmltopdf need constant patching, break on upgrades, and are painful to scale under load.
No Excel from the same source
HTML-to-PDF tools can't produce a real Excel workbook — you end up maintaining a second, separate pipeline.
One native engine
Rynko renders PDF and Excel from the same template with a native engine — sub-second, deterministic, nothing to host.
