Design a template once in the visual editor, then render unlimited variations by sending JSON with your text and images.
Use cases: blog thumbnails, certificates, social posts, invoices, receipts, or anything that needs the same design with different content.
How it works:
Drag-and-drop editor to design your template
POST request to modify any layer (text, images, shapes)
Get back production PNG/JPG/WebP(thinking about adding PDF in the nearest future)
Supports bulk generation from spreadsheets
Built with React, Node, and headless Chromium for pixel-perfect renders. Getting sub-second render times with Chromium took some work.
