Card prototyper

The card prototyper turns a table of data into a deck of designed cards. Add columns for the values that change from card to card — names, costs, art, rules text, stats — and lay them out once on the canvas. Every row becomes a card that reuses the same layout, so a hundred cards take no more work than one. It is built for game designers who need to test ideas on the table fast, without wrestling a spreadsheet into a graphics editor.

Bind text and image elements to your columns, or drop in static art that repeats on every card. A bound element pulls its content from the current row, so a single "Name" field fills in automatically across the whole deck; a static element — a frame, a logo, a background — stays fixed on every card. Position items freely in millimeters, set fonts, colors, outlines, and alignment, and let text auto-shrink to fit its box so long names never overflow.

Import your data from a CSV or build the table directly in the tool. Columns are auto-detected as text or image, and image cells resolve against an asset library so the right artwork lands on the right card. You can upload your own images, link external URLs, or generate placeholder art while you iterate on the design.

When the layout looks right, jump to the deck view to review the full set at a glance, or to the print sheet to arrange everything for cutting. Nothing is uploaded to a server — the prototyper runs entirely in your browser, saves locally, and exports printable files whenever you are ready for a physical playtest. It is a free, fast way to go from a rough idea to a deck you can hold in your hands.
