Quilt design software turns a rough idea into a finished, buildable plan. Instead of sketching on graph paper, you tile blocks into a layout, audition real fabrics, and let the software work out exactly how much fabric to buy and how to cut it. Quiltler does all of that on the desktop in your browser — and a companion app keeps every project in sync on iPhone and iPad.

What quilt design software does
At its core, quilt design software (sometimes called quilting software or quilt pattern design software) lets you plan a quilt digitally before you cut a single piece of fabric. The best programs go well beyond drawing:
- Build blocks and layouts from a library or from custom shapes you draw yourself.
- Audition fabrics so you can see how colors and prints read together at real scale.
- Calculate yardage and cutting automatically from the design's true geometry.
- Export print-ready instructions — a shopping list, cutting chart and assembly guide.
That combination is what separates a serious design tool from a simple coloring app, and it's exactly what Quiltler is built to do.
Design on desktop, with a companion app
Quiltler is desktop quilt design software first. You can design a quilt online in any modern browser with nothing to install. When you want the same studio on the go, the companion app for iPhone and iPad adds touch and Apple Pencil. Your quilts, fabrics and custom cuts sync automatically, so you can start at your desk and finish on the couch.
No download required: Open the Quiltler designer in your browser and build your first block in minutes, or get the free companion app.

Quilt design software vs. traditional desktop programs
Long-established desktop programs like Electric Quilt 8 are powerful and have huge block libraries, but they only run as a Windows or Mac install. Quiltler is also a desktop studio — it runs in the browser on any computer — and a companion app lets you keep designing on iPhone or iPad. You get automatic yardage, your own fabric library, custom shapes and an editable marketplace without being locked to one machine.
