## What is Eurorack Planner?

Plan your Eurorack rack before you spend a single euro on a new module.

Eurorack Planner lets you drag real modules — in their actual HP width — onto a virtual rack, just like the real thing. Rearrange your layout, try out a new module before you buy it, and see instantly whether your power supply can actually handle it.

WHY THIS APP
Most rack planning happens in your head, on paper, or in a browser tab. Eurorack Planner is the first app built specifically to plan HP layout AND check your +12V / -12V / +5V power budget against your case's PSU — all before you order anything.

FEATURES
• Drag-and-drop modules onto HP-snapped rack rows — no gaps, no overlaps
• Live power budget: see exactly how much of your +12V, -12V and +5V rails you're using
• A curated catalog of well-known modules from major manufacturers, with real HP width and current draw
• Can't find a module? Add your own in seconds — HP width and per-rail current draw
• Multiple racks, so you can plan a small case and a full wall system side by side
• Export your rack layout as an image to share or save

PRO
Unlock unlimited racks and clean, watermark-free exports with a single one-time purchase — no subscription, ever.

Whether you're planning your very first 6U case or figuring out if that new oscillator will fit (and fit your power budget) in a rack that's already full, Eurorack Planner takes the guesswork out of growing your system.
