// PRIVATE BETA

Your system is an instrument,
not furniture.

RackJam is a system planner for Eurorack. Design your racks as living schematics — every jack, knob and signal path — with power, depth and price computed honestly as you build. Alone, or live with a friend.

The planner is invite-only while we wire the beta. The waitlist is the queue.

01 · DESIGN VIEW

Schematics, not photos

Every module is a semantic panel — jacks typed by signal, knobs and sliders addressable. Zoom out and your rack reads as an instrument architecture, not a wall of faceplates.

02 · ENGINEERING-HONEST

Power, depth, price — live

Rail draw against your PSU budget, per-position depth, real cost including the modules you only wish you owned. The summaries update with every move, and they never flatter.

03 · CO-EDIT LIVE

Build together, in realtime

Invite a friend into your system and plan side by side — live cursors, shared history, one document. Built for the way modular people actually scheme.
