Locodex is a small ecosystem for the model railroad bench — a precision track planner and a reference encyclopedia, sharing one account.
PlannerLive
A drafting table for track. Drag real Märklin, Kato, Hornby and Jouef pieces onto your baseboard — snap geometry refuses anything that can't be built.

Why Locodex
Made for the hobby, not off it.
Fair pricing
Pay once for what exists, optional upgrades for what's genuinely new. No subscription traps, no punishing the infrequent user.
Offline-first
Install it and it works on the bench, on the train, off the grid. The cloud is a convenience, never a requirement.
