10 years on Steam. 17 years of building setup tools for sim racers.
onRails is our biggest release yet — combining and replacing both Virtual Race Car Engineer and Setup Developer Tool into a single, redesigned app.


What’s New

Transparent Overlay

Runs on top of your sim. No alt-tabbing. No second monitor required.

Two Tools in One

The Setup Developer builds your baseline. The Setup Engineer tunes it lap by lap.

Direct Sim Integration

Auto-detects your sim and reads tire temps and lap times live from six supported simulators.

In-Race Engineer

A first-of-its-kind keyboard assistant that gives you pit-call setup recommendations while you’re driving.
