Race control

See every pass, crash, and pit stop as it happens.

The event feed logs the race while you commentate. Click any entry and the replay jumps back to it on the camera of your choice — no scrubbing through the timeline while the field is under caution.

  • Click a driver to put the iRacing camera on them
  • Replay transport: slow motion, frame step, rewind, jump to live
  • Camera groups with saveable hotkey profiles
  • Global hotkeys for anything you would reach for a mouse to do
The event feed listing passes, a crash, a caution flag and pit stops by lap, with filter buttons for each event type and a replay camera selector.

Broadcast graphics

Graphics that fire themselves.

A timing tower that sorts on real on-track progress, so a pass shows the moment it happens. Stage results, race results with points, pit reports, and the starting grid — triggered from the launcher or automatically at the right lap.

The starting grid overlay showing the front row with driver names, car numbers, helmets and manufacturer logos.

01

Live timing tower

Eight switchable data columns — gap, interval, manufacturer, positions gained, last lap, best lap, pit lap, speed. Two visual packages and six color schemes.

02

Automatic race graphics

Stage results slide in as drivers cross the line. Race results carry a full points breakdown. The pit report tracks stall times and positions gained.

03

One OBS source

Every overlay is served from a single browser-source URL. Set it up once, then refresh everything from the launcher with one button.

04

Race history

Every completed race is saved with results, stage points, laps led and bonus points, so you can go back to any night of the season.

Built for race night

Know it's working before you go live.

The launcher starts its own local servers and shows their health at a glance. If the data server drops it restarts itself, and if the interface ever crashes it reloads without taking the servers down. Demo mode runs a scripted race so you can build your OBS scenes without iRacing open.

The Servers tab showing broadcast health: both local servers running, the iRacing feed connected, and the current race session.

Get started

Ready for race night.

$5 a month, $30 for six months, or $60 a year. One subscription activates two machines, and it keeps working offline for a week if your connection drops, so a bad network never stops a show.
