What irDashies Does
At its core, irDashies is a widget-based overlay system. Each piece of race data gets its own widget, and you can enable or disable each one independently through an on-screen toolbar. Every widget is draggable, resizable, and has its own settings panel you can open by double-clicking it. The layout saves automatically, and nothing is locked in place.
The widgets most drivers use most are the expected ones. Standings shows the full grid with car numbers, driver names, iRating, and live gap data. Relative shows the cars immediately around you on track, which is the widget you’ll actually glance at mid-session. The Fuel Calculator tracks consumption lap by lap and projects how many laps remain on your current load, which removes most of the mental math from endurance stints. The Lap Time Log records sector splits and gives you a consistent reference for pace tracking across a session.
The full widget library also includes a Track Map, Flat Track Map, Input Trace, Tachometer, Weather readout, Info Bar, Pitlane Helper, and Rejoin Indicator. Two proximity alerts round things out: Faster Cars Behind fires when traffic is closing from behind, and Blind Spot flags cars in the zones your mirrors don’t cover. Slow Car Ahead handles the other direction, giving you warning before you’re already on top of traffic.
Layouts and Customization
irDashies supports saved layouts through a Dashboard Profiles system. You can build separate configurations for oval, road, and endurance racing and switch between them without rebuilding anything. Each profile stores widget positions, sizes, and individual settings.
The customization goes deeper than placement. The app ships with 18 built-in color themes, per-widget background opacity controls, and adjustable font sizes and weights. If you want the standings overlay transparent and the fuel calculator fully opaque while keeping a clean broadcast look, that’s a few setting changes. Global keyboard shortcuts let you toggle the full overlay, lock widget positions, and capture telemetry data from inside the sim without alt-tabbing out.
Setup Compare
One of the standout tools outside the core overlay is Setup Compare. It lets you snapshot your current car setup, then load a second configuration to compare both versions side by side, showing exactly what changed between the two. For drivers who run back-to-back practice sessions and want to isolate what affected lap times, this is significantly faster than manually reviewing setup files.
Driver Tags
Driver Tags let you flag individual drivers with custom labels such as friend, streamer, or dangerous, and you can create your own groups too. Those tags show up in the standings and relative widgets during sessions so you always have context on who is around you on track. If you run a regular league or frequently encounter the same drivers in lobbies, this keeps relevant information in front of you without needing to look anything up mid-race.
For Streamers
irDashies was built with broadcast setups in mind. Every widget generates its own browser source URL, which means you can pull individual widgets directly into OBS or Streamlabs as separate layers. Standings in one scene, relative in another, fuel calculator always visible but positioned differently depending on the context. No desktop capture is required and no screen region cropping needed.
There’s also a built-in Twitch chat overlay with full emoji support. You can keep an eye on your stream from inside iRacing without switching windows during a session, which matters when you’re racing and can’t afford the distraction of alt-tabbing.
Free and Open Source
irDashies is free to download and released under the MIT License. The full source code is on GitHub, and the development community runs through a Discord server where bug reports, feature requests, and general support happen in the open. Auto-updates are built in, so staying current after install doesn’t require manual downloads or checking release notes.
How to Get It
irDashies is available at irdashies.com. The homepage includes an interactive demo that lets you toggle and reposition widgets before you download anything, so you can get a feel for how the layout system works first. Installation is straightforward, and the app connects to iRacing automatically when a session starts. If you’re running the sim without any overlay right now, this is the most capable free option available and a sensible place to start.
