PitLane includes 10 overlays — 5 production-grade Advanced Broadcast overlays and 5 simple templates. All are served as web pages from PitLane's built-in overlay server and displayed in your stream via OBS browser sources.
Managing overlays
Go to the Overlays panel in PitLane (enable via View > Overlays if hidden).
- Add Overlay — click the add button to browse available overlays and add them to your active set
- Toggle on/off — each overlay has a switch to enable or disable it. Disabled overlays stop receiving data.
- Controls — click an overlay to expand its inline controls. Click the gear icon for additional settings.
- Remove — remove an overlay from your active set (this doesn't delete it, just hides it from the panel)
Only overlays in your active set receive live data and appear as iframe previews in the program monitor.
Advanced Broadcast overlays
These are production-grade overlays built for broadcast use. They share a consistent dark visual style with the Teko font for names and JetBrains Mono for data.

Template overlays
These are simple, single-file HTML overlays designed to be easy to understand, customize, and fork. They have no configurable controls — what you see is what you get.
| Overlay | URL | What it shows |
|---|---|---|
| Timing Tower | http://localhost:9100/overlay/leaderboard | Basic position list with gaps |
| Lower Third | http://localhost:9100/overlay/lower-third | Driver name and position card |
| Battle Graphic | http://localhost:9100/overlay/battle | Simple gap display between two cars |
| Session Info | http://localhost:9100/overlay/session-info | Track name, session type, time remaining |
| Event Ticker | http://localhost:9100/overlay/ticker | Scrolling feed of race events |
Template overlays are a good starting point for building Custom Overlays.
Overlay theming
All Advanced Broadcast overlays support an Accent Color setting that tints key visual elements (position highlights, borders, data emphasis). You can set this per-overlay or use the global theme to apply one color to all overlays at once.
The global theme controls are in the Overlays panel header — click the palette icon.
