Plan stints, coordinate drivers, calculate fuel, and execute your race strategy — all in one place built for the pace of endurance sim racing.
Platform features
Built around the real workflow of an endurance race team — from prep week through to the final lap.
Hour-by-hour drag-to-select grid covering the full race window, including multi-day events. Auto-saves on mouse-up. The auto-planner only assigns stints during marked availability.
Press ⌘G (or Ctrl+G) to generate a complete stint schedule. The algorithm respects availability blocks, max stint duration, and fuel capacity — then previews the plan before applying.
Define pit stop types per event — set duration, fuel amount, and whether it's a driver swap. The auto-planner picks the correct type at every transition automatically.
Calculates exactly how many litres each stint needs based on the driver's avg fuel per lap and lap count. Tracks running fuel across the race — no unnecessary top-ups.
When the race goes live, the planner shows the active driver, remaining stint time, real-time fuel estimate, next pit time, and who's up next — synced across the whole team via Supabase Realtime.
Create a team and share a 6-character join code. Three roles — Owner, Strategist, and Driver. Owners manage members and events; everyone sees the same race plan.
Workflow
From creating your event to applying a complete stint plan takes less time than a formation lap.
Set race name, track, start and end time, and fuel capacity. Then define your pit stop types — driver swap, fuel-only, standard service — each with a duration and fuel amount.
Add drivers and enter their avg lap time, fuel per lap, and max stint length. Each driver then fills in their availability on the hour-by-hour grid — the planner uses this to constrain assignments.
Hit ⌘G (Mac) or Ctrl+G (Windows) to generate a complete plan. Preview coverage %, pit count, and pit loss before applying. Manually edit any stint at any time — auto-generated stints are just a starting point.
The planner switches to live mode automatically when the race starts. Current driver, pit countdown, fuel estimate, and next driver — all live. Any teammate with access sees the same real-time view.
Pit stop intelligence
Define your pit stop types once per event. StintForge automatically selects driver swap stops when the driver changes, fuel stops when the tank needs it, and calculates the exact litres needed — not a full tank, not a guess.

Endurance racing is won in the pits. Every second of unnecessary pit time, every litre of fuel added that you didn't need — it adds up over 24 hours. StintForge keeps your strategy tight.
