Hey Product Hunt 👋 I love F1 but most "F1 simulator" results are either expensive sim rigs or console games. I wanted something you can open in a browser tab and actually make racing decisions in: tyre calls, when to box, whether to pit under the safety car. So GrandPrixSim is a set of small games on one race engine: 🏁 Race Sim: set up, qualify, then run the race from the pit wall 🧒 Career: an eight-year-old karter climbing F4, F3, F2 into F1, where money matters as much as talent 🏆 Season Sim: all 24 rounds, or run a team as principal with development budgets and a driver market 📊 Tools: race predictor, title calculator on the real 2026 standings, pit strategy and lap-time sims The hardest part was the engine. My first version re-sorted the field by lap time every lap, so fast cars teleported past slower ones and grid position meant nothing. Now track position only changes by overtaking, pitting or retiring. Start last at Monaco and you'll finish around P14; at Monza you can fight back to around P8. Everything saves in your browser. No account, no ads wall. I'd love feedback, especially from F1 fans: what feels wrong about the racing? Which decision would you want to make that you can't?
