Orb

Beta

Local, self-hosted Pit Wall Strategy, Stint and Team Management

Race tab during a 36 hour race, showing the pit call, fuel on board, the current stint, the next stop and the live track map

Orb runs a small server on one laptop, and any phone, tablet or TV on the same Wi-Fi sees the same live screens. Every second it recomputes the pit call, learns the real fuel burn and keeps the race plan legal against the series rules, while tracking driver rotation and rest. It needs no internet, cloud account or subscription.
