Otranspo is an independently owned and operated transit information service created by an Ottawa–Gatineau resident. It helps riders find nearby, saved, or searched stops and compare live transit predictions with scheduled service across the region. Users can look up stops, browse stations, view departures, and plan trips.

The service also provides access to route and station information, service alerts, service reports, and updates on whether the O-Train is running. Riders can explore transit options for events and plan journeys in both directions. Location sharing is optional: users may provide their coordinates to find nearby stops or search by stop or place instead.

Otranspo also presents weather information sourced from Open-Meteo and offers tools to share a permanent public link to the page. Its website includes rider guidance, methodology, data-source and licensing information, corrections, accessibility details, privacy and security policies, and contact information. Otranspo is designed as an independent resource for navigating public transit in Ottawa and Gatineau
