Zwift is a Long Beach, California online fitness company that operates a multiplayer indoor cycling and running platform combining stationary smart trainers and bikes with a 3D virtual-world game client. Riders and runners use a smart trainer, smart bike (such as the in-house Zwift Ride), treadmill, or pod to drive an avatar through fictional worlds (Watopia, Makuri Islands) and licensed real-world routes, joining structured workouts, group rides, races, training plans, and 24/7 events alongside a global community of more than a million members. The platform pairs with smart trainers and heart-rate monitors over Bluetooth and ANT+, and the Zwift Companion mobile app provides in-game messaging, ride control, and route discovery. Zwift does not operate a general public developer portal, OpenAPI reference, or open-source SDK. Its developer surface is limited to a private, application-only Structured Training API for approved training partners (TrainingPeaks, TrainerRoad, Wahoo SYSTM, JOIN Cycling and similar coaching platforms) that lets external workout builders push custom workouts into a rider's Zwift account, plus one-way activity-export connections to Strava, TrainingPeaks, Garmin Connect, MapMyRide, MapMyRun, Adidas Running, Technogym, Fitbit, Wahoo, Apple Health, and Withings. There is no public REST surface, OAuth client registration, or partner self-service available to general developers — third-party tools (community libraries, ZwiftPower, Sauce for Zwift) interact with Zwift via reverse-engineered private endpoints, not a sanctioned API. Zwift is a paid consumer subscription business; revenue comes from monthly memberships and hardware sales (Zwift Ride, Zwift Cog, Zwift Click, Zwift Play).
