ADS-B Exchange started as (and still is) a group of aviation enthusiasts pooling their feeder data to provide the most complete picture of air traffic possible without the censorship present on the “large, commercial networks”.
ADSBx prefers to allow “free” access to as many features as possible.
Of course, if you enjoy using our site features, the community here would appreciate it if you shared your data. There are some features, such as enhanced map layers that incur extra cost, so are only available to feeders or subscribers.
