At a glance
Webull and Horizon are not either-or. Webull is the broker: commission-free stocks, ETFs and options, desktop charting, and a paper-trading simulator that covers several asset classes. Horizon is the automation that runs inside a Webull account: a strategy you describe in plain English, or one you copy from a creator, that places its own trades through the login you authorise. This page compares what each does on its own.
