They’re not the same kind of thing. Tradovate is a cloud-based futures broker and trading platform that executes your orders. ProjectX is a platform front-end (now reaching traders as TopstepX) that sits over broker infrastructure such as Rithmic.
Tradovate is the brokerage that actually fills your orders, with web, mobile and desktop apps used by many prop firms. ProjectX is an interface engine — integrated TradingView charts and drag-and-drop brackets in the browser — that moved to an exclusive arrangement with Topstep, so in practice it now appears as TopstepX. (Business arrangements change; confirm the current status directly.) A prop firm usually offers one of them as the interface to your funded account.
"ProjectX vs Tradovate" is partly apples-to-oranges. The friction shows up when your accounts span both worlds — common once you fund with more than one firm — because you end up switching between a Tradovate app and a TopstepX tab.
