F* is a programming language with proof support. Lean/Coq are theorem providers that can be used to model and generate code. In Coq, there's not a standard way to generate code, you might model and create code many different ways. F* seems to bring this in as the central goal of the language. So I'm discussing this structural difference. F* has an SMT solver, but Lean can import an SMT solver. So the goal is the important difference here - making theorem proving as accessible as possible in a real language. It's a move in the right direction, but we want to get to the point standard program languages have this support if you need it.
