—flow
A prototype built in code is a link you click through. There is no overview, no way to reach the error state without walking the whole flow, and nowhere to leave feedback on it. —flow lays each flow out as a canvas of live screens. Every node is one screen in one state, rendered from fixed sample data, so a failure is one click away. Comments pin to the exact state and viewport. Missing states shows what a screen should have but doesn't yet. Interface built on Arc by Elia Kuratli. Trailbook is a fictional app.
