How Building Works
What happens between pressing Send and having a finished build — the same shape for every build type.
The flow
Plan or Build
The composer opens in Plan: a conversation about the approach, with nothing built yet. When the plan looks right, choose Build it. Switch to Build to skip planning. Planning is the cheap place to change your mind — a build is not.
The engine is chosen by the build type
The build type sends your description down one of four engines, and that decides what the result is: a validated specification rendered into a site, a self-contained interactive program, a React Native project, or a 3D game definition. Switching type means a new build, not a conversion. See Build Types.
What you see while it runs
Each stage appears as it starts and finishes, with skipped stages marked — for example, Lite skips photographs. The stages are listed on each build type’s page and in full in the Generation Pipeline.
