Cloud: Backend and Database

The magic of having an app that not only builds UI but also connects all the pieces to a database and backend logic. This is the most powerful feature of Capsule. Every new app you create can get this integration by enabling the cloud option. After enabling it the code agent knows and creates fullstack apps always for you from there on.

Voice Prompting

Vibe coding with your voice sets you free to very easily express your ideas, jump into the flow and let go.

Visual Edits

Hovering and pointing at the visual element you want to change enables easy prompting. There is no need to tell the agent where to make changes, only what to change.
