How does Lovable work?
Last checked 31 Aug 2026
Short answer
You send a prompt, Lovable plans and writes real code files, runs the project, and shows you a live preview — repeating that loop for every change you ask for.
The build loop
- You prompt. You describe a page, a feature or a fix in plain language.
- Lovable reads the project. It looks at the files that already exist so new work matches what is there.
- It writes code. Components, routes, styles, database tables and server logic as required.
- It runs and checks. Build errors are caught and usually fixed before you see them.
- You review the preview. Then you prompt again.
Every change creates a version automatically, so you can revert if a step goes wrong.
The pieces you interact with
- Chat — where you describe work and answer clarifying questions.
- Preview — the running app, with a toolbar for selecting and annotating elements directly.
- Code — the actual files, searchable and editable.
- History — every version, with revert and bookmarking.
Build mode vs plan mode
In build mode Lovable implements changes end-to-end. In plan mode it discusses and plans first without touching your files — useful before a big or risky feature.
Where the backend comes from
Turning on Lovable Cloud gives the project a managed database, authentication, file storage and server functions, so features like logins and saved data work without you wiring up a separate service.
