Frontend
Everything the user sees and clicks on.
What is Frontend?
The frontend is the visual part of your app — buttons, forms, pages, animations. It runs in the user's browser. Lovable and Bolt are primarily frontend tools. HTML, CSS, and JavaScript power the frontend.
When someone says a tool is "frontend-only," it means it builds the visual parts but doesn't handle databases, authentication, or payments on its own.
In Vibe Coding
Lovable and Bolt are primarily frontend tools — they excel at building what users see and interact with. Cursor handles both frontend and backend. When someone says an app is "frontend only," it means there's no database or server logic.
Example
For example: A landing page with a hero section, testimonials, and a contact form — that's all frontend. The moment you want to save form submissions to a database, you need a backend.
