AI app builders

What it is

An AI app builder turns a plain-language brief into a running application: interface, logic and often a database. You iterate by asking for changes instead of writing code.

How it works

1. Describe the app, its users and the main screens.
2. The builder generates code and a live preview; you request changes in chat.
3. Connect data sources and publish, or export the code to a repository for developers to continue.

Lovable runs an MCP server (mcp.lovable.dev) on all plans, so an outside AI agent can create projects, inspect code and deploy; sensitive project scopes need Business or Enterprise. Usage runs on credits that pay for building, hosting and AI features, and unused monthly credits expire after two months.

Benefits

• Prototypes in hours instead of weeks.
• Business teams can build internal tools without waiting for engineering.
• Code export avoids being trapped in the builder.

Limits and risks

• Generated apps may have security gaps; review authentication and data access.
• Complex logic gets harder to steer through chat alone.
• Hosting, database and usage costs can grow with traffic, and credit costs vary by task.
• Plan names, prices and feature limits change often. This category page re-checks every 90 days; each tool page carries its own review date.
