Build real apps, not just prototypes

A prototype shows the idea. A real app runs the workflow. Base44 helps you create apps with screens, data, backend logic, authentication, permissions, integrations, and deployment — all from one platform.

Create your appCreate your app

Create the app interface

Generate the screens your app needs, from dashboards and forms to portals, admin panels, and user flows. Start with AI, then refine the experience as your product takes shape.

Add backend logic

Define what happens when users submit forms, update records, trigger actions, or move through a workflow. Add the rules and logic that make your app functional, not just visual.

Launch and share instantly

With free web hosting included, your app is ready whenever you are. Publish, test and share it with users, teammates or your community without dealing with setup or deployment.

Security built into every app

Base44’s built-in Security Scanner acts as a first line of defense, identifying common vulnerabilities early in the build process so your app stays protected from the start.

Get started with an app template

Choose a ready-made app design template, then customize the screens, data, workflows, and logic with Base44. Start from a proven structure instead of a blank prompt.

AI app builder FAQs

An AI app builder is a platform that lets you create fully functional apps using plain language — no coding required. You describe what you want, and the AI handles the design, logic, database, and backend automatically. Traditional app development requires a team of developers, months of work, and tens of thousands of dollars. An AI app builder removes all of that — anyone can go from idea to working app in minutes.

Think it. Prompt it. Launch it.
