Best AI app builders: choose by the app you need to ship

OverSkill

OverSkill positions itself as a full-stack AI app builder with sign-in, database, payments and other product infrastructure available through the build workflow. Its current public pricing uses monthly AI credits, so builders should understand both generation usage and any live-app actions that consume credits.

Lovable

Lovable combines conversational app creation with a documented Supabase integration. Supabase can provide PostgreSQL data, authentication, storage, realtime features and edge functions. That can suit builders who like a clear external backend service and want to understand that relationship.

Bolt

Bolt's current product combines browser-based AI development with Bolt Cloud. Its official material describes hosting, domains, databases, authentication and payments, plus two-way GitHub sync. That makes it worth investigating when Git-based workflow and deployment flexibility are important.

Base44

Base44 targets prompt-driven full-stack app creation. Its current official pages say paid plans can export code to GitHub or as a ZIP, while importing an existing GitHub repository is not supported. That distinction matters if you already have a codebase.

How to compare them fairly

Build the same small project in your final two choices. Include sign-in, one saved record, a protected view and one change after the first build. Record how much manual setup was required, whether the generated app survived the change and what the real monthly cost would be.

A short practical test is more informative than a giant feature table whose rows do not matter to your product.
