AI app builder that turns a prompt into a full-stack Next.js app with database, auth, hosting and admin panel.

## Overview

Totalum is an AI app builder that turns a prompt into a full-stack Next.js app with its own database, authentication, hosting and admin panel. Generated projects can be downloaded.

The same builder is available through an API and an MCP server, so other AI agents and white-label builders can build apps with it. The client app is open source under the MIT license, while the coding agent, sandboxes, hosting and database run through Totalum’s paid API.

There is a free plan, with paid plans from €29 to €299 or more a month. API usage is billed at $0.07 per credit.
