Turn your idea into a real app.

What is Capacity?

Capacity enables non-technical users to build production-ready applications simply by describing what they want in plain English. The platform asks clarifying questions, creates an implementation plan, generates the application, and allows users to continue refining it through conversation.

Capacity 3.0 introduced a built-in full-stack architecture with an Express backend, dedicated SQLite database, API routes, JWT authentication, and generated frontend code. Users own the generated code and can export it to GitHub or deploy it elsewhere, reducing vendor lock-in.

The platform supports websites, SaaS products, dashboards, e-commerce applications, booking systems, games, consumer apps, and native mobile applications. Web applications are generated with React, TypeScript, and Tailwind CSS, while mobile applications use React Native.

Capacity also offers Spec mode for planning an application before development, Vibe mode for faster conversational building, live previews, version history and rollback, templates, AI-assisted editing, custom domains, and one-click deployment.
