Capacity

What Capacity is

Capacity is an AI development platform that builds full-stack apps from natural language. The site states it generates a React, Tailwind and TypeScript front end with an Express server and SQLite database, deployable to Vercel or AWS, and emphasises that you own the code and infrastructure.

What you can do with it

• Describe an app and get a full-stack build
• Deploy to Vercel or AWS
• Export and self-host the code
• Iterate on a working prototype

Who it is for

• Independent developers
• Small teams validating a product
• Founders wanting an exportable codebase

What to watch out for

• Production-ready is the vendor's claim; business logic, permissions, payments, security, error handling and performance still need review
• A generated Express and SQLite setup is fine for a prototype and usually needs replacing before real traffic
• Deploying to your own cloud account means you own the bill and the security configuration
• Complex or compliance-heavy systems need engineering experience
