Capacity is an AI-powered web development platform that transforms ideas into production-ready web applications using a structured approach called Spec Coding. Instead of jumping straight into coding, Capacity helps users define their application specifications first before generating any code, ensuring clearer requirements and better outcomes.

Capacity generates production-ready React applications with Tailwind CSS, TypeScript, and tRPC/REST APIs. The platform features AI agents that understand context and make intelligent decisions across your entire codebase, multi-file refactoring with full dependency tracking, and automatic error and bug fixing without manual intervention. It provides advanced context awareness with deep understanding of project structure, patterns, and conventions.

The platform uses Spec Coding methodology, which involves a structured four-step approach: writing your project brief, defining user experience, specifying design requirements, and then having AI generate your code. This approach ensures AI understands precisely what to build rather than guessing from vague instructions.

Capacity enables faster development with clear specs meaning fewer iterations, predictable and consistent changes when updating specifications, and reduced risk by validating ideas in specifications before development investment. Users can go from concept to production in hours rather than weeks with better structured, more maintainable code architecture.

The platform serves as an AI cofounder that understands your vision, brainstorms ideas, writes production-ready code, and helps ship faster. It's designed for building various applications including analytics dashboards, property managers, course builders, and AI SEO writers without requiring coding skills.
