About Capacity
Capacity is a credit-based AI development tool that turns plain-language ideas into full-stack web applications, positioning itself as an “AI cofounder” for founders, indie hackers, and product teams. It focuses on specification-driven development through its Spec Coding workflow, where users define a project brief, UX, and design requirements before the AI generates production-ready code. The platform produces modern web apps using technologies such as Next.js, React, TypeScript, Tailwind CSS, and Supabase, and supports both quick “vibe coding” experiments and more rigorous production builds. Capacity’s Spec Coding methodology is structured, specification-first flow (brief, UX, design) so AI generates code that follows clearly defined requirements instead of guessing from vague prompts. The AI Cofounder workspace helps brainstorm ideas, refine concepts, and translate them into scoped features and coding tasks, keeping product vision and implementation aligned. True agentic coding allows project-aware AI agents to understand the codebase, support multi-file refactors with dependency tracking, and automatically fix many errors and bugs across files. Capacity’s full-stack generation builds database-backed apps with auth, storage, and real-time updates on top of Supabase, along with frontend and backend code in a production-ready stack. Every interaction with the AI uses credits based on task complexity, which lets users scale usage from quick tests to large projects without changing tools. Users can export the entire codebase, connect GitHub, and still rely on Capacity’s managed hosting when they do not want to run infrastructure themselves.
Key features
- Spec Coding methodology for structured development
- AI Cofounder workspace for brainstorming and concept refinement
- True agentic coding with project-aware AI agents
- Full-stack generation of modern web apps
- Credit-based workflow for scalable usage
- Code export and hosting options
Use cases
- Solo founders and indie hackers validating SaaS or marketplace ideas quickly
- Startup product teams spiking features, building internal tools, and iterating on product experiments
- Agencies and studios producing client MVPs, dashboards, and custom CRMs faster
Pros
- Turns plain-language ideas into full-stack web applications using modern stacks like Next.js, React, TypeScript, Tailwind CSS, and Supabase
- Uses a specification-first workflow (brief, UX, design) to generate production-ready code aligned with defined requirements
- Supports agentic coding with project-aware AI agents that understand the codebase, handle multi-file refactors, and track dependencies
- Enables both quick prototyping and rigorous production builds with credit-based usage scaling from tests to large projects
- Provides managed hosting and allows codebase export or GitHub integration for flexibility in deployment
Cons
- Requires upfront specification input (brief, UX, design) which may slow down spontaneous or highly experimental development
- Credit-based pricing model may become costly for large or complex projects without clear cost predictability
- Dependency on AI-generated code may introduce unexpected issues requiring manual review or debugging
- Limited customization for users who prefer low-code or no-code solutions over specification-driven development
Frequently asked questions about Capacity
What is Capacity and who is it designed for?
Capacity is an AI-powered development platform designed to turn plain-language ideas into full-stack web applications. It serves founders, indie hackers, and product teams looking to accelerate development with AI-driven workflows.
How does Capacity generate production-ready code?
Capacity uses a specification-driven approach called Spec Coding, where users define project briefs, UX, and design requirements. The AI then generates production-ready code based on these structured specifications.
What technologies does Capacity use for app development?
Capacity builds modern web apps using technologies such as Next.js, React, TypeScript, Tailwind CSS, and Supabase, ensuring a production-ready stack for both frontend and backend.
Can Capacity handle multi-file refactors and dependency tracking?
Yes, Capacity supports project-aware AI agents that understand the codebase, perform multi-file refactors, and track dependencies to automatically fix errors and bugs across files.
Does Capacity support database-backed apps with real-time updates?
Yes, Capacity generates database-backed apps with authentication, storage, and real-time updates using Supabase, providing a complete backend solution.
How does Capacity's pricing model work?
Capacity operates on a credit-based system where each interaction with the AI consumes credits based on task complexity. This allows users to scale from quick tests to large projects without switching tools.
