📘 Overview of Capacity
👉 Summary
Vibe-coding — the trend of generating entire applications through AI conversational prompts — has its limits: the produced code is often fragile, hard to maintain, and locked into proprietary platforms. Capacity.so offers a structured response with a disciplined spec-first approach that produces production-ready TypeScript/Next.js code, fully exportable with no vendor lock-in. It's a tool built for developers, founders, and agencies who want AI efficiency without sacrificing code quality.
💡 What is Capacity?
Capacity.so is an AI-powered full-stack web app builder. Its distinguishing feature is its spec-first methodology: before generating any code, the platform guides users through writing a complete project brief and granular user stories. Its agentic engine then processes these specifications to generate coherent, business-logic-aligned, immediately deployable TypeScript code.
🧩 Key features
Capacity.so generates complete applications in TypeScript with Next.js for the frontend, Supabase for the backend and database, Tailwind CSS for design, and tRPC or REST APIs. Agentic Mode orchestrates the generation of the entire application in one session. Full source code export to GitHub or direct download guarantees complete intellectual property ownership. Higher plans include custom domains, dedicated support, and early access to new features.
🚀 Use cases
Capacity.so excels at rapidly scaffolding MVPs for startups or freelance projects. Agencies use it to produce client prototypes in record time. Solo developers accelerate the initial phase of personal or professional projects. Non-technical founders with a clear product vision can delegate initial code generation while retaining full control over the output.
🤝 Benefits
Capacity.so drastically reduces the time to scaffold a complete web application, from several days to a few hours. The quality of generated code, thanks to the spec-first approach, is superior to most vibe-coding tools. No vendor lock-in preserves users' technical freedom. The credit system means you only pay for what you use.
💰 Pricing
Capacity.so offers four plans: Starter at $25/month (100 credits), Growth at $69/month (250 credits, popular), Professional at $129/month (500 credits), and Enterprise at $299/month (1,000 credits). All plans include full Agentic Mode access. Additional credits can be purchased separately.
📌 Conclusion
Capacity.so is one of the most serious AI code generation tools thanks to its spec-first approach. For developers and founders who want to scaffold fast without sacrificing quality, it's an excellent choice. Full ownership of generated code makes it a trustworthy platform for professional projects.
