- Limited to web applications only
- Credit-based pricing at $25/month for 25K credits
Floot Review Summary
Floot has gained traction with over 3,000 users creating 4,000+ apps since its launch. The platform excels at rapid prototyping through its conversational interface and unique visual drawing editor that lets you circle elements to modify them.
However, Floot's approach has significant limitations for serious application development. The custom proprietary framework means your code isn't using industry-standard tools, making it harder to hire developers or migrate to other platforms. The lack of GitHub integration means no version control, branching, or collaboration features that professional teams expect.
For quick prototypes and non-technical founders, Floot can be a good starting point. But for applications that need to scale, maintain code quality, and support professional development workflows, Capacity's spec-first approach provides a more sustainable foundation.
Why Choose Capacity Over Floot
Capacity offers a fundamentally different approach to AI-powered development that produces better results for production applications.
Spec-First Methodology
While Floot jumps straight to code from prompts, Capacity builds comprehensive specifications first. This means your project brief, UX specs, design system, and user stories are all defined before a single line of code is written, resulting in more accurate implementations.
Native GitHub Integration
Floot has no GitHub integration, limiting version control options. Capacity provides native GitHub integration for full version control, branching, collaboration, and CI/CD workflows that professional development teams expect.
Open Standards, Not Proprietary
Floot uses a custom proprietary framework that isn't open source. Capacity generates standard Next.js, TypeScript, and Tailwind CSS code that works anywhere, can be maintained by any developer, and integrates with the broader ecosystem.
Native Supabase Integration
Capacity integrates natively with Supabase, giving you PostgreSQL database, authentication, real-time subscriptions, and edge functions. Floot has its own built-in database, but it locks you into their ecosystem with less flexibility.
How Capacity Works
A structured approach that produces better results than conversational AI building.
Project Brief
Start by defining your project goals, target audience, and key features. The AI Co-founder helps refine your vision.
UX Specifications

Design System
Establish colors, typography, spacing, and component styles that ensure consistency across your app.
User Stories
Break down features into implementable user stories with clear acceptance criteria.
Code Generation
AI generates production-ready code based on your detailed specifications, with GitHub integration.

Frequently Asked Questions
Common questions about Capacity vs Floot
What makes Capacity different from Floot?
The fundamental difference is methodology. Floot uses conversational AI where you describe what you want and AI generates it immediately with visual drawing for refinements. Capacity uses spec-first development where you define detailed specifications (project brief, UX, design, user stories) before code generation. This results in more accurate, maintainable code that matches your exact requirements and creates living documentation.
Is Floot good for building production apps?
Floot can build functional web applications and offers production-grade hosting. However, its conversational approach lacks the structured planning that complex applications need. Capacity's spec-first methodology ensures every feature is planned, documented, and reviewed before implementation, reducing bugs and technical debt.
Can I export code from Floot?
Yes, Floot allows code export and you retain full ownership. However, Floot uses a custom proprietary framework that isn't open source. Capacity generates standard Next.js, TypeScript, and Tailwind CSS code that works anywhere and integrates directly with GitHub for version control and CI/CD.
Which platform is better for startups?
It depends on your stage. Floot is great for quick prototypes and non-technical founders who need something working fast. Capacity is better for startups building production applications that need to scale, maintain code quality, and have clear documentation for investors and future developers.
Does Capacity support payment processing like Floot?
Yes, Capacity supports payment processing through Supabase and Stripe integration. While Floot has built-in payment processing, Capacity's approach gives you more control and flexibility, plus you own the integration code completely.
How does pricing compare between Capacity and Floot?
Both offer free tiers. Floot's Pro plan is $25/month with 25K credits. Capacity has a generous free tier to start building, with flexible pricing that scales with your needs. Capacity doesn't use a credit-based system that creates anxiety about running out mid-project.
What about the visual drawing feature in Floot?
Floot's drawing feature lets you circle elements and draw arrows to indicate changes. While intuitive for simple edits, this approach becomes limiting for complex applications. Capacity uses detailed specifications and direct code editing, giving you precise control over every aspect of your application.
Can I migrate from Floot to Capacity?
Yes, you can migrate from Floot to Capacity. Export your Floot project and use it as reference when creating specifications in Capacity. Since Capacity generates standard code, you'll end up with a more maintainable codebase that integrates with professional development workflows.
Which has better version control?
Capacity has native GitHub integration for full version control, branching, and collaboration. This means you can track every change, roll back when needed, and collaborate with other developers. Floot doesn't offer GitHub integration, limiting version control capabilities.
Who should use Floot vs Capacity?
Use Floot if you're a non-technical entrepreneur who needs a quick prototype and prefers visual/conversational interaction. Choose Capacity if you're building a serious application that needs to be maintainable, well-documented, and ready for professional development workflows.
What's the difference in tech stack?
Floot uses a custom proprietary framework (Node.js/React/TypeScript) that isn't open source. Capacity generates standard Next.js with TypeScript and Tailwind CSS, integrates with Supabase for the database, and produces industry-standard code that any developer can work with.
Does Floot have an AI co-founder feature like Capacity?
No, Floot focuses on conversational building and visual editing. Capacity's AI Co-founder helps you think through your product strategy, refine your specifications, and make better architectural decisions before writing any code.
The Bottom Line
Floot is great for non-technical entrepreneurs who want to quickly prototype ideas through conversational AI and visual drawing. Its Y Combinator backing and autonomous error fixing make it accessible for beginners.
Capacity is built for serious builders who want production-ready applications with comprehensive specifications, native GitHub integration, open-source tech stack, and living documentation. If you're building something that needs to scale and be maintained by a team, Capacity's spec-first approach provides the foundation for long-term success.
