Capacity vs Lovable

What is Capacity?

Capacity is an AI-driven development platform designed to bridge the gap between natural language descriptions and production-ready applications. Unlike many AI code generators that focus solely on frontend components, this tool builds full-stack environments including a dedicated Express backend and a SQLite database for every project. Users interact with an AI "Co-founder" to articulate their vision, which the platform then translates into a functional web application or a mobile app using React Native.

What is Lovable?

Lovable is an AI-powered development platform designed to streamline the creation of full-stack web applications and websites through a conversational interface. Unlike traditional no-code tools that rely on manual drag-and-drop mechanics, this platform allows users to build and iterate on software by simply describing their requirements in natural language. The system interprets these instructions to generate clean code and functional components, effectively bridging the gap between conceptual design and production-ready deployment.

Who Capacity is for

• Solo founders can rapidly build and launch a full-stack MVP with a working backend and database to validate business ideas.
• Non-technical business owners can describe their workflow to create custom internal tools and dashboards without hiring a developer.
• Product managers can use Spec mode to generate detailed technical requirements and visual prototypes for stakeholder approval.

Who Lovable is for

• Founders can build and ship a Minimum Viable Product (MVP) in days rather than months by describing features to the AI.
• Product Managers can turn design mockups into interactive, clickable prototypes for more effective stakeholder presentations.
• Designers can create functional web versions of their visual designs without needing to write manual CSS or HTML.

Capacity features

• Custom domain support
• Multi-model AI switching
• Full-stack code generation
• Agentic coding assistant
• AI spec planning mode
• Export to github
• Integrated sqlite database
• React native mobile support

Lovable features

• Extensive template library
• Single sign-on (sso)
• Role-based access controls
• Custom domain integration
• Real-time visual prototyping
• Screenshot-to-code conversion
• One-click cloud deployment
• Chat-based app generation

Capacity strengths

• Complete code ownership with no vendor lock-in via full codebase exports.
• Provides a real backend and database for every app rather than just frontend templates.
• Credits never expire, allowing for flexible development timelines without losing value.
• Spec mode enables thorough project planning and architectural mapping before building.

Lovable strengths

• Generates functional full-stack code from simple natural language prompts.
• Allows users to build UI layouts instantly by uploading visual screenshots.
• Includes built-in hosting and infrastructure management for immediate deployment.
• Offers a free forever tier that supports unlimited collaborators.

Capacity limitations

• Credit consumption is variable and depends on task complexity, which can make costs unpredictable.
• The core database option is limited to SQLite, which may not suit all enterprise needs.
• Codebase export functionality is locked behind the higher-tier Growth plan.
• Technical documentation and community resources are still evolving as a newer platform.

Lovable limitations

• Projects created on the Free tier are restricted to being public to the community.
• The daily credit limit on the Free plan can restrict rapid iteration for large projects.
• Removal of the platform's branding badge requires a paid Pro subscription.
• Advanced internal publishing and SSO are only available on the Business tier and above.
