App Builder
Build your own app in minutes with AI.
App Builder: AI-Powered Web Application Generator with Real-Time Preview Build production-ready web applications through natural conversation with advanced AI technology. App Builder transforms your ideas into functional interactive web apps instantly featuring live preview panels and streaming responses for real-time development feedback. Transform text descriptions into complete applications including landing pages, dashboards, e-commerce platforms, portfolio sites, chat applications, todo apps, calculators, blog platforms, and custom business tools. The conversational interface understands complex requirements and generates clean modern code in real-time without requiring programming knowledge. Real-time streaming architecture provides instant feedback as your application takes shape. Split-screen interface displays chat history alongside live preview panels allowing immediate testing and iteration without switching contexts. Watch your application build itself as you refine requirements through natural language prompts and see changes apply instantly. Multi-modal input support accepts text descriptions and image attachments for visual reference. Upload design mockups, screenshots, wireframes, or inspiration images to guide the AI generation process with precise visual context. Drag and drop images directly into the prompt input for seamless workflow integration. Anonymous access allows immediate experimentation with three messages daily and no registration required for quick testing. Guest accounts provide five messages daily with session persistence for ongoing projects. Registered users receive fifty messages daily with permanent data storage across all devices and sessions for serious development work. Advanced AI capabilities include comprehensive task support covering code generation and editing, web search integration for current information, repository analysis and codebase search functionality, diagnostics and automated issue detection, file reading operations, and design inspiration generation. The AI handles thinking processes transparently showing reasoning steps throughout development so you understand how decisions are made. Built on Next.js 15 with React 19 for maximum performance and modern web capabilities. PostgreSQL database with Drizzle ORM ensures reliable data persistence and efficient queries. Multi-tenant architecture maintains user isolation and data security through ownership mapping preventing unauthorized access to projects. Rate limiting protects system resources while ensuring fair access across user tiers. IP-based tracking manages anonymous usage patterns. Authenticated users benefit from increased quotas and persistent project storage with automatic chat history saving and retrieval across sessions. Experimental streaming mode delivers real-time updates through server-sent events technology. Watch components render, styles apply, and functionality emerge as the AI processes your requirements live. Toggle between streaming and synchronous modes based on preference and network conditions for optimal experience. Modern tech stack includes TypeScript for type safety and better code quality, Tailwind CSS version 4 for responsive styling and design consistency, Radix UI primitives for accessible component foundations, and SWR for efficient data fetching and caching. Syntax highlighting with Shiki and React Syntax Highlighter makes code review effortless and professional. Full-featured prompt input with integrated toolbar, image preview capabilities, microphone support for voice input and speech recognition, and drag-and-drop file handling for images and assets. Auto-save functionality preserves your work in session storage preventing lost progress from browser refreshes or accidental navigation. Use cases include rapid prototyping for product validation without writing code, quick MVP development for startups and entrepreneurs testing business ideas, landing page generation for marketing campaigns and product launches, internal tool creation for business processes and workflow automation, educational projects demonstrating modern web patterns and best practices, and client presentations showing interactive demos instead of static mockups. Portfolio builders generate professional showcases with custom layouts and animations. Dashboard creators produce data visualization interfaces with charts graphs and metrics. Blog platforms establish content management systems with posts categories and search. Chat applications implement real-time communication with message threading. E-commerce solutions build shopping experiences with product catalogs carts and checkout flows.
