Reactive State + Cloudflare D1 Sync
All components compile to pure React + Vite code with instant HMR.
How NinjaAi transforms ideas into deployed apps
A battle-tested architecture that isolates AI compute on fast VPS nodes while serving live previews and metadata from Cloudflare global edge.
Prompt & Plan
Type what you want to build in plain English. Multi-agent CrewAI analyzes your intent, architects components, and writes production-ready React + Vite code.
Instant Edge Preview
A high-speed builder compiles your app in milliseconds. The build is streamed to Cloudflare R2 and served instantly by our shared Preview Worker.
Conversational Refinement
Ask for changes naturally: 'Make the hero darker', 'Add Stripe checkout', 'Optimize for mobile'. NinjaAi generates focused code diffs in real-time.
Immutable Versioning & Rollback
Every single successful build produces an immutable snapshot backed by Git and Cloudflare D1. Roll back to any previous version instantly with zero rebuilds.
Built on Next.js 16, Cloudflare D1 + R2, and Isolated VPS AI Workers
FastAPI executes Python agents & pnpm builds in ephemeral workspaces. Cloudflare D1 guarantees zero-latency metadata queries, and R2 delivers durable project archives with zero egress fees.
Everything you need to go from idea to production
Crafted for founders, product engineers, and designers who demand speed without sacrificing code quality or flexibility.
Clean React 19 + Vite Codebase
No proprietary runtime wrappers. NinjaAi writes clean, modern TypeScript, Tailwind CSS, and React components you can read, modify, and understand.
Immutable Snapshots & Instant Rollback
Every build is stored immutably in R2. Jump between versions with a single click in D1 without ever waiting for a recompile.
CrewAI Multi-Agent Pipeline
Multiple specialized AI agents collaborate on component structure, styling tokens, accessibility, and state reactivity before compiling.
Zero Vendor Lock-In & Export
You own 100% of the code. Download your project as a standard Vite repo or push commits directly to your GitHub repository.
Global Edge Preview & Production
Deployments and previews run across Cloudflare's 300+ city edge locations with sub-50ms TTFB worldwide and zero egress charges.
Responsive & PWA Ready by Default
Every generated application includes responsive grid breakpoints, touch targets, and Web App Manifests ready for mobile installation.
