Think it.Build it instantly.
A high-end, sandboxed environment that transforms plain text into production-ready React applications with zero friction.
The workflow, perfected.
Intelligence embedded at every step. From intent to deployment in seconds.
Engineering Excellence
Real engineering under the hood. Not just another wrapper.
Multi-Model Fallback
Automatic model switching with exponential backoff. If one model rate-limits, Zync seamlessly tries the next — zero failed generations.
Type-Safe Stack
TypeScript + tRPC end-to-end. Every API call is statically checked — no runtime surprises.
Sandboxed Execution
Every app runs in an isolated E2B container with its own Vite dev server. Secure and scalable.
Engineered for Speed
0.6s FCP, near-zero CLS. Code-split bundles and optimized package imports keep everything snappy.
Smart Context
System prompts ensure generated code uses only available packages and follows React best practices.
Infinite Memory
Context-aware generation using your conversation history. Iterate and refine effortlessly.
