- LocalStorage-backed state (no DB required for demo)

Zero-latency persistence using the browser's native key-value store for instant, serverless prototyping.

LocalStorage-backed state bypasses the overhead of a traditional database by anchoring data directly to the client's browser. It is the optimal choice for rapid demos (MVP validation) where you need to persist user sessions or UI preferences across page refreshes without writing a single line of backend code. By leveraging the 5MB synchronous storage limit, you can build fully functional CRUD applications that run entirely on the edge. This approach eliminates API latency, simplifies the deployment pipeline, and ensures your demo remains functional even in offline environments.
