## TL;DR
Vite is a frontend build tool focused on fast development startup, hot module replacement, and optimized production builds. Its development server relies on modern browser support for native ES modules.

## Core Explanation
During development, Vite serves source modules directly and transforms files on demand. For production, it builds optimized assets with Rollup. Plugins connect Vite to frameworks and transformations used by real applications.

## Detailed Analysis
Performance claims depend on app size, plugins, dependencies, and hardware, so public content should avoid unsupported speed numbers. The durable facts are architectural: native ESM in development, HMR support, and Rollup-based production builds.
