Server / Client Split
Enforce variable boundaries at define-time with automatic VITE_ prefix validation. Server secrets never reach the browser.
Build-time Leak Detection
Scans client bundles for server secret values before they ship. Catches leaks that code review misses.
Runtime Access Protection
Warns or errors when `virtual:env/server` is imported from a client environment. Configurable per Vite 8 environment.
Auto Type Generation
Generates `vite-env.d.ts` on every build start. No manual type declarations that drift from reality.
Auto .env.example
Generate documented `.env.example` files from your Zod schema with types, defaults, and required flags.
Platform Presets
Pre-built schemas for Vercel, Railway, and Netlify. One import gives you validated, typed access to all platform variables.
Zod v4 + Standard Schema
First-class Zod v4 support with rich type inference. Or use Valibot, ArkType, or any Standard Schema validator.
