Zod vs Typia vs AJV — I Built a Vite Plugin That Makes Zod 60x Faster With Zero Code Changes

When I first released Zod AOT, it required wrapping every schema with compile(): import { compile } from "zod-aot"; const UserSchema = compile( z.object({ name: z.string().min(1), email: z.email(), }) ); The #1 feedback was: "I don't want to change my code." Fair. So I removed that requirement. Zod AOT now has an autoDiscover mode — a Vite plugin that finds your Zod schemas at build time, compiles them into optimized validators, and replaces them in-place. Your schema files stay pure Zod. No imports from zod-aot. No wrappers. Just this: // vite.config.ts import zodAot from "zod-aot/vite"; export default defineConfig({ plugins: [zodAot({ autoDiscover: true })], }); That's it. Every exported Zod schema in your project gets AOT-compiled at build time. I also added Typia and AJV to the benchmarks, built a two-phase "Fast Path" validator, and shipped a diagnostic CLI. Here's what changed. autoDiscover: How It Works The challenge is detecting Zod schemas without any marker in the source code
