+description: Modern alternatives for TypeScript schema validation
+---
+
+# TypeScript schema validation
+
+This page contains common, recommended alternatives for TypeScript schema validation. [`valibot`](https://valibot.dev/) and [`zod/mini`](https://zod.dev/packages/mini) are modular, tree-shakable options that both support [Standard Schema](https://standardschema.dev/), allowing them to work with schema-agnostic integrations.
+
+See [Schema Benchmarks](https://schemabenchmarks.dev/download) to explore other schema validation libraries and compare their bundle sizes and runtime behavior.
+
+When migrating between schema libraries, verify optionality, empty-string handling, type coercion, unknown object keys, error messages, and synchronous versus asynchronous validation.
+
+## `valibot`
+
+Valibot uses a functional API with tree-shakable schema and validation actions.
+
+```ts
+import * as v from 'valibot'
+
+const personSchema = v.object({
+  name: v.pipe(v.string(), v.nonEmpty()),
+  age: v.pipe(v.number(), v.minValue(0))
+})
+
+const person = v.parse(personSchema, input)
+```
+
+Valibot schemas are required by default; wrap optional fields with `v.optional(...)`. Use `v.nonEmpty()` when empty strings are invalid, and compose further checks with `v.pipe(...)`. `v.parse` is synchronous; use `v.parseAsync` for asynchronous validation.
+
+Valibot makes transformations explicit (for example, `v.toNumber()`), and `v.object` removes unknown keys. Use `v.looseObject` when those keys need to be preserved.
+
+## `zod/mini`
+
+Zod Mini is the tree-shakable, functional API included with Zod 4. Install `zod@^4.0.0` and import the `zod/mini` subpath:
+
+```ts
+import * as z from 'zod/mini'
+
+const personSchema = z.object({
+  name: z.string().check(z.minLength(1)),
+  age: z.number().check(z.gte(0))
+})
+
+const person = personSchema.parse(input)
+```
+
+Zod Mini schemas are required by default; wrap optional fields with `z.optional(...)`. Its functional checks are passed to the schema with `.check(...)`, while `parse`, `safeParse`, `parseAsync`, and `safeParseAsync` remain schema methods. As with Valibot, `z.object` strips unknown keys by default; use `z.looseObject` to preserve them.
+
+Zod Mini does not load a default error-message locale. Configure one explicitly, for example with `z.config(z.locales.en())`, when callers depend on English error messages.
