Convert JSON to Zod, generate mock APIs, and build Tailwind v4 gradients in seconds. No servers. No tracking. Your data never leaves the browser.
Built specifically for:
{
"user": {
"id": 1,
"name": "Alice",
"email": "[email protected]",
"isActive": true
}
}const userSchema = z.object({
user: z.object({
id: z.number(),
name: z.string(),
email: z.string().email(),
isActive: z.boolean()
})
