### Generate and apply Better Auth schema with CLI commands for Drizzle, Prisma, and Kysely

Source: https://layerbase.com/docs/auth

Run the Better Auth CLI to generate the schema for your adapter, then apply it with your ORM's migration tool. Drizzle writes schema.ts and uses drizzle-kit push; Prisma writes prisma/schema.prisma and uses prisma migrate; Kysely writes schema.sql and can use the built-in migrate command. The CLI is published as @better-auth/cli, also invokable as npx auth@latest.

```bash
# Drizzle: generate schema.ts, then push (or generate + run a migration)
npx @better-auth/cli@latest generate
npx drizzle-kit push

# Prisma: generate into prisma/schema.prisma, then migrate
npx @better-auth/cli@latest generate
npx prisma migrate dev

# Kysely or raw SQL: generate schema.sql, then apply it
npx @better-auth/cli@latest generate
npx @better-auth/cli@latest migrate   # built-in Kysely adapter only
```
