title: CLI
description: Built-in CLI for managing your project.
---
Better Auth comes with a built-in CLI to help you manage the database schemas, initialize your project, generate a secret key for your application, and gather diagnostic information about your setup.
## Generate
The `generate` command creates the schema required by Better Auth. If you're using a database adapter like Prisma or Drizzle, this command will generate the right schema for your ORM. If you're using the built-in Kysely adapter, it will generate an SQL file you can run directly on your database.
```bash title="Terminal"
npx @better-auth/cli@latest generate
```
### Options
- `--output` - Where to save the generated schema. For Prisma, it will be saved in prisma/schema.prisma. For Drizzle, it goes to schema.ts in your project root. For Kysely, it's an SQL file saved as schema.sql in your project root.
- `--config` - The path to your Better Auth config file. By default, the CLI will search for a auth.ts file in **./**, **./utils**, **./lib**, or any of these directories under `src` directory.
- `--yes` - Skip the confirmation prompt and generate the schema directly.
## Migrate
The migrate command applies the Better Auth schema directly to your database. This is available if you're using the built-in Kysely adapter. For other adapters, you'll need to apply the schema using your ORM's migration tool.
```bash title="Terminal"
npx @better-auth/cli@latest migrate
```
### Options
- `--config` - The path to your Better Auth config file. By default, the CLI will search for a auth.ts file in **./**, **./utils**, **./lib**, or any of these directories under `src` directory.
- `--yes` - Skip the confirmation prompt and apply the schema directly.
## Init
The `init` command allows you to initialize Better Auth in your project.
```bash title="Terminal"
npx @better-auth/cli@latest init
```
### Options
- `--name` - The name of your application. (Defaults to your `package.json`'s `name` property.)
- `--framework` - The framework your codebase is using. Currently, the only supported framework is `nextjs`.
- `--plugins` - The plugins you want to use. You can specify multiple plugins by separating them with a comma.
- `--database` - The database you want to use. Currently, the only supported database is `sqlite`.
- `--package-manager` - The package manager you want to use. Currently, the only supported package managers are `npm`, `pnpm`, `yarn`, `bun`. (Defaults to the manager you used to initialize the CLI.)
## Info
The `info` command provides diagnostic information about your Better Auth setup and environment. Useful for debugging and sharing when seeking support.
```bash title="Terminal"
npx @better-auth/cli@latest info
```
### Output
The command displays:
- **System**: OS, CPU, memory, Node.js version
- **Package Manager**: Detected manager and version
- **Better Auth**: Version and configuration (sensitive data auto-redacted)
- **Frameworks**: Detected frameworks (Next.js, React, Vue, etc.)
- **Databases**: Database clients and ORMs (Prisma, Drizzle, etc.)
### Options
- `--config` - Path to your Better Auth config file
- `--json` - Output as JSON for sharing or programmatic use
### Examples
```bash
# Basic usage
npx @better-auth/cli@latest info
# Custom config path
npx @better-auth/cli@latest info --config ./config/auth.ts
# JSON output
npx @better-auth/cli@latest info --json > auth-info.json
```
Sensitive data like secrets, API keys, and database URLs are automatically replaced with `[REDACTED]` for safe sharing.
## Secret
The CLI also provides a way to generate a secret key for your Better Auth instance.
```bash title="Terminal"
npx @better-auth/cli@latest secret
```
## Common Issues
**Error: Cannot find module X**
If you see this error, it means the CLI can't resolve imported modules in your Better Auth config file. We're working on a fix for many of these issues, but in the meantime, you can try the following:
- Remove any import aliases in your config file and use relative paths instead. After running the CLI, you can revert to using aliases.
