# CLI Overview

> Create and manage backend projects from the command line

The Base44 CLI is a command-line tool for building projects with Base44's [backend service](/developers/backend/overview/introduction). Use it to create projects, define your data models as entities, and sync everything with Base44. Projects created with the CLI use Base44's backend service and aren't currently integrated with Base44's app editor.

<Note>
  The CLI and backend service are currently in beta. We're actively improving the platform and documentation based on user feedback. Share your thoughts and feature requests on our [GitHub Discussions page](https://github.com/orgs/base44/discussions).

## Installation

```bash theme={null}
npm install -g base44@latest
```

Or run [commands](/developers/references/cli/commands/introduction) directly with npx:

```bash theme={null}
npx base44@latest <command>
```

Requires Node.js 20.19.0 or higher.

## Create projects

Create new Base44 backend projects with the [`create`](/developers/references/cli/commands/create) command. You can choose from available templates to get started quickly.

See our quickstart articles for a detailed walkthrough:

* [Backend-only quickstart](/developers/backend/quickstart/templates/quickstart-backend-only)
* [React quickstart](/developers/backend/quickstart/templates/quickstart-react-template)

## Start from a Base44 app

If you've built an app with the [Base44 app editor](https://base44.com) and want to develop it locally, use the [`eject`](/developers/references/cli/commands/eject) command to create a new Base44 backend project with a local codebase. For a step-by-step guide, see [Start from an Existing Base44 App](/developers/backend/overview/start-from-existing-app).

## Link existing backend projects

If you have existing Base44 backend project code, such as from an [example app](https://github.com/base44/apps-examples), use the [`link`](/developers/references/cli/commands/link) command to connect it to a Base44 backend. For a step-by-step guide, see [Link an Existing Backend Project](/developers/backend/overview/link-existing-project).

## Manage resources

Define [entity schemas](/developers/backend/resources/entities/overview) as JSON files, write [serverless functions](/developers/backend/resources/backend-functions/overview) in TypeScript, configure [AI agents](/developers/backend/resources/agents-config), and set up [OAuth connectors](/developers/backend/resources/connectors) for external services. The CLI validates your definitions, reports what changed, and keeps your local and remote resources in sync.

## Develop locally

Start a local development server with [`dev`](/developers/references/cli/commands/dev) to test your project on your machine without deploying. See the [Local development](/developers/backend/overview/local-dev/local-development-overview) guide for details.

## Deploy your project

Deploy all your project resources to Base44 with the [`deploy`](/developers/references/cli/commands/deploy) command. This pushes entities, functions, connectors, auth config, and site files in a single operation. You can also deploy resources individually using [`entities push`](/developers/references/cli/commands/entities-push), [`functions deploy`](/developers/references/cli/commands/functions-deploy), [`connectors push`](/developers/references/cli/commands/connectors-push), [`auth push`](/developers/references/cli/commands/auth-push), and [`site deploy`](/developers/references/cli/commands/site-deploy). After deploying, use [`site open`](/developers/references/cli/commands/site-open) to open your live site in the browser.

## Configure authentication

Manage your app's login methods from the command line. Pull the current config with [`auth pull`](/developers/references/cli/commands/auth-pull), toggle email/password with [`auth password-login`](/developers/references/cli/commands/auth-password-login), toggle social providers (Google, Microsoft, Facebook, Apple) with [`auth social-login`](/developers/references/cli/commands/auth-social-login), and push your changes with [`auth push`](/developers/references/cli/commands/auth-push). Auth config is also included when you run [`deploy`](/developers/references/cli/commands/deploy).

## Run scripts

Run standalone TypeScript or JavaScript scripts that interact with your app using [`exec`](/developers/references/cli/commands/exec). A pre-authenticated SDK client is available as a global `base44` variable, so you can access entities, functions, and integrations without any setup code. Useful for data migrations, seed scripts, ad-hoc queries, and automation. See the [Standalone scripts](/developers/backend/overview/run-scripts) guide for a full walkthrough.
