## No config? No problem. Just \`wrangler deploy\`

You can now deploy any existing project to Cloudflare Workers — even without a Wrangler configuration file — and `wrangler deploy` will *just work*.

Starting with Wrangler **4.68.0**, running [`wrangler deploy`](https://developers.cloudflare.com/workers/wrangler/commands/workers/#deploy) [automatically configures your project](https://developers.cloudflare.com/workers/framework-guides/automatic-configuration/) by detecting your framework, installing required adapters, and deploying it to Cloudflare Workers.

#### Using Wrangler locally

```sh
npx wrangler deploy
```

When you run `wrangler deploy` in a project without a configuration file, Wrangler:

1. Detects your framework from `package.json`
2. Prompts you to confirm the detected settings
3. Installs any required adapters
4. Generates a `wrangler.jsonc` [configuration file](https://developers.cloudflare.com/workers/wrangler/configuration/)
5. Deploys your project to Cloudflare Workers

You can also use [`wrangler setup`](https://developers.cloudflare.com/workers/wrangler/commands/workers/#setup) to configure your project without deploying, and `wrangler setup --yes` to apply the detected configuration without confirmation.

#### Using the Cloudflare dashboard

When you connect a repository through the [Workers dashboard ↗︎](https://dash.cloudflare.com/?to=/:account/workers-and-pages/create), a [pull request is generated](https://developers.cloudflare.com/workers/ci-cd/builds/automatic-prs/) for you with all necessary files, and a [preview deployment](https://developers.cloudflare.com/workers/versions-and-deployments/version-urls/) to check before merging.

Note

A pull request is only generated when your deploy command is `npx wrangler deploy`. If you use a custom deploy command, automatic configuration still runs but a PR is not created.

#### Background

In December 2025, we [introduced automatic configuration](https://developers.cloudflare.com/changelog/post/2025-12-16-wrangler-autoconfig/) as an experimental feature. It is now generally available and the default behavior.
