1. **Creates a new Git repository on your GitHub/ GitLab account**: Cloudflare will automatically clone and create a new repository on your account, so you can continue developing.
2. **Automatically provisions resources the app needs**: If your repository requires Cloudflare primitives like a [Workers KV namespace](/kv/), a [D1 database](/d1/), or an [R2 bucket](/r2/), Cloudflare will automatically provision them on your account and bind them to your Worker upon deployment.
3. **Configures Workers Builds (CI/CD)**: Every new push to your production branch on your newly created repository will automatically build and deploy courtesy of [Workers Builds](/workers/ci-cd/builds/).
4. **Adds preview URLs to each pull request**: If you'd like to test your changes before deploying, you can push changes to a [non-production branch](/workers/ci-cd/builds/build-branches/#configure-non-production-branch-builds) and [preview URLs](/workers/configuration/previews/) will be generated and [posted back to GitHub as a comment](/workers/ci-cd/builds/git-integration/github-integration/#pull-request-comment).

We've updated [preview URLs](/workers/configuration/previews/) for Cloudflare Workers to support long branch names.
We've updated [preview URLs](/workers/previews/) for Cloudflare Workers to support long branch names.

Previously, branch and Worker names exceeding the 63-character DNS limit would cause alias generation to fail, leaving pull requests without aliased preview URLs. This particularly impacted teams relying on descriptive branch naming.

**How to Re-enable Your Preview URL**

Alternatively, you can use Wrangler by adding the `preview_urls = true` setting to your Wrangler file and redeploying the Worker.
