Preview Deployments

Preview deployments allow you to see how your documentation changes will look before merging them into your main branch. When you open a pull request, Docs automatically creates a preview deployment and can post a comment with a link to preview your changes.

Enable in the Dashboard

Configure preview deployments and pull request comments in the Scalar Dashboard under your project settings. You can:

  • Enable preview deployments for every pull request
  • Enable automatic comments on pull requests with a direct link to the preview

GitHub Pull Request Comments for Preview Deployments

When enabled in the Dashboard, Scalar posts a comment on each pull request with a direct link to the preview deployment:

PR Comment

CLI

If your Docs project is not connected to your GitHub repository, use the CLI publish in preview mode (e.g. for pull requests) without going live:

npx @scalar/cli project publish --slug your-docs --preview
