Multiple instances

An instance name is the local label that selects one site’s saved configuration. Give each instance a name that clearly identifies its purpose or hostname.

List saved instances

yarn manage instances

The output identifies production, preview, and local state and marks the current default when one exists.

Select the default

yarn manage use <instance-name>

You can also avoid changing the default by adding --instance <name> to a supported command:

yarn manage status --instance personal-notes-example-com
yarn manage deploy --instance studio-updates-example-com

Add another site

Use yarn manage init --instance <name> for a new site. Use yarn manage connect --worker <worker-name> --instance <name> for an existing compatible Worker. Initialization may create Cloudflare resources; connect is read-only in Cloudflare.

Avoid targeting mistakes

Before a deployment, restore, authentication change, or removal:

1. Run yarn manage status --instance <name>.
2. Match the Worker name and Cloudflare account to the intended site.
3. Use the same explicit --instance value for the change.

Never choose an account or instance only because it appears first in a list.
