 ## Making Preview URLs inaccessible
 
-Preview URLs run on your [`workers.dev` subdomain](/workers/configuration/routing/workers-dev/). To make preview URLs inaccessible, you must disable your Workers `workers.dev` subdomain. Learn how to [disable your Workers `workers.dev` subdomain](/workers/configuration/routing/workers-dev/#disabling-workersdev).
+Preview URLs run on your [`workers.dev` subdomain](/workers/configuration/routing/workers-dev/). You can disable preview URLs to make them inaccessible.

+### Disable on the Cloudflare dashboard
+
+1. Log into the [Cloudflare dashboard](https://dash.cloudflare.com/) and select your account.
+2. Go to **Workers** > your Worker.
+3. Go to **Settings**.
+4. In the "Domains & Routes" section click "Disable" on "Preview URLs".
+5. Confirm you want to disable.
+
+### Disable in Wrangler
+
+::note
+Wrangler vXX or higher is required to use this feature.
+::
+
+In your `wrangler.toml` you can add `preview_urls = false` to disable preview URLs from being accessible.
+
+```toml
+name = "my-worker"
+compatibility_date = "2024-01-01"
+preview_urls = false
+```
+
+This will be applied when doing `wrangler deploy` or `wrangler triggers deploy` if using [Gradual Deployments](/workers/configuration/versions-and-deployments/gradual-deployments).
 
 ## Limitations
 
 - Preview URLs are not generated for Workers that implement a [Durable Object](/durable-objects/).
 - Preview URLs are not currently generated for [Workers for Platforms](/cloudflare-for-platforms/workers-for-platforms/) [user Workers](/cloudflare-for-platforms/workers-for-platforms/reference/how-workers-for-platforms-works/#user-workers). This is a temporary limitation, we are working to remove it.
 - You cannot currently configure Preview URLs to run on a subdomain other than [`workers.dev`](/workers/configuration/routing/workers-dev/).
+- You cannot use `wrangler tail`, [Workers Logs](/workers/observability/logs/workers-logs) or other similar tools to view logs for preview URLs.

 If you do not specify `workers_dev = false` but add a [`routes` component](/workers/wrangler/configuration/#routes) to your `wrangler.toml`, the value of `workers_dev` will be inferred as `false` on the next deploy.
