Wrangler allows you to view the 100 most recent versions and deployments. Refer to the [`versions list`](/workers/wrangler/commands/workers/#versions-list) and [`deployments list`](/workers/wrangler/commands/workers/#deployments-list) documentation for the commands.

The Deployments tab shows the deployment history and IDs. It does not display the code of previous deployments.

### Retrieve code from a previous deployment

The Cloudflare dashboard and Wrangler do not provide a built-in way to download the code of a previous deployment. You can retrieve a specific deployment's code using the Cloudflare API:
```bash
curl -s -H "Authorization: Bearer <API_TOKEN>" \
"https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/workers/scripts/<WORKER_NAME>/content/v2?deployment=<DEPLOYMENT_ID>"
```
You can find the <DEPLOYMENT_ID> in the Deployments tab in the dashboard, or by running wrangler deployments list. The API token requires Workers Scripts: Read permission.
