Create a tunnel and save its key

You need to belong to a workspace. Open its Tunnels page. If you belong to more than one workspace, switch to the right one first.

1. 1On Tunnels, choose Create tunnel.
2. 2Enter a Name, for example aspire-quickstart. Wait for Name available: names are unique across the whole Groundhog service, not just your workspace.
3. 3Check the Address preview. This is the HTTPS address you will open once your computer is connected.
4. 4Choose Create tunnel.

The command the dashboard shows uses --port 3000 as an example. Enter the port your app listens on instead: for http://localhost:5173, use --port 5173.

Using Aspire? You don’t need a port. Aspire finds the app’s endpoint itself.

After you create the tunnel, Groundhog shows its Connection key. The key lets a client connect this tunnel. It is not your sign-in password.

1. 1Choose Copy key and save the key in your password manager, or paste it straight into Aspire while the page is open.
2. 2Note the tunnel’s name and Tunnel address.
3. 3Select I saved my connection key, then choose Done.

Open the tunnel and choose More actions → Rotate key. The new key replaces the old one at once, so update every client that used it. See Rotate or revoke a key.

A new tunnel waits for your computer. Creating it does not start forwarding. Continue with one of these:

• Your first tunnel with Aspire
• Connect an app with the CLI
