You can now open secure, interactive shell sessions to running Sandboxes with the Vercel Sandbox CLI.

pnpm i -g sandbox
sandbox login
sandbox create # If you don't have a running Sandbox to SSH into
sandbox ssh <sandbox-id>

Note: While you’re connected, the Sandbox timeout is automatically extended in 5-minute increments to help avoid unexpected disconnections, for up to 5 hours.

Learn more in the Sandbox CLI docs.
