Deploy an app to Deno Deploy from a local directory with the deno deploy CLI

Documented steps

1. Auth: Interactive browser login on first `deno deploy` run; the CLI stores a token in the system keyring and reuses it (deno deploy logout clears it).
2. Create an account/organization at https://console.deno.com/ - the current Deno Deploy platform. Do NOT use the deprecated Deploy Classic dashboard (dash.deno.com) or deployctl; both were discontinued July 20, 2026.
3. In your project directory run `deno deploy` to deploy interactively, or `deno deploy --app my-app-name` to target a specific app.
4. To create the app non-interactively: deno deploy create --org my-org --app my-api --source local --framework-preset fresh --build-timeout 5 --build-memory-limit 1024 --region us.
5. Add --prod to deploy straight to the production timeline (e.g. deno deploy --org my-company --app my-api --prod); otherwise the deploy lands on a development/preview timeline.
6. The CLI tarballs the directory, uploads it, and Deploy builds and serves it, returning a live URL.
7. Use deno deploy switch --org <name> --app <name> to set the default org/app context for future commands in that directory.
