Quickstart

Connect your chat app, ask for an app, see it live — the Outer loop in about ten minutes.

Get a live app in about ten minutes. The example below builds a family grocery list. Swap in your own idea. The steps are the same.

Connect your agent

One line per client (full table in Connect your agent):

  • Claude Code: claude mcp add --transport http outer https://outer.now/mcp, then /mcp → outer to sign in
  • claude.ai, Desktop, mobile: Settings → Connectors → Add custom connector → https://outer.now/mcp
  • Codex CLI, IDE, ChatGPT desktop app: codex mcp add outer --url https://outer.now/mcp, then codex mcp login outer
  • Anything else: OAuth if supported, else the emailed-code fallback in Sign in

Ask for the app

Paste a scoped first prompt. One screen, no login, no database yet:

Build a grocery list app for my family on Outer. One page: an input to add items, a list with checkboxes, a filter for bought vs. still needed. No login, no sharing yet — just the list. Read the Outer quickstart and Ilha guides first, then create the app and show me the live link.

  1. Tell your agent the slug you want to use.
  2. Your agent calls create_app with that slug.
  3. Open the live link it returns: https://<your-slug>.outer.now.

Taken slugs are rejected, and deleted names stay reserved for 30 days. A live Ilha + Void app serves in seconds. Unlisted by default: not indexed, reachable by link. Building a landing page, portfolio, or blog instead? Say so in the prompt. The agent passes template: "website" for the content-site starter. See Templates.

Make one change

Add a “who bought it” label: tapping a bought item lets you type a name.

  1. Send the change in one short message.
  2. Your agent makes the change and deploys it.
  3. Read the deploy result it reports: success with the URL, failed with the log tail, or blocked with the lines to fix.

Code is formatted before the change lands. If a deploy fails, your agent names the file and line from the log tail. Paste that back and ask for a fix.

Share it

  1. Ask your agent to share the app.
  2. It returns the URL, share text, and a QR code for the family chat.
  3. Open the Console to watch the deploy, the logs, and who visits. How sharing works: Sharing your app.

Rules that bite newcomers

  • Ask for the building blocks by name. Your agent reads the Ilha and Void guides before writing code, and it reads Agents → Quickstart for the full loop.
  • No strong profanity in page text, seed data, or the app name. The deploy is blocked and the previous version keeps serving. See Moderation.
  • After each change, ask your agent what it checked. To undo, ask for a rollback, which never counts as a change. To delete, confirm with your slug typed again. The name stays reserved for 30 days.
  • Free gives 1 app and 50 code changes a day (Limits). When your agent reports a refusal, its message is written for you. Ask it to relay that message word for word.
