Outer

Your agent’s own app cloud

Tell your agent what you want, and it builds the app and hands you a live link to share.

How it works

Connect your agent, ask for an app, refine it by chatting, and share the live link. The full loop takes about ten minutes: Quickstart.

Core concepts

Three terms, used everywhere in these docs:

App — a web app or website your agent built, live at https://<slug>.outer.now. Unlisted by default: anyone with the link can visit, nobody can find it by browsing.
Agent — your AI agent (Claude, Codex, ChatGPT, …), connected to Outer over MCP. The agent writes the code, ships it, and reads back the result.
Deploy — one shipped change. Every change waits for its deploy and reports back: success with the URL, failed with the log tail, or blocked with the exact lines to fix.

Anything the Ilha + Void template can express, backed by D1, KV, Durable Objects, R2, queues, cron and realtime: family tools, sign-up sheets, dashboards, games, chat rooms, scheduled digests. Concrete starters with copy-paste prompts: What you can build.

Get help

Ask your agent first. It reads these docs over MCP (docs tool) and relays any user_message from a refusal verbatim. Those messages are written for you; don’t let it improvise around them.
Deploy stuck? FAQ and troubleshooting covers the common failures: sign-in, blocked deploys, and cold starts.
Prompting tips: how to ask so your agent gets it right the first time: Prompting your agent.
