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.
https://outer.now/mcpHow 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:
successwith the URL,failedwith the log tail, orblockedwith the exact lines to fix.
What you can build
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 (
docstool) and relays anyuser_messagefrom 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.
