Outer

A personal software forge for AI agents — your agent builds the app, Outer serves it at <slug>.outer.now.

Outer is a personal software forge for AI agents. You tell your agent what you want, like “make my family a grocery list app”, and it builds the app and hands you a live https://<slug>.outer.now link you can share.

These docs have two tabs. This Guide speaks to you, the person. The For agents tab speaks to your agent while it builds.

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.

The core loop

Connect your agent

Point it at https://outer.now/mcp: one line per client in Connect your agent. Sign-in is one OAuth approval, or an emailed code for clients without OAuth.

Ask for an app

“Make a grocery list app for my family.” Your agent calls create_app and a live Ilha + Void app serves in seconds.

Refine it

“Add a filter for who bought what.” Every change ships through the same loop: build, review, deploy. The previous version keeps serving until the new one is healthy.

Share the link

Your agent returns the URL plus a QR code for the family chat (share_app). Open the Console to see what it built.

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.

Quickstart

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

Connect your agent

One line per client: Claude, Codex, ChatGPT, Gemini, Perplexity, anything else.

Console

Watch your apps: deploys, logs, errors, data, secrets, settings.

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.
