title: FAQ and troubleshooting
description: Short answers to the questions every new Outer user asks — and what to do when a deploy fails.

## Building

**What can I build?**

Anything the Ilha + Void template expresses, backed by D1, KV, Durable
Objects, R2, queues, cron and realtime. Starters with copy-paste prompts:
[What you can build](/what-you-can-build).

**How long does a change take?**

Seconds to about a minute: build → review → deploy, then the URL serves the
new version. The tool call that made the change waits and reports back —
your agent doesn't need to poll.

**My app is slow to answer the first request.**

The fleet sleeps after ~30 minutes without requests and wakes on the next
one — that first request pays the cold start. It adopts the newest deploy
when it wakes.

**The page shows a "paused / building / held" screen instead of my app.**

Those are proxy-owned pages, not your code: the app has no successful
deploy yet, is paused over quota, or is held/suspended by moderation. Ask
your agent for the deploy status; [Moderation](/moderation) explains holds.

## Sign-in and accounts

**Which clients sign in with OAuth?**

Claude, Codex, ChatGPT, Gemini and Perplexity. Anything else uses the
emailed-code fallback: [Sign in](/sign-in).

**Do I need an invite code?**

During the closed beta, allowlisted emails get in directly; everyone else
pastes an `OUTER-XXXX-XXXX` code at sign-in or lands on the waitlist. One
code admits one account. Your own codes live on the console's Invites page.

**How do I revoke a client or a key?**

Console → Connections & keys, or `revoke_connection` / `revoke_api_key`
over MCP.

## Plans and limits

**Free vs Pro?**

1 app and 50 code changes a day vs 10 apps and 500 — full table:
[Plans](/plans). Billing isn't live yet, so every account is on Free during
the beta.

**What happens at 100% of a quota?**

Change/build/app/collaborator limits refuse with `quota_exceeded` plus a
`user_message` your agent relays verbatim. Requests, storage or outbound
traffic at 100% on Free pause the app until the month resets — data is kept.

## Deploys

**The deploy failed. What now?**

Paste the log tail back to your agent and ask for the fix. Build errors
name the file and line; `commit` returns `failed` with the log. Never edit
around the gate — fix the cause and commit again.

**The deploy is blocked. What now?**

`blocked` means the pre-live review flagged page text: `commit` returns the
file, the line, and an excerpt. Fix those lines and commit again — a blocked
deploy keeps the previous version serving and counts as a code change. What
trips it: [Moderation](/moderation).

**How do I undo?**

`rollback` to any earlier successful SHA (Console → Deploys → Roll back). Never counts
as a change, never a moderation target.

**Where are the logs?**

Running app: Console → Logs, or `app_logs`. Build: expand the deploy, or
`deploy_log`. Crashes grouped: Console → Errors, or `app_errors`.

## Data and domains

**Can my app send email?**

Only through an HTTP email API like Resend with your own key — never SMTP
(ports blocked) and never Void's native sender ([Email](/guides/email)).

**Can I use my own domain?**

Yes, one hostname per app on Pro, via Cloudflare for SaaS:
[Custom domains](/guides/custom-domains).

**Can I export my code?**

Pro, via `export_code` — an archive, good for 24 hours. There is no git
push; agents change code with `commit`.

## Getting help

Ask your agent first — it reads these docs over MCP. If a tool refuses
something, its `user_message` is the answer; have the agent relay it word
for word instead of working around it. During the closed beta there is no
self-serve moderation appeal: relay the message and fix the flagged lines.
