Quickstart

1. Open Spaceboy

There is no sign-up form. Open Spaceboy and you land in your workspace: a live preview of a working starter app on one side, your agent's chat on the other. Behind the scenes everything has already been created for you — a free organization, your first project, and a running sandbox. No account, no credit card, no setup.

Your workspace is held by this browser until you attach a sign-in (step 5) — do that before switching devices or clearing browser data.

2. Describe what you want

Tell your agent what you're building, in plain language — the audience, what it offers, the feeling it should have. Attach images if you have them: screenshots, sketches, mood boards. The agent plans the work, makes the changes, and everything lands in the live preview as it happens.

Iterate the way you'd talk to a designer sitting next to you: "make the header warmer", "add a page for the menu", "the photos should be bigger". You can also point at anything in the preview to tweak it directly or hand it to the agent.

3. Make it yours

The Design menu in the workspace top bar is the fast lane for how your app looks. Switch what you're building — a landing page, a web app, a store, or a game — and watch the preview repaint in seconds; browse complete starter projects; or adjust looks, color scheme, and layout without touching the chat.

Want something none of the templates offer? Imagine composes a brand-new design from your description — at template quality, painted straight into your live preview.

4. Publish

Click Publish in the workspace top bar and your app goes live on the web, on its own URL, ready to share. There's no target to pick and nothing to configure — Spaceboy ships the workspace you're looking at, and you can publish again any time. Publishing is where you pay: every template is Premium at $20/month, and you can ship up to a full-stack app. Everything before that is free.

5. Keep it everywhere

So far, everything lives in a guest workspace that only this browser holds. Attach a sign-in — Google, Apple, Microsoft, or an emailed code — and the same workspace opens on any device: your desktop, your laptop, the iPhone app. If you already have a Spaceboy account, signing in with it takes you back to that account instead.

6. Go further

Your project is real production software, and everything around it is ready when you are:

• Custom domain — serve your published app from a domain you own.
• Team — name your organization, invite teammates, and build side by side.
• Tasks — hand bigger pieces of work to your agents and walk away; each builds in its own isolated workspace.
• Every surface — direct your agents from the iPhone app, Slack, or the terminal.

Planning a bigger build?

When you want agents to build a complete, multi-page product in one orchestrated run — with a reviewed plan and a cost estimate before anything starts — use the step-by-step setup path instead: describe your vision, review the draft it becomes, and watch the build land in checkpoints.
