Quickstart
From zero to your first preview URL in about sixty seconds. No CLI, no git, no config files.
Sign in
Open mythos.new and sign in with Google, GitHub, or email. Every new account starts with 5 free credits — enough to scaffold one project and run one edit pass, which is exactly what this quickstart uses.
Create a project
On the workspace home, click "New project". Pick a scaffold — Vite + React 18 for landing pages, Next.js 15 for content-heavy sites and apps with routes. You can not switch a project between scaffolds later; create a new one instead.
Send your first prompt
The prompt box is the single entry point. Be specific — the agent reads your prompt as a brief, not a search query:
// Good — concrete, visual, mentions sections Build a landing page for "Velvet Salt Spa", a float-tank spa in Oslo. Warm dark palette. Hero with a booking CTA, 3-step process, price list, testimonial row, FAQ, contact form. // Too vague — you get a generic template make me a spa website
Hit ⌘ enter to send. The agent scaffolds the project, saves the first source snapshot, and opens the sandbox preview. Files stream into the file tree as the agent writes them.
What to read next
That is the happy path. If you want the longer walkthrough with screenshots and common gotchas, jump to "Your first project". If you want to understand how to write prompts that hit on the first try, read "Writing prompts".
