Each file in a stage gets its own AI, all working at once. Stages run in order, so pages are built from finished sections.
  • Fast modelsEveryday building runs on models chosen for speed. Frontier models are one click away when a job needs them.
  • Side-by-side buildersStarjay plans the work, then gives each page and section its own AI. They run at the same time instead of one after another.
  • Built-in visionThe AI looks at screenshots of its own draft and fixes what’s off in the same pass, so you don’t wait for a second round.
  • Foundation firstYour colors, fonts, navigation, and footer are set before any page is written. Pages come out consistent, with no cleanup pass.

Build effortlessly

Paste your current site URL or a design reference. Starjay takes it from there.

  • No brief neededThe AI works from the site you share, not from your description of it. No mood boards, no explaining fonts in words.
  • The hard parts are includedAsk for it and the AI sets up forms that email you, CMS collections, search titles, and redirects. No photos? It generates images to match.
  • Watch it buildPages change on the canvas as the AI works. It’s your real, running site, not a screenshot of one.
  • Nothing to set upNo servers, no GitHub, no hosting account. Your site runs the moment you open it.

Build precisely

Results that match what you asked for, down to the pixel.

  • It sees its workThe AI compares screenshots of its draft, on desktop and mobile, with what you asked for, and fixes the differences.
  • It reads the sourceFrom a reference site, Starjay captures the real colors, fonts, sizes, and spacing, not just a picture of the page.
  • Frontier reasoningClaude Sonnet 5.5 and GPT-6.1 Sol take on the most detailed requests.
  • Your knowledge, connectedWork through Claude Code, Codex, or another MCP tool, and the AI can use your documents and files too.
  • The last pixel is yoursSelect any element and set exact values by hand.

Build on brand

Bring your brand in once. Every page stays on it.

  • Picked up from your siteGive Starjay your current site and your colors, fonts, and look come with it.
  • Defined once, used everywhereColors, fonts, and text styles live in one place. The AI builds from them, and the editor offers only them.
  • Off-brand colors get caughtIf a new color slips in, it shows up as a named brand color you can keep or replace, not buried in the code.
  • Written brand rulesAdd your voice and do’s and don’ts to the brand guide. The AI reads it on every request.
  • Shared pieces stay sharedYour navigation, footer, and repeated sections are built once, so they can’t drift from page to page.

Build safely

Approve every change. Undo anything.

  • Every change is a versionEach AI request and each round of your own edits is saved as a version. Step back to compare, or continue from any earlier one.
  • Nothing is final until you approve itKeep the session when you’re happy. Reject it, and your site, content included, goes back exactly as it was.
  • Mistakes get caught earlyThe AI checks its own work as it goes, and changes that span several files either complete or roll back. No half-finished edits.
  • Nothing lost by accidentBackups run before every AI session and around every publish. The AI never deletes your content, and images in use can’t be removed.

  • Code models already knowStarjay sites are plain Astro and Tailwind, code AI models have seen countless times. That’s why an everyday model like Luna does excellent work.
  • No proprietary formatThere’s no custom page format for the AI to learn, so it needs less instruction and makes fewer mistakes to pay for.
  • Small edits stay smallFollow-up requests change only the files involved, and the conversation’s context is reused instead of re-sent.
