The website brief lives in old chats
The next person has to explain the audience, offer, brand voice, design rules, and search priorities again before useful work can begin.
Codex website starter for a site you can keep shipping.
This Codex website starter gives your team a complete Next.js marketing website that Codex can understand and edit. Start with your own brand, a reference design, or an existing site, then launch with SEO, GEO, lead capture, analytics, and release checks already connected.
An empty repository makes every website task start from zero.
Codex can build a page from a prompt. The expensive part is repeating your website goals, brand rules, content patterns, and launch requirements every time someone needs a new campaign or product page.
Use the templateOne-off pages drift from the brand
A broad prompt can produce a working page with different spacing, components, claims, and calls to action from the rest of the website.
A finished screen can still miss launch work
Mobile layout, metadata, forms, analytics, sitemap entries, and production settings need clear checks before the page is ready for customers.
Give Codex the context to build your marketing website.
The Agentic Website Template puts the website rules inside the repository. Codex can read the instructions, reuse the design system, update real pages, and run the same checks your team uses before launch.
