AI Studio just leveled up from “generate a pretty frontend” to build a real full-stack web app. New projects run on TanStack Start: server-rendered pages, real backend (server functions and REST APIs), and a proper secrets vault. Prompt it. Ship it. Watch search engines, social cards, and users all see the same live site.

⚡ The new stack: TanStack Start

New AI Studio projects are born full-stack. Not a static SPA pretending to be a website: a React app with a server, routes, APIs, and a published runtime.

🔍 Native SSR: finally, SEO that actually works

Every page is rendered on the server, on every request. Google, LinkedIn, Slack unfurls: they get real HTML (titles, descriptions, headings, the actual copy). No empty #root. No “enable prerender and hope.” Disable JavaScript and the page is still there. That’s not a tweak. That’s how the web is supposed to work.

🧠 Server functions: backend without the backend headache

Need to load data, talk to an API, or keep logic off the client? AI Studio can write server functions that run on the server and stay there. The browser calls them. It never sees the implementation. Your secret sauce stays secret.

🔌 REST APIs: a real HTTP backend

Need a public API? You can ship REST endpoints too (/api/...): JSON in, JSON out, GET/POST, webhooks, curl. Server functions power the app from the inside. Server routes are the HTTP API the rest of the world can call.

🔐 Secrets: keys that don’t leak into the frontend

Drop API keys and tokens into Secrets. They never land in the client bundle, never get pasted into chat, never show up in View Source. Preview and production both get them. Your app can finally call real services without you shipping credentials to every visitor.

🌐 Build full web apps. For real.

SSR + server functions + REST APIs + secrets is the combo: multi-page sites with unique URLs, server-backed data, public APIs, private integrations, and a publish path that’s a live app, not a static zip. Describe the product. AI Studio builds the stack.

♻️ What about current React projects?

They keep running the same way. Nothing changes for existing Vite/React apps. A migration guide to move them onto the new framework is coming soon.
