Stack Diagnostic — Most Founders Fail This Test

    Is Your Lovable Project Still on the Old Stack?

    Lovable silently upgraded new projects to TanStack Start with SSR. Old projects stayed on Vite. Most founders do not know which stack they are on — and every day they wait, their competitors outrank them.

    Check Your Stack in 30 Seconds

    No tools. No signup. Just your Lovable project and 30 seconds.

    How to check:

    1. 1.Export your Lovable project to GitHub (or download the ZIP).
    2. 2.Look at the root directory.
    3. 3.If you see app.config.ts or app.config.js — you are on the new TanStack stack.
    4. 4.If you see vite.config.ts or main.tsx — you are on the old Vite stack.

    Does this sound like your project?

    Your Lovable project was started before April 20, 2026Critical
    View Page Source shows a blank <div id="root"> or loading spinnerCritical
    Your site does not appear in Google search resultsCritical
    Multipage navigation feels sluggish or broken

    If you checked even one box, your project is on the old stack.

    What the Old Stack Costs You

    Google Cannot See Your Site.

    And neither can your customers.

    Zero Google Indexing

    Googlebot sees a blank <div id="root">. Your content is invisible. Your competitors rank. You do not.

    No Social Previews

    Share your link on LinkedIn or Twitter. No image. No title. No description. Just a raw URL that looks broken.

    Broken Multipage

    Deep links to /pricing or /about return 404 on refresh. No SSR means no real routing. Your site is a single-page illusion.

    Old Stack vs. New Stack

    Two Realities. One Platform.

    Migration Roadmap

    If liftable: exact steps, timeline, and cost. If not: honest assessment so you do not waste money on a dead end.

    Go / No-Go Decision

    You get a clear yes or no: is migration worth it? If yes, implementation is $1,499 flat. If no, you saved yourself a costly mistake.

    How I know this: I discovered the stack change in April 2026 by experimenting with Lovable's export pipeline. No changelog. No announcement. Just a silent upgrade that left old projects behind.

    FAQ

    Everything you need to know about migrating from Lovable to Next.js

    Did Lovable announce this?

    Not loudly. No changelog headline. No email blast. I found it by accident because I test my clients' builds like a paranoid person.

    Will my old project auto-update?

    No. Lovable does not migrate existing projects to the new stack. You're frozen in time unless you act.

    Is TanStack Start better than Next.js?

    For Lovable-native projects? It's the right call. For founders who want to own their infrastructure and never worry about another platform pivot? Next.js is still the permanent exit. I do both migrations.

    Do I still need Lovable Cloud?

    If you're on the new stack, server-side data loaders handle most of what Lovable Cloud was hacking around. But if you're on the old stack, Cloud is still your only lifeline.

    The new stack is live. The old stack is deprecated. The gap between them is where projects die.
