You made screens in Vercel v0 that people already like. The canvas looks right. Friends can click through. Now you want those screens in a home you control — your code, your place to run it, your passwords and keys. This page is that move: so the v0 canvas is no longer the only place the product can live.
Leaving v0 means this: you hold the component tree in a repo you own, you run it on a Next (or similar) host that is not the v0 canvas, you move passwords and data with a plan, and you prove screens and URLs still work before you tell everyone the new address. You are done when the app starts without opening v0 to regenerate a page.
Where v0 moves get stuck
Pasting components is not a safe cutover
Screens leave the canvas easily. Auth callbacks, env that only worked in preview, and public paths v0 exposed do not — unless you plan them.
Thinking “same screens” means same accounts
People signed in on a preview host. That sign-in needs its own plan. Pretty components are not the same as someone opening the new site and getting in.
Changing your site address too early
Get the owned Next app working first. Secrets that lived in a shareable v0 preview must not sit in the public bundle. Certificates, sign-in links, and email move together.
“We can always regenerate” with no real plan
A real way back means a frozen component checklist and a practiced reverse — not hope that the next prompt looks the same.
Only testing the happy canvas click-through
Also try an old account, a brand-new signup, empty states, uploads, and every public path v0 exposed for search.
The calm v0 order
Inventory v0 routes and components, practice the move, then switch
We do not change your site address just to look fast. We change it after path parity passes and a practiced way back exists.
01
Freeze a visual checklist of critical v0 screens
Prefer shared primitives over page-level pastes so tokens move once.
02
Map v0 preview auth and env to production hosts
Sessions issued on preview hosts will not magically work on production.
03
Stage redirects for every public path v0 exposed
Canonicals and Open Graph must never keep citing a throwaway preview URL.
04
Sign a short “screens and accounts still work” note, then limit reverse
Name sample accounts, permissions, media, SEO paths, and who can put the last preview back in charge.
How to
How to leave v0 without guessing
Move v0 components, secrets, and public URLs. Success is a parity note plus a practiced way back.
Step 01
Inventory v0 routes, components, env, auth, and media
List generated vs hand-tuned React. Capture fonts and assets that lived only in preview.
Step 02
Sync into an owned repo and make it build in CI
Diff dependency locks — v0 sessions drift fast.
Step 03
Remount secrets and OAuth to production hosts
Plan forced re-auth or token exchange; tell operators before you flip.
Step 04
Prove path parity on a staging alias
Same journeys as the canvas, plus empty and failure states.
Step 05
Change DNS only after the parity note is signed
Keep a short overlap where old preview links redirect rather than 404.

“What impressed us most about CodeCross was their ability to deeply understand our vision and translate it into a complete digital solution. Unlike many agencies that just focus on technical delivery, CodeCross approached our project like true partners.”
Take the screens and flows people already like — components, design tokens, route map, and how the app starts. Leave canvas junk: unused prompt drafts, one-off regenerations, and preview-only glue. Save data (or how to reach it) on its own so nothing invents that shape later.
How do you make “it works in the v0 canvas” work elsewhere?
Write down what the canvas and preview had ready for you. Lock that list in an owned Next (or similar) app. Replace “it worked because v0 regenerated it” with a real start note and CI build. The check should fail if the only way to fix a screen is to open v0 again.
How should passwords and data move off v0 preview?
Copy secret names from the preview into a template. Make fresh values on production — never leave keys in a shareable v0 preview. Remount user identifiers to your production sign-in. Update return links before you change the site address. Rotate anything that ever lived in preview.
Why does “just paste the components” break on a normal Next host?
Client and server boundaries that looked fine in the generator fail under real SSR. Env leaks into the browser. Auth callbacks still expect preview hosts. Fonts and metadata lived only in the canvas. Fix structure, secrets, and paths first — green in v0 does not mean portable.
Keep the screens. Move them into a home you own.
Bring your v0 route list, how people sign in, and a few test accounts. We put your site address last — and we name the preview path you can roll back to.
