Quick answer
To connect a v0 website to an existing domain: publish the page first, then attach the domain you already own. Path A — stay in Vercel: v0 Publish → Production, then Domains in the Vercel project. Path B — leave Vercel: open the Code tab, paste into GeminiLaunch, Go Live (free HTTPS subdomain), then connect yourbrand.com from Lite ($5/mo) with one DNS record. Full registrar steps: launch an AI site on a custom URL.
Existing domain
Two paths to put yourbrand.com on a v0 site
Owning a domain is not enough — DNS must point at wherever the site is hosted. Pick the path that matches where you want to host.
Path A · Stay on Vercel
v0 Publish → Vercel Domains
Use Publish → Publish to Production in v0, then add your existing domain in the Vercel project (Domains). Follow Vercel’s DNS instructions at your registrar. Fastest if you want to stay inside that ecosystem.
Path B · Leave Vercel
Code tab → GeminiLaunch → Lite DNS
Copy from the Code tab, publish on GeminiLaunch free, then attach the same domain you already own from Lite ($5/mo, 1 domain) or Pro (up to 5). One DNS record — no Vercel project required.
Key insight
“v0 hosting” is the live URL. “v0 domains” is pointing yourbrand.com at that URL. Do the host step before DNS, or the domain has nowhere to resolve.
Definition
What is v0.dev website hosting?
v0.dev website hosting means taking the React UI that v0.dev generated and publishing it on a permanent public URL — not just the in-app preview. v0 builds the page; a host like GeminiLaunch, Vercel, Netlify, or Cloudflare Pages puts it on the internet.
People also search "how to connect v0 website to existing domain" and "v0 hosting" / "v0 domains." Those mean: get a live URL, then point a domain you already own at it. v0 Publish lands on Vercel Domains; the Code-tab path lets you host on GeminiLaunch and attach DNS from Lite — or reuse the same paste workflow for ChatGPT, Claude, Gemini, bolt, and Lovable.
Be honest
Three ways to publish from v0.dev
v0.dev, built by Vercel, is one of the fastest ways to generate a working React page from a single prompt. After you like the preview, you are not stuck with one deploy path — there are three common ones.
1. v0 one-click Publish → Vercel
Click Publish → Publish to Production in v0. It builds and deploys to Vercel in about 30–60 seconds with no GitHub required. This is the fastest path if you are happy staying inside Vercel's ecosystem (account, project, domains, and plan limits).
2. GitHub → Vercel (CI/CD)
Export or connect a GitHub repo so every push deploys on Vercel. Best for teams that already live in Git — not required just to get a first live URL.
3. Code tab → GeminiLaunch (no Vercel)
Open the Code tab, copy the React component, paste into GeminiLaunch, and publish. You leave Vercel entirely: free subdomain, custom domain from Lite ($5/mo), and the same paste-and-publish flow you can reuse for every other AI tool — not only v0.
Why choose GeminiLaunch over v0 Publish?
- • Hosting outside Vercel — your site is not tied to a Vercel project or Hobby commercial limits
- • One workflow across tools — v0 today, ChatGPT / Claude / Gemini / bolt / Lovable tomorrow, same paste → publish path
- • Simple custom domains from Lite without managing Vercel DNS for every experiment
If you want the shortest path inside Vercel, use v0's Publish button. For a full platform comparison, read GeminiLaunch vs Vercel.

Step-by-step
Host your v0.dev website without Vercel — 4 steps
Use this path when you want a live URL outside Vercel. If you prefer staying on Vercel, use Publish → Publish to Production in v0 instead — no Code tab needed.
Open v0.dev and generate your website
Go to v0.dev and describe the page you want — a landing page, portfolio, pricing page, or waitlist. v0 generates a working React + Tailwind component and shows a live preview in seconds.
Tip: Be specific: "Create a landing page for a project management SaaS with a hero, feature grid, pricing table, and signup form" works better than "make me a landing page."
Copy the code from v0's Code tab
Skip Publish-to-Vercel for this workflow. Next to the preview, open the Code tab (not GitHub export). Copy the full component. If v0 split the page into multiple files, ask it to combine everything into one self-contained component first.
Tip: Ask v0: "Give me this entire page as one single React component with all the code combined." That avoids missing imports when you paste.
Paste into GeminiLaunch and publish
Create a new project on GeminiLaunch and paste the component into the editor. GeminiLaunch auto-detects React — no npm install, no build command, no config. Click Go Live and you get a public URL immediately.
Tip: Set your page title and meta description in GeminiLaunch before publishing so search and social previews show the right information.
Connect your existing domain
Your free GeminiLaunch subdomain works right away for sharing and demos. When you already own yourbrand.com, upgrade to Lite ($5/mo) for 1 domain or Pro ($15/mo) for up to 5. Add the DNS record GeminiLaunch shows at your registrar — the same domain you already bought — and your v0-built site goes live there. No Vercel account required.
Tip: Lite includes 1 custom domain; Pro supports up to 5. Most DNS changes propagate within 5 to 30 minutes. Full walkthrough: launch an AI site on a custom URL.
Live URL
What your published v0 site looks like
After you paste and publish, GeminiLaunch gives you a permanent HTTPS URL on a free subdomain — for example a free GeminiLaunch subdomain. Anyone can open it without a Vercel or GitHub account. When you already own a branded domain, connect yourbrand.com from Lite with one DNS record.
Same workflow for similar tools
Built in bolt.new or Lovable instead? The paste-and-publish path is the same — see host bolt.new or Lovable on your own domain.
Copy-paste prompts
Best prompts for building v0.dev websites
Better prompts give you a single, clean component that is easier to copy in one piece. Paste any of these directly into v0.dev.
SaaS landing page
Create a landing page for a project management SaaS. Include a hero section, feature grid, pricing table, testimonials, and a signup form. Output this as a single self-contained React component.
Portfolio website
Create a minimal portfolio site for a freelance designer. Include a project grid, about section, and contact form. Dark theme, clean typography. Output as one combined React component, no separate files.
Agency landing page
Create a one-page website for a digital marketing agency. Include services, case studies, client logos, and a contact CTA. Combine everything into a single React component I can copy in one piece.
Avoid these
Common mistakes with v0.dev hosting
Thinking GitHub is required just to get a live URL from v0
It is not. v0's Publish button can deploy straight to Vercel with no GitHub. GitHub is optional for teams that want a repo. If you want hosting outside Vercel, use the Code tab instead.
Assuming v0's in-app preview is your permanent site
The preview inside v0 is for building. For a shareable public URL you still publish — either with v0 → Vercel, or by copying the code to another host like GeminiLaunch.
Pasting split component files without combining them first
v0 sometimes generates a page as multiple linked components. Paste only one file and the page breaks. Ask v0 for a single self-contained component before copying.
Forgetting meta tags before publishing
v0 focuses on the visible design, not SEO metadata. Fill in title and meta description in GeminiLaunch so the page looks correct in Google, Slack, and social shares.
Expecting your existing domain to work before DNS updates
Buying or owning a domain is not the same as pointing it at your v0 site. After you attach it in GeminiLaunch (or Vercel Domains), you still add the DNS record at the registrar and wait for propagation.
Honest limits
When to stay on Vercel (use v0 Publish)
GeminiLaunch is built for getting AI-generated frontends live fast outside Vercel. Prefer v0's one-click Publish (or a GitHub → Vercel workflow) when you need:
You're happy staying in the Vercel ecosystem and just want the fastest live URL from v0
You need server-side rendering, API routes, or a database connection
You're building a full multi-page Next.js app with dynamic routing
You need Vercel-specific features like edge functions or ISR
Your team requires Git-based CI/CD with staging and production branches
For those cases, stay on Vercel — either with one-click Publish or a connected repo. For landing pages, portfolios, and demos where you want hosting outside that stack (or one workflow across every AI tool), paste-and-publish on GeminiLaunch is usually the better fit.

Frequently asked questions about hosting v0.dev websites
Can I deploy a v0.dev website without using Vercel?
Yes. Copy your code from v0's Code tab, paste it into GeminiLaunch, and publish a live URL in seconds — no Vercel account needed. You can also stay on Vercel with v0's one-click Publish button if you prefer that ecosystem.
Does v0 have a one-click Publish button to Vercel without GitHub?
Yes. In v0 you can click Publish → Publish to Production and deploy straight to Vercel without creating a GitHub repo. That is the fastest path if you are happy hosting on Vercel. Choose GeminiLaunch when you want hosting outside Vercel, or one paste-and-publish workflow across ChatGPT, Claude, Gemini, bolt, and Lovable — not only v0.
Why use GeminiLaunch instead of v0's one-click Publish?
Use v0 Publish when you want the shortest path inside Vercel. Use GeminiLaunch when you want to leave Vercel's ecosystem, avoid tying the site to a Vercel project/account limits for commercial work, or keep the same hosting workflow for every AI tool you use — not just v0.
Does v0.dev host websites by itself?
No. v0 generates and previews your code. A permanent public URL comes from publishing — either via v0's Publish-to-Vercel flow, or by copying the code to another host like GeminiLaunch, Netlify, or Cloudflare Pages.
How do I get my v0 code without exporting to GitHub?
Open the Code tab next to your v0 preview and copy the component code directly. You can also use v0's Publish button to deploy to Vercel without GitHub if you want to stay on Vercel.
How do I connect a v0 website to an existing domain?
Publish the v0 code first (Code tab → GeminiLaunch, or v0 Publish → Vercel). Then attach the domain you already own: on GeminiLaunch that starts on Lite ($5/mo) with one DNS record at your registrar; on Vercel use Domains in the project settings after Publish. Deep DNS steps: /blogs/how-to-launch-ai-website-custom-url.
Can I add a custom domain to my v0.dev project without Vercel?
Yes. Publish your v0 code on GeminiLaunch, upgrade to Lite ($5/mo) for 1 domain or Pro ($15/mo) for up to 5, add one DNS record at your domain registrar, and your site goes live on your own domain. Vercel’s Publish flow also supports custom domains if you stay on Vercel.
What is v0 hosting vs v0 domains?
v0 hosting means putting the generated React on a public HTTPS URL. v0 domains means pointing yourbrand.com at that live site. v0 itself does not replace a host — Publish uses Vercel for both URL and domains, or you host elsewhere (GeminiLaunch) and connect DNS there.
Does GeminiLaunch support v0.dev's React and Tailwind code?
Yes. GeminiLaunch auto-detects React and JSX, including components generated by v0.dev with Tailwind. No build step or configuration is required.
What is the difference between v0.dev and Vercel?
v0.dev generates website code from a text prompt. Vercel is a hosting platform — made by the same company — that v0 integrates with for one-click Publish and optional GitHub deploys. They are separate products: you can build with v0 and host elsewhere.
Is it free to host a v0.dev website on GeminiLaunch?
Yes. GeminiLaunch's free plan includes up to 3 live sites on GeminiLaunch subdomains. A custom domain starts on Lite at $5/mo (1 domain); unlimited sites and up to 5 domains require the Pro plan at $15/mo.
Can I also host bolt.new or Lovable the same way?
Yes — same paste-and-publish flow. See our guide on hosting a bolt.new or Lovable website on your own domain for the tool-specific steps.
What if I already have React code from ChatGPT or Claude, not just v0?
The same workflow applies. Our deploy React without Vercel guide compares six methods for any AI-generated React output.
