01Built-in: Publish in the app
The Preview tab has a 🚀 Publish button. One click uploads the current version to vibesafebuilder.com/p/<id> — no account, no setup, no file renaming. It's security-scanned server-side before it goes live, and it's installable to a phone's home screen with offline support built in (see the user guide). Republish any time to update the same link.
Use everything below only if you want a custom domain (myapp.com instead of a vibesafebuilder.com link), or want the file hosted somewhere you fully control.
02Before you deploy elsewhere: one prep step
Every host below expects a file named index.html as the entry point. Your download is named my-app.html — rename it to index.html before uploading anywhere. That's the only preparation needed: there's no build command, no npm install, no framework to configure. It's one file with inline <style> and <script> — every static host on this list treats that as a complete, deployable site.
03Netlify Drop
Best for: the fastest possible way to get a real URL with zero account setup.
Go to app.netlify.com/drop
No sign-up required to get a live link; create a free account only if you want to keep it long-term or add a custom domain.
Drag your renamed index.html onto the page
Netlify uploads it and gives you a live https://random-name.netlify.app URL immediately.
Optional: claim it and add a domain
Create an account to keep the site permanently, rename the subdomain, or connect your own domain under Site settings → Domain management.
04Vercel
Best for: builders who want a dashboard, previews, and easy custom-domain HTTPS.
Create a free account at vercel.com
Sign up with GitHub, GitLab, or email.
New Project → Deploy without Git
Vercel supports dragging in a folder containing your renamed index.html — no repository required for a single static file.
Add your domain
Project → Settings → Domains. Point your domain's DNS at Vercel and HTTPS is issued automatically.
05Cloudflare Pages
Best for: the fastest global CDN and generous free tier, if you already use Cloudflare for DNS.
Create a free Cloudflare account
Go to the Pages section of the dashboard.
Create a project → Upload assets
Upload your renamed index.html directly — no Git repo needed for a direct upload deploy.
Attach your domain
Custom domains → Set up a domain. Works especially smoothly if the domain's DNS is already on Cloudflare.
06GitHub Pages
Best for: if you already have a GitHub account and want your app's source visible/version-controlled publicly.
Create a new repository
Upload your renamed index.html to it (GitHub's web UI lets you drag-and-drop a file, no Git CLI required).
Enable Pages
Repository → Settings → Pages → set the source branch to main and folder to /root.
Visit your live URL
Live in a minute or two at yourusername.github.io/repo-name. Custom domains are supported under the same Pages settings.
07Surge.sh
Best for: builders comfortable with a terminal who want the fastest possible command-line deploy.
Install Surge
npm install -g surge (requires Node.js installed).
Deploy from your app's folder
With your renamed index.html in an otherwise-empty folder, run surge and follow the prompts — first run asks you to create a free account.
Get your URL
Surge picks a random *.surge.sh domain by default, or you can type your own subdomain — and your own custom domain via surge --domain yourdomain.com.
08Firebase Hosting
Best for: if you're already in the Firebase/Google Cloud ecosystem, or want to add a real backend to your app later.
Install the Firebase CLI
npm install -g firebase-tools, then firebase login.
Initialize hosting
firebase init hosting in a folder containing your renamed index.html as the public directory.
Deploy
firebase deploy — live instantly at yourproject.web.app, with custom domain support in the Hosting dashboard.
09Which one should I use?
| Platform | Setup | Account needed? | Custom domain | Best for |
|---|---|---|---|---|
| Our Publish button | One click | No | No | Instant sharing, zero setup |
| Netlify Drop | Drag & drop | Only to keep it | ✓ | Fastest external option |
| Vercel | Drag folder or CLI | Yes | ✓ | Dashboard + previews |
| Cloudflare Pages | Upload assets | Yes | ✓ | Fastest global CDN |
| GitHub Pages | Upload to repo | Yes | ✓ | Public, version-controlled |
| Surge.sh | CLI command | Yes | ✓ | Terminal users, scripting |
| Firebase Hosting | CLI init + deploy | Yes | ✓ | Adding a backend later |
10Adding a custom domain
The general pattern is the same everywhere: buy a domain from any registrar (Namecheap, Cloudflare Registrar, Google Domains successors, etc.), then in your chosen host's dashboard add the domain and point its DNS records (usually a CNAME or A record) at the values the host gives you. All six platforms above issue free HTTPS certificates automatically once the domain is verified — no extra cost or manual certificate setup.
11A note on installability elsewhere
Your downloaded file already includes a manifest and icon, so it's installable to a phone's home screen wherever you host it. What it won't have outside our own domain is offline caching — that part of our Launch Check / publish pipeline registers a service worker scoped to vibesafebuilder.com/p/<id> specifically, since offline caching requires the host to serve that worker file itself. If you self-host and want offline support too, you'd add your own small service-worker script to the platform you choose — outside the scope of this guide, but every platform above supports it the same way any static site does.
