Custom domains, SSL, and the boring stuff every AI builder skips

Why most AI website tools punt on hosting — and what you actually need to wire up before you point paid traffic at your AI-generated site. DNS, SSL, redirects, the lot.

Most reviews of AI website builders judge them on the wrong thing. They focus on the hero output — the typography, the spacing, the wow-moment of a polished site appearing from a one-line prompt. That's the easy 10%. The hard 90% — and the part most AI tools quietly skip — is hosting.

If you can't connect a custom domain, provision SSL, set up canonical redirects (apex → www or vice versa), handle 404s, and survive a paid-ads spike, you don't have a website yet. You have a screenshot. This post is the boring infrastructure walkthrough that should ship in every AI-builder evaluation.

What "hosting" actually means

Hosting an AI-generated site involves at least seven distinct pieces:

  • DNS — pointing your domain at the right IP / hostname
  • Apex + www handling — making sure example.com and www.example.com both resolve correctly
  • SSL certificate — issuing and renewing the cert that powers HTTPS
  • CDN — serving static assets close to the visitor
  • Canonical redirects — picking apex-or-www as the One True URL
  • 404 + error pages — every site has them; AI builders often forget
  • Analytics + tracking pixel injection — for paid traffic measurement

Most AI website builders ship 1–3 of these. The minority that ship all 7 are the only ones you can actually publish on without spending a Saturday afternoon wiring infrastructure.

How most AI builders handle (or punt on) hosting

v0 (Vercel)

Hosting is on Vercel — a separate flow. You generate components in v0, copy them into a Next.js project, deploy to Vercel, then add the domain through Vercel's dashboard. SSL is automatic. The whole flow takes 30–90 minutes for someone who hasn't done it before.

Lovable

Hosting is partially integrated — Lovable can publish to a *.lovable.app subdomain. Custom domains route through their own DNS UI. SSL is handled. Multi-page is fine. Apex-vs-www edge cases are sometimes rough.

Bolt.new

Hosting is not part of the product. Bolt generates the codebase, you deploy yourself to Vercel/Netlify/your own server. SSL, domain, redirects all your problem.

Website Killer

Hosting is part of the product. Every project gets a free *.websitekiller.com subdomain on publish. Custom domains are on paid tiers — point your nameservers at our DNS or add A/CNAME records, and SSL provisions automatically via Let's Encrypt within minutes. Apex + www both resolve, canonical redirect picks one, 404s are handled by the framework.

What you need to set up if hosting isn't built in

If your AI builder of choice doesn't ship hosting (most don't), here's the minimum infrastructure list before you can run paid traffic:

  1. Buy or transfer the domain (Cloudflare Registrar, Namecheap, Porkbun)
  2. Pick a host — Vercel and Netlify are the standard options for Next.js / static sites
  3. Add the custom domain in your host's dashboard
  4. Add the DNS records (A or CNAME) the host gives you
  5. Wait for DNS propagation (typically 1–60 minutes)
  6. Verify SSL provisions — most hosts handle this automatically via Let's Encrypt
  7. Pick canonical: redirect apex → www or www → apex (one of them, not both)
  8. Set up a 404 page that doesn't break your nav
  9. Add analytics (GA4 / PostHog / Plausible)
  10. Test from a clean browser session

On a good day this takes an hour. On a bad day — when your DNS provider doesn't propagate, or your registrar is flaky, or your host's SSL provisioning queues — it takes a Saturday.

Why the hosting flow matters more than the design output

Anyone evaluating AI website builders should ship a real test: prompt to live URL on a custom domain. That's the only test that matters, because it's the only test that reflects what users actually need to do. The design output is a 30-second wow moment; the deploy flow is the rest of your week.

An AI website builder that generates a beautiful site but doesn't ship hosting isn't an AI website builder — it's an AI design tool. Both are useful. Be clear about which one you're buying.

Bonus: the SEO infrastructure that should ship by default

Beyond hosting, the SEO infrastructure list any AI-generated site needs before it can rank:

  • robots.txt configured to allow indexing (you'd be surprised how often it's blocked by default)
  • sitemap.xml that reflects every page
  • Open Graph + Twitter Card metadata for social shares
  • Schema markup (Organization, WebSite, FAQPage where applicable)
  • Canonical tags pointing at the right URL
  • Mobile-responsive markup
  • Core Web Vitals tuning — LCP under 2.5s, CLS under 0.1

Website Killer ships all 7 by default. Other AI builders ship 0–4 — read each one's docs before you trust them.

Frequently asked questions

Does Website Killer handle SSL automatically?

Yes — every published project gets SSL automatically. Free-tier subdomains are HTTPS by default. Custom domains on paid plans get SSL via Let's Encrypt within minutes of DNS propagation, with auto-renewal every 90 days.

Can I host an AI-generated site on my own server?

Yes — every Website Killer project supports source-code export, and you can deploy that exported code to Vercel, Netlify, your own VPS, or anywhere else that runs Next.js. The trade-off is that you're now managing the hosting layer yourself.

What's the difference between a free subdomain and a custom domain?

Free subdomains (yoursite.websitekiller.com) are great for sharing drafts and validating ideas. A custom domain (yourbrand.com) measurably outperforms on click-through, brand trust, branded SERP, and is required for serious paid-traffic campaigns or email-deliverability work.

How long does DNS propagation take?

Typically 1–60 minutes for most DNS providers. Some legacy registrars take up to 24 hours. Cloudflare Registrar and Porkbun usually propagate in under 5 minutes.
