Most "cost to build a website with AI" posts give you a per-site guess. Here's a truer number, because it's the one I actually pay: every website I own runs on one flat bill of about $230 a month. Most of that, $200, is the AI that does the building. Another $20 is hosting, about $12 is a cloud build server my old machine needs, and the rest is domains. It builds as many real websites as I can make. Not $230 per site. $230 for all of them.
The AI bill doesn't scale with the number of sites. Build one or build ten, it's the same monthly number. Each new site's real added cost is basically a domain.
The whole bill, itemized (2026)
Everything I use to build and run real websites. Prices current as of 2026. Always worth a quick check, tools move.
| Piece | What it does | Cost |
|---|---|---|
| Claude (Max plan) | The AI that does the building | $200/month, flat. Builds as many sites as I can make. (You do NOT need this to build one site, see below.) |
| Cloud build server (optional) | Builds + renders when my own machine won't | ~$12/month. My setup only; a normal computer builds fine without it (see below) |
| Vercel | Hosting, live on the internet | $20/month, Vercel Pro. Required once a site is commercial; the free Hobby tier is for personal sites. One plan covers all my sites, and it stays $20 at my traffic. |
| Domain (Porkbun) | your-site.com | ~$11/year, per site |
| Stripe | Takes payments, if the site sells | $0/month; ~2.9% + 30¢ per sale, only when money actually moves |
| Brevo | Email list + automated emails | Free up to a few hundred contacts |
| Cal.com | Booking/appointments, if needed | Free tier, including taking a deposit at booking |
Read that again: the AI is the biggest monthly line, and it's flat. My own rig adds a ~$12/month cloud server, but that's a workaround for my machine (more below), and you probably won't need it. Hosting is one $20/month Vercel Pro plan that covers every site I own (the free Hobby tier isn't allowed for commercial sites, so a business pays for Pro). It's a base fee that stays $20 at my traffic. Domains are ~$11 a year each. Payment processing only costs you a cut when you make a sale. So the marginal cost of my next website is a domain.
You do NOT need the $200 plan to build a website
I'm on Claude's top tier because I build all day, every day, as a business. If you're building one site, the free tier or the ~$20/month tier is plenty, and you can cancel it the month you're done. The $200 is a professional-volume number, not the price of admission.
What that flat bill actually produces
Two real, live sites you can click right now, both on that same stack:
- someguyandai.com: the explorable 3D room, where the objects are clickable links. (3D on the web is genuinely finicky. More on what broke below.) Runs on Vercel Pro, $20/month, because it's a business and Vercel requires a paid plan for that.
- korvani.co: a full brand site with a real store selling digital products + email capture. It used to live on WordPress and paid hosting (~$130+/year in per-site fees). Rebuilt with AI onto Vercel, it now shares that one $20/month Pro plan with every other site I own: the separate per-site WordPress bill, gone, for a faster, better-looking site. No hosting bill of its own, it rides that shared $20 plan, plus Stripe's cut on actual sales.
What breaks (the honest part)
It's not "click one button." Real things that broke, and how I got through them:
- My Mac wouldn't build the sites locally. The build tool kept getting killed. Fix: a cheap cloud server (~$12/month) does the building and deploys from there. It's the one extra line on my bill, and it exists because of my machine, not because building with AI requires it.
- The standard deploy tool failed silently on this machine, so my deploy script talks to the host's API directly instead.
- AI faces get uncanny in motion. For animated or illustrated pieces, some tools warp the face. You learn which tools to use where.
None of it's a dealbreaker. But knowing how to steer through the breakage is the actual skill, and it's the thing you're really paying for when you pay someone to build it for you.
The honest takeaway
The expensive parts of a website, builder rent and the agency invoice, the AI route just deletes. Hosting shrinks to one flat $20/month plan for every site I own (or $0 if your site is personal, not a business). What's left is one flat AI bill (and you don't even need my tier for one site), that $20 of hosting, and a domain. What you pay a builder for isn't the software. It's the time, the taste, and knowing what to tell the AI so real things come out the other side. (More: what it costs to build a site with AI and no-code vs building with AI.)
FAQ
What does it really cost to build websites with AI?
The AI is the biggest monthly cost, and it's flat. Mine is $200/month on the top tier because I build constantly, but a free or ~$20/month tier builds a single site fine. Beyond that: hosting (free for a personal site, or $20/month on Vercel Pro once it's a business), a ~$11/year domain per site, and payment processing only when you make a sale.
Does it cost more to build more sites?
Barely. The AI bill is flat no matter how many sites you build, and one $20/month Vercel Pro plan covers all of them. Each additional site's real added cost is basically its domain (~$11/year).
Can AI build a real store, not just a simple page?
Yes. korvani.co sells digital products with real checkout and email capture, all on that shared $20/month Vercel Pro plan plus Stripe's per-sale fee. The same stack handles physical-product shops and booking too.
What breaks when you build a website with AI?
Real things. Local build tools choking on some machines (fix: build on a cloud server), deploy tools misbehaving, AI warping faces in motion. It's not one-click. Steering through the breakage is the actual skill.
