An AI website agency that runs while you sleep.On autopilot 24/7, finding, building, and pitching tailored websites to businesses that don’t have one, at scale.

Klaudius runs on top of an AI agent — software that can read instructions in natural language and do real work on your computer, like writing code, running tools, building websites, or sending emails. You can run Klaudius on either Claude Code (Anthropic) or Codex (OpenAI). Both work, and the setup wizard walks you through picking one. From then on, you direct the agent in natural language. No coding required.

A Claude Code subscription (the Max plan is strongly recommended) or a ChatGPT subscription (the Pro plan is strongly recommended) for optimal site quality and throughput. All other tools Klaudius uses — CRM, hosting, data-gathering services — provide generous free tiers, more than enough for your usage with Klaudius.

Yes — Claude Pro and ChatGPT Plus both work. But I strongly recommend the higher tier on whichever path you pick (Claude Max or ChatGPT Pro), which enables the most powerful model. The websites Klaudius builds are noticeably better quality at that tier — the kind shown on this page. The higher tier pays for itself with your first sale anyway.

macOS, Linux, or Windows. Node.js 22.15 or newer and Python 3.10 or newer — but you don't set these up by hand: a single setup command, run inside Claude Code or Codex, installs whatever you're missing. You'll also want around 1.5 GB of free disk for Playwright's bundled browsers. The init wizard installs everything else: Node packages, Python packages, Playwright browsers, and the deployment CLI for whichever host you pick (Vercel, Cloudflare, Netlify, or your own server). On Windows everything runs natively in PowerShell, including the optional high-volume parallel mode — no Git Bash or WSL2 required (though WSL2 works fine if you prefer it).

It isn't tied to anything. You can run Klaudius from any Claude Code or Codex account, and switch between them whenever you like — the whole project lives on your own machine, not behind a login of ours.

It finds businesses that don't have a website — or whose website is outdated — in your chosen region, then ranks them with a proprietary scoring algorithm so the strongest opportunities — the ones most likely to buy — surface first. Everything it finds goes into a CRM that ships with the project, so it never picks the same business twice, and you can adjust any of this by just asking your agent.

There's no hard cap on the Klaudius side — the only ceiling is your AI plan's usage limits, since each site is a genuine bespoke build. As a rough guide, the highest-tier plans of Claude Code or ChatGPT Pro can comfortably build and pitch in the region of 200 a week.

Your own email account, over standard SMTP — Gmail, Outlook, Fastmail, whatever you use. It sends each pitch from your real address (saved to your Sent folder like any normal email) and reads replies from the same inbox, so the whole conversation lives in your own mailbox. Because every pitch is personal and carries a real, finished website the owner can click straight into, it lands very differently from bulk cold email — and since it goes out from your own inbox at a pace you set, your sending reputation stays in your hands. A built-in check confirms your email is authenticating correctly, and tells you exactly what to change if it isn't.

You can — everything is customisable, so you can tell your agent to stop once it's found the businesses. But leading with a finished website is what lifts the reply and conversion rates so far above ordinary cold outreach, and the build costs almost nothing since it runs inside your existing AI subscription, so I'd recommend keeping it in.

Everything happens in writing. You confirm interest, handle any small changes the customer wants on the website (logo, photos, a credential to remove), agree the price, send your bank details, register a domain on their behalf, and point the website at it. The whole conversation is usually a handful of messages over a few days, with around an hour of actual operator time per closed deal.

Yes — and Klaudius does the launch work most small-business websites never get. While you're still pitching, preview sites stay deliberately lean. The moment a client says yes, one command applies the full go-live SEO pass: proper domain setup, structured data that tells Google exactly what the business is, an FAQ written the way people ask AI assistants like ChatGPT, a sitemap, and direct submission to the search engines that accept it. New domains still take Google a little time to index — that's true of every website — but the site goes live with the fundamentals done properly, which is more than most competitors' sites can say.

Yes, if you want to offer it. Klaudius can add a built-in editor to any site it builds: a simple, password-protected admin page where the owner updates their own text, photos and reviews from their phone or computer, with changes going live in seconds. There's no WordPress, no plugins, and no monthly platform fee. It's an optional step you run after a build, and it's a common reason owners say yes — plenty of people won't commit to a website they can't update themselves.

15–20 minutes. The init wizard walks you through a seamless setup: it provisions your CRM, wires up the data-gathering APIs, connects hosting and outreach, and verifies every credential as it goes. Once it's done, you're ready to point Klaudius at a region and let it start finding, building, and pitching websites for you.

No. Klaudius is operated through your AI agent: it reads the skills, picks the right tooling, and edits the template. You direct; it builds. You don't need prior experience with Claude Code or Codex either — using Klaudius is one of the fastest ways to actually learn the agent you choose. And if you've never opened a terminal, there's a walkthrough that shows you exactly how to get started.

Klaudius can run unattended once started. Finding the businesses, gathering their info, building the websites, publishing them, and sending the personalised pitches can all happen without your supervision. Your time only goes into the conversations that begin when a business owner replies yes.

It varies, and I won't sell you a number. From day one, Klaudius can be finding businesses, building real websites, and sending personalised pitches at volume. How fast that becomes a paying client depends on how much outreach you do and how owners respond — some reply within days, others take a few weeks of steady sending. The operators who do best treat Klaudius as a pipeline they run consistently, not a one-week lottery. The 7-day money-back guarantee is there to judge whether Klaudius is right for you, not as a window to land a guaranteed sale.

I run Klaudius myself daily for UK businesses — the same product you'd install. Stretching across foreign timezones, currencies, and outreach voices I don't know firsthand isn't where I want to spend my time. I'd rather put Klaudius in your hands so you can run it wherever you choose. And the market is enormous — for example, around 9.8 million US small businesses, 1.7 million UK businesses, and 1.5 million Australian small businesses still operate without a website. Far more than any one person, or all of us put together, could ever serve.

Any populated country. You choose your operating country and language in the setup wizard, and from then on Klaudius works natively in that market. It searches the way locals search, pulls each business's real details and reviews straight from local sources, and writes every site and every pitch from scratch the way someone from there would: local phrasing, the right tone for business in that country, local currency and phone formatting. Each site reads like it was made by someone down the road from the owner. Point it at Italy and you get genuinely Italian sites, pitched to Italian owners in Italian; point it at Spain, the same in Spanish.

In practice, no. The market is enormous — around 9.8 million US small businesses alone still don't have a website, and the picture is similar in every other country (e.g. 32% in the UK, 59% in Australia). Even hundreds of you running Klaudius flat-out wouldn't make a meaningful dent. And Klaudius gives you total control over where you point it — your country, city, niche, or industry.

The site sits at an unlisted URL only you and the business owner have. The outreach links them to it; they decide whether to keep it. If they say no, the site comes down. The work is on speculation, the way an estate agent makes a brochure for a house before the seller signs. The owner is never on the hook for anything until they say yes.

Yes. Klaudius builds fast, modern websites on the same technology major companies use (Next.js), served over HTTPS from enterprise-grade hosting providers. There's no customer data or logins stored on the sites, so there's nothing sensitive to expose.
