Installed it and nothing happens?Adding the plugin doesn't switch on its connection to Ullbek, and until that's on Claude has nothing to build with. In Claude, open Customize → Plugins → Ullbek — AI website builder → Connectors and press Connect next to ullbek · Not added, then Continue, Add, and Connect once more. Four presses, no sign-in — that's step 3 below. In Claude Code, see the Claude Code steps.
The assistant that already knows your business
If you've been using Claude to think through your business — the name, what you offer, who it's for, the tone, the prices, the plan for the year — it already holds the most important ingredient of your website: the context. Every website builder makes you type all of that in again. With Ullbek connected, you don't.
You stay in the chat you already use. Ullbek supplies the workshop underneath: sites, live previews, publishing, contact forms, hosting, and your own domain. Claude does the building, drawing on everything you've told it. The result is a real, custom website built around your business — not a template with your logo dropped in.
Same account, two doorsOnce you've signed in, everything Claude builds is in your normal Ullbek account. Open app.ullbek.com anytime and continue in the Ullbek builder — same sites, same files, no import step. Switch back and forth as much as you like.
Add Ullbek to Claude
Ullbek is a plugin in Claude's directory. You add it and switch its connection on once. It takes about a minute, and you don't need an Ullbek account to start: Claude builds your first draft without one, and you sign in when you want the site live. There is nothing to pay Ullbek for — adding and connecting are free, and your Claude plan powers the conversation.

Find Ullbek in Claude
In Claude, open Customize → Plugins → Discover and search for Ullbek — or go straight to Ullbek — AI website builder. Claude may also suggest Ullbek by itself when you ask it for a website.
-
Add it
On the Ullbek page, press Add. The plugin is now installed — but its connection to Ullbek isn't on yet, so there is one more step.
-
Switch the connection on: four presses, no sign-in
Still on the Ullbek page, open its Connectors tab. It lists ullbek · Not added: press Connect beside it. (If Claude shows a Finish setup button instead, that's the same step.) Claude opens its Add custom connector form with Ullbek's name and address already filled in: press Continue. On the next step, Authentication, No sign-in is already chosen: leave it and press Add. The row now reads Not connected: press Connect once more, and it's on. You can come back to this any time under Customize → Plugins → Ullbek — AI website builder.
-
Ask for a website
Back in Claude, say what you'd like built. Claude builds a private draft and gives you a link to see it — no Ullbek account needed yet. If Claude still says Ullbek isn't connected, start a fresh chat: Ullbek joins a conversation when it begins.
-
Sign in when you want it live
When you ask Claude to publish, it shows a card in the chat asking to connect your Ullbek account. Press its button and a sign-in window opens on ullbek.com. Continue with Google or sign in with email — or create your free account right there if you're new. Review what the connection can do, allow it, then tell Claude you're done. Your draft moves into your account and goes live. You only do this once. (A draft nobody connects is kept for seven days.)
Why does Claude say “No sign-in”?A draft website needs no account, so the connection opens without one. Anything on your account — publishing, the sites you already have, anything paid — asks you to sign in to Ullbek first. Claude also shows its usual note about only connecting to developers you trust; it shows that for every connector added this way.
Claude Code
If you've already added Ullbek in Claude on the web or in the desktop app, it shows up in your Claude Code sessions too. To add it from Claude Code itself, run:
/plugin install ullbek --marketplace ullbek/ullbek-claude-plugin
Then ask for a website: Claude builds a draft without an account. To connect your Ullbek account — when you want the site live, or to reach sites you already have — run /mcp, choose plugin:ullbek:ullbek, and pick Authenticate. Your browser opens Ullbek's sign-in page — sign in or create a free account, allow the connection, and come back. Or just ask Claude to “connect Ullbek” and it walks you through it.
The plugin adds three commands: /ullbek:website builds or improves a site from what you tell Claude, /ullbek:deploy-folder puts a finished site folder from your project online, and /ullbek:connect checks the connection.
Prefer to add the connection by hand?The plugin is the simplest way in, and the only one you need. If you'd rather add Ullbek as a custom connector, this link opens Claude's connector dialog with the name and the address https://api.ullbek.com/mcp/claude filled in; press Continue, then Add, then Connect, and sign in when you publish, as above. Custom connectors are available on Claude's paid plans. In Claude Code the equivalent is claude mcp add --transport http ullbek https://api.ullbek.com/mcp/claude, then /mcp, ullbek, Authenticate.
Build your first site
Describe what you want. The more you've already discussed with Claude, the less you need to say now — just point it at what it knows.
The first time Claude uses a tool that changes something — writing a page, publishing — it asks your permission. Read-only steps like listing your sites or checking a link run without asking. Choose Always allow for the tools you're comfortable with and the build flows without interruption.
Claude then works for a few minutes: it creates the site, writes the pages, places your photos and logo, checks its own work, and hands you two links — a private preview of the real site, and, when you say the word, the live address.
From there it's a conversation. "Make the header warmer." "Add a section with the opening hours." "Use the photo I uploaded for the hero." Every change shows up in the preview; publish again whenever you're happy. Every site gets a free yourname.ullbek.site address with hosting and HTTPS included.
Getting the most out of it
Put the business in a Project
If your business plan, brand notes and offer already live in a Claude Project, start the build from inside it. Claude carries the Project's knowledge into every page, so the site reflects the real business — its offer, its voice, its customers — instead of a generic first draft.
Give it your photos
Tell Claude where your logo and photos are on the web and it brings them onto the site. Pictures that are only on your computer or phone go in through the Ullbek builder: upload them at app.ullbek.com and Claude can use them straight away. (A photo dropped into the Claude chat can't travel across the connection.) Your own pictures make a site look like yours.
Ask for a preview before publishing
The preview link is the real site, served exactly as it will go live. Open it on your phone and your laptop, click through every page, and send changes back in plain words. Publish only when it looks right.
Ask for a screenshot
"Show me a screenshot of the homepage on a phone" gets you a picture right in the chat — handy for a quick look without opening a link.
Continue in the Ullbek builder when you want the full workshop
Side-by-side live preview, the brand kit, your assets, form submissions, models to choose from: all of it is waiting at app.ullbek.com, on the same site Claude just made. Many people start a site in Claude and polish it in the builder.
What Claude can do with Ullbek
Once connected, Claude can take a site the whole way, from the first page to a live address — the full journey, not a demo:
Create & edit sites
Start a new site or keep improving an existing one — pages, sections, images, colors, the lot.
Live preview links
Ask for a preview and you get a private link to the real, running site — click it and see exactly what will go live.
Publish & go live
Free address included, secure HTTPS and all. Say the word and your site is on the internet.
Your own domain
On premium hosting, connect a domain you own — Claude walks you through the setup, record by record — or ask Claude to find you a new one, which it connects for you.
Read your messages
"Any new messages from my contact form?" — form submissions arrive in your inbox and Claude can read them back to you.
Your photos & screenshots
Your own photos and logo, placed well and sized right, plus fresh screenshots of your site right in the conversation.
Premium hosting and your own domain
The free address is yours for as long as you like. When you want the site on your own domain, ask Claude. It tells you the monthly price of premium hosting, then hands you a link to a secure checkout page, which you open and complete in your own browser. Once the site is on premium hosting, Claude takes over the technical part: it tells you exactly which DNS records to add and keeps checking until your domain answers.
No domain yet? Ask Claude to find one. It checks which names are free to register (.com, .net and .org) and what each costs per year; you pick one and pay for it the same way. A domain is its own yearly plan, separate from hosting. Once it's registered, Claude connects it to your site for you — there are no DNS records for you to add.
Nothing is charged without your yesClaude never sees or asks for your card details. Anything paid — premium hosting, a domain, extra credits — happens on a secure checkout page that you open in your browser, with the price shown before you confirm. If you've saved a way to pay in your Ullbek account, Claude names the price and that way to pay, and it is charged only after you say yes.
ChatGPT and other assistants
Ullbek works with any assistant that supports connectors — the open standard is called MCP (Model Context Protocol). ChatGPT has its own one-click install: see Use Ullbek inside ChatGPT. For Cursor, VS Code, Antigravity, Codex and other AI apps, see Use Ullbek with any AI app. In short, this is everything the assistant needs:
If your tool asks for a connection type, pick Streamable HTTP (Ullbek is a remote server, not a program on your computer). Name it anything you like, paste the URL, and skip every token and header field: the sign-in happens in your browser when you first use it.
Good to know
Is this safe?
The connection can build and publish websites on your account — and that's it. It cannot spend your money without you (a payment completes in a checkout you open yourself or, if you've saved a way to pay, only after Claude has named the price and you've said yes), Claude asks before it changes anything unless you've told it not to, and sites published from a chat pass the same content review as sites published from the builder. Sensible per-account rate limits apply.
How do I disconnect?
In Claude, open Customize → Plugins and choose Ullbek — AI website builder. The switch at the top of its page turns the plugin off without removing it; to take it out altogether, open the ··· menu and choose Remove. (If you added Ullbek as a custom connector instead, remove it under Customize → Connectors.) You can add it back anytime with the same steps. Your sites stay safe in your Ullbek account either way.
Which is better — Claude or the Ullbek builder?
They're the same account, so it's never either/or. The Ullbek builder gives you the full workshop: side-by-side live preview, brand kit, assets, models to choose from. Claude gives you convenience and context — the assistant that already knows your business can act on it. Many people start a site in a conversation and polish it in the builder.
Your website is one message away
Add Ullbek in Claude, switch it on, say what you want, and the business you've been talking about becomes a real website.
