How do I publish an HTML page my AI just built?

Short answer: connect a publishing tool to your assistant over MCP, then tell the assistant to publish the page. It uploads the HTML and hands you back a public URL. With Hoaster, that's a one-time browser sign-in, and from then on it's the sentence "publish it." You can point your own custom domain at the result, and re-publishing updates the same URL in place.

The rest of this page explains the options, and why the obvious one is usually the wrong one.

What you're actually trying to do

An AI assistant can produce a complete, self-contained HTML file — a landing page, a one-pager, an infographic, an interactive chart. What it cannot do on its own is put that file somewhere the public can reach it. That step needs a host: a machine that will serve your file at an address.

So the question is only ever "which host, and how much work is it to get the file there?"

The three common answers

1. The assistant's own share button. Fastest, and free. But the page lives on the assistant's domain and wears its branding. If you're sending it to a client, you're advertising the tool you used, on a URL that isn't yours and that you can't move.

2. GitHub Pages. Free, and it works — but it routes you through a developer's toolchain to get there. You need a repository, a commit, the file named exactly index.html, and Pages enabled on the right branch. If any of those is off you get your source code or a 404, with nothing telling you which. Fine if you already use Git. A genuinely bad afternoon if you don't.

3. A publishing tool connected to the assistant. The assistant does the upload itself, because it has a tool for it. You say "publish it"; you get a URL. No files leave your conversation by hand, and nothing about the result mentions the tool that made it.

How the third one works

Publishing tools connect to assistants over the Model Context Protocol (MCP) — an open standard for giving an assistant a capability it doesn't have natively. Once connected, the assistant simply has a publish tool, the same way it has a search tool.

With Hoaster specifically:

1. Add the connector in ChatGPT or Claude and sign in through your browser. There are no API keys to generate or paste.
2. Ask for whatever you want built.
3. Say "publish it."
4. You get back a public URL.

Say "publish it" again after a revision and the same URL updates — the link you already sent your client keeps working.

Using your own domain

A URL you don't own is a rental. If the page is client-facing, you usually want it on your domain — pricing.youragency.com rather than someone else's subdomain.

Hoaster lets you attach a custom domain to a space: you add the domain, drop in the DNS record it gives you, and published pages appear there. The certificate is issued automatically. Pages carry no Hoaster branding at all, so the work reads as yours — because it is.

When you shouldn't bother

If you already have a deploy pipeline, keep using it. If the page is throwaway and nobody but you will see it, the assistant's share button is fine.

The moment it goes to a client, or needs to keep working next month, or needs to sit on your domain — that's when the last mile stops being an afterthought.
