ChatGPT can write a complete website in a single answer, but the answer is a block of code in a chat. Paste that code in the box above and press Publish this page: you get a real address to send people, with HTTPS, and you don't need an account to try it.
How it works
- Ask for one file. "Make a one-page website for my bakery as a single HTML file, with the CSS and JavaScript inside it."
- Copy the code with the copy button on ChatGPT's code block (or from the canvas), and paste it in the box above.
- Publish it. The page is live in seconds at a
*.lobsite.appaddress for 6 hours; Keep it free → keeps it for good in a free account.
Prompts that publish cleanly
ChatGPT's first draft often splits the page into several files or links to files that don't exist. A few words in the prompt avoid that:
- "As a single HTML file" keeps the CSS and JavaScript inside the page, so there's one thing to paste.
- "No build step, no npm": a React or Vite project needs building before it's a website. If ChatGPT already gave you one, build it (
npm run build) and drop thedistfolder in the Drop files tab instead. - "Load libraries from a CDN by full https URL": Tailwind, Chart.js or Alpine work when they're loaded that way.
- "Use placeholder images from full URLs", or put your own images next to the HTML in a folder and drop the folder.

Let ChatGPT publish it: a custom connector
ChatGPT can call Lobsite itself through a custom connector, a remote MCP server. In ChatGPT's settings, with developer mode on, create a connector with this URL:
https://lobsite.com/api/mcp
Then, in a chat with the connector enabled, ask "Publish this page with Lobsite". ChatGPT sends the page through the deploy_files tool and answers with the address and the claim link. Which ChatGPT plans can add custom connectors is up to OpenAI; copying and pasting works on every plan, including free. More on the MCP page.
A deploy without an account is live for 6 hours. The claim link keeps it, free.
Every site gets a *.lobsite.app address with HTTPS from the first deploy.
Point a form at /_lobsite/forms/contact. Spam filtering included.
npx lobsite mcp for coding agents, lobsite.com/api/mcp for chat assistants.
Preview before going live. Roll back in one click, redirects and all.
A paid plan feature: add one DNS record and the site moves to your domain. Every site has HTTPS on any plan.
Sharing the chat, or publishing a site
| Share the ChatGPT chat | Publish on Lobsite | |
|---|---|---|
| What people see | The conversation, with the code in it | The website itself |
| Works on a phone like a site | No | Yes |
| Your own images and pages | No | Yes: drop a folder |
| A contact form that emails you | No | Yes, once the site is in an account |
| Custom domain | No | Paid plan, coming soon |
| Account needed | Your ChatGPT account | No for 6 hours; free to keep |
Frequently asked questions
Is it free to host a ChatGPT website?
Yes. Publishing without an account is free for 6 hours, and a free account keeps one site for good with 10 GB of bandwidth a month.
ChatGPT gave me several files. What do I do?
Save them in one folder with the same names ChatGPT used (index.html, style.css, script.js), then drop the folder in the Drop files tab. Or ask ChatGPT to merge them into a single HTML file and paste that.
The page is blank after publishing. Why?
Usually it's React or TypeScript code that needs a build first, or a script loaded from a file that wasn't included. Ask ChatGPT for a single self-contained HTML file, or build the project and drop the dist folder.
Can I change the page later?
Yes. Paste the new version in this browser and press Update: the same address shows it. After you keep the site, deploy changes from the dashboard or with npx lobsite.
Is the page private?
No: anyone with the address can open it, so don't publish anything you wouldn't share. Temporary sites aren't indexed by search engines.
