ChatGPT wrote your page and it works. The catch is that it lives inside a conversation: there is no "download site" button, and what you copy often gets saved wrong and stops working.
Ask for it as a single file
Before copying anything, ask for exactly this: "give me everything in one index.html file, with the CSS and JavaScript inline, no external dependencies". That is the difference between finishing in two minutes and fighting with loose files that cannot find each other.
An .html file with everything inside is already a site. The browser understands it as-is and there is nothing to build. It is the easiest case there is — and the only tool on this list that hands it to you that directly.
Save it under the exact name
This is where it breaks most often. You copy the block, paste it into your computer’s text editor, and end up with index.html.txt — the extension hidden, because Windows and macOS hide it by default. That file is not a page: it is text that looks like code.
- The name has to be
index.html, with nothing after it. - Save it as UTF-8 or your accented characters turn into
é. - Double-click it before publishing: if you see your page, it is fine; if you see code, it was saved as text.
If it is already several files
As the site grows, ChatGPT starts handing you index.html, styles.css and script.js separately. Ask it to leave them in a downloadable zip, or save each one under its exact name inside a single folder. The links between files (href="styles.css") only work if the names match what the HTML says.
Check this before you publish
If at some point you asked it to connect a service — a form, a map, a weather API — it probably wrote the key straight into the code. On a web page everything in the file is public: anyone who opens your site can read it.
Search your index.html for anything that looks like api_key, sk-, token, or a long string of letters and numbers. If you find one, rotate it and take it out of the code. FluentOps flags this on every publish — on every plan, including the free one — but it is better if it never gets there.
Publishing it
- Put your
index.htmlin a folder (a single file on its own works too). - Drag the folder into FluentOps. It detects plain HTML and does not try to build anything.
- Get your public address with its padlock, ready to share.
No commands, nothing to install, no repository. And the site does not pause or expire afterwards: the free plan holds up to 21, and none of them switch off for lack of traffic.
If your tool was not ChatGPT
Each one hands you something different — Claude gives you an artifact, Lovable and v0 give you a project that has to be built. The full comparison is in the guide to all six tools.
And if you have never published anything before, start here.
