An index.html is a web page, but it isn’t a website yet - it only exists on your computer, so nobody else can visit it. To make it a website, it needs to be hosted on a server with an address people can type and an SSL certificate browsers trust. The shortest path: zip the folder, upload it to a platform like Yetty, and it’s live on its own address in minutes - free, and exactly as you designed it.
If an AI built this file for you (Claude, ChatGPT, Cursor - doesn’t matter), you’re in the most common situation on the internet right now. The design is done. The last step is the one nobody explains. Let’s do it gently.
Why double-clicking it isn’t enough
When you open index.html on your computer, the browser reads it straight off your disk. It looks perfect - to you, on this machine. But the address bar says something like file:///Users/you/..., and that address only works on your computer. A website is the same file living on a computer that’s always on, always connected, and reachable by a real address. That’s all “hosting” means.
What your index.html is missing
Four small things separate “a file that opens” from “a website that works”:
- An address. Something people can type - first a free one, later your own domain.
- SSL. The padlock. Without it, browsers show scary warnings and Google ranks you lower. You shouldn’t have to know how certificates work - a good host does this automatically.
- A way to edit it. You will spot a typo the day after launch. Fixing it shouldn’t mean reopening your AI tool and re-uploading everything.
- A working contact form. Your AI probably drew a lovely form - but a static HTML form has nowhere to send its messages. Someone has to catch them.
The shortest honest path
You don’t need to learn servers, and you don’t need to rebuild anything. The whole flow is:
- Zip the folder that contains index.html (keep it at the top, with its images and CSS beside it).
- Upload the zip to Yetty. The conversion is free, and it doesn’t touch your design - your site goes live byte-for-byte as you built it, no page builder, no “close enough” rebuild.
- It’s live in minutes on a free yetty.site address, SSL already on. Your form starts working too - messages land in a leads inbox instead of vanishing.
When you’re ready for your own address, a wizard walks you through it - here’s how connecting a custom domain works, step by step.
Then you can edit it in plain language
Once live, the text, images and links of your page become editable cards - change a word and the design doesn’t break. Every change is saved as a version, so nothing you do is ever unrecoverable. And if you built the site with an AI, that same AI can keep managing the live site for you. It stays your site, just finally out in the world.

FAQ
Can I just open index.html in my browser and share the link?
No - a file:// link points to your own disk, so it only works on your computer. To share it, the file has to be hosted on a server with a public address.
Do I need to know how to code to put my index.html online?
No. If you can zip a folder and upload it, you can go live. Hosting, SSL and the address are handled for you, and afterwards you edit in plain language, not code.
Is it free to make my index.html a live website?
On Yetty, yes - conversion is free and your site goes live free on a yetty.site address. You only move to the Live plan when you want things like your own custom domain.
