How to use it
- Paste your HTML into the editor, open an
.htmlfile, or start from the sample. - The preview on the right updates as you type. Switch between desktop, tablet and phone widths to check the layout.
- Press Publish it online to get a live
*.lobsite.applink. Press it again after more edits and the same link updates.
The preview runs the page for real: inline scripts, styles, and scripts and fonts from CDNs all work, the same as they will once it's online.
Put a page from ChatGPT or Claude online
AI assistants are good at writing a whole page in one go, but the result is a block of code in a chat. Paste it here to check it renders, then publish it to get a link you can send anyone. Nothing to install, no account, and no files to save.
If the assistant can run commands, it can publish for you: see Lobsite for AI agents.
How long the link lasts
A page published without an account is a temporary site: it stays up for 6 hours. To keep it, use Keep it free → after publishing and sign in or create a free account; the site moves to your account with the same address, and no longer expires. See the limits for what each plan includes.
Frequently asked questions
Is the HTML Viewer free?
Yes. Previewing and publishing are free, and you don't need an account. Published pages are temporary until you keep them with a free account.
Does my HTML get uploaded when I preview it?
No. The preview runs in your browser. Your HTML is only sent to Lobsite when you press Publish it online.
Can the page use JavaScript, CSS and images?
Yes. Inline <script> and <style> tags work, and so do scripts, stylesheets, fonts and images loaded from other sites by their full URL. To publish images or several pages of your own, deploy the folder with npx lobsite or drop it on the dashboard.
How do I update a page I published?
Edit it here and press Update in the same browser: the same link shows the new version. Once you've kept the site in your account, deploy changes from the dashboard or with npx lobsite.
Can I use my own domain?
Custom domains come with the paid plan, which is coming soon. Until then, pages live on a *.lobsite.app address with HTTPS.
