How an HTML file saves itself
Start with a regular HTML file and add ClayJS: the file edits and saves itself in place, so your team can shape the live app directly.
- Make one with AI or pick a free template.
- One ClayJS script tag adds page editing, a visual CMS, and owner controls, each of them optional, so the file can stay lightweight.
- No build, deploy, or database: on Hyperclay, saves go live right away and sync with teammates.
- An open format, so you own the file: download your HTML anytime, or run files offline with Hyperclay Local and HTML Clay.
Give more of your ideas a chance.
AI can build a full-stack app in a day, and when a tool needs a database and a server, you should build one. Most ideas are not there yet, and you will not know which ones matter until people actually use them. An HTML file costs nothing to start and nothing to throw away, so you can try ten ideas with your team today and grow the winners into full applications later.
Use the AI agent you already pay for.
Let Claude Code, Cursor, or your own coding agent read and edit your HTML files on Hyperclay from the command line or through an MCP server.

Change the page and it's live.
Add a column or drag a row around, and every change syncs live to your team.
Each save strips out the editing tools, so visitors only see a clean, fast page.
Owner-only edit controls
Instant publish
Shape your HTML file with code, its own interface, AI, a built-in visual CMS, or offline on disk
A sidebar CMS generated from your page.
Open the CMS panel and Hyperclay builds an editing form from your file's content. Typing in a field updates the page beside it live.

One-click AI CMS setup
Download your HTML file and run it anywhere.
Double-click your downloaded file on your laptop and it opens, edits, and saves back to itself completely offline.
The interface is not a
picture of the software.
It is the software.
- Browsers turn HTML into a live tree of elements called the DOM.
- Most web apps treat the DOM as a temporary picture of state stored somewhere else.
- Self-saving HTML files treat the file itself as the truth.
How saving works
Because the page itself holds the app and its state, saving the HTML file is all it takes to publish a change.
One HTML file. Your application and its state live together in a single file.
Edit in place. You shape the live DOM directly in the browser, right on the page.
Persist clean HTML. Saving copies the live DOM, strips owner-only editing controls, and writes clean HTML as the next version while your tab stays open.

Built into every HTML file
Tailwind CSS, zero build
- Write Tailwind classes straight in your HTML with no build step.
- Edit source directly in browser DevTools or the built-in code editor.
Version history & guards
- Restore in one click to the version created on every save.
- Overwrite guards catch stale tabs before they clobber newer changes.
Collections & dashboards
- Public submission form when you mark a folder as a Collection.
- Private owner dashboard that updates live out of the box.
Multi-tenant HTML files
- Turn on signups for any public HTML file.
- On paid plans, every user who signs up gets their own editable copy on its own subdomain.
Fork & upgrade templates
- Copy any public HTML file with one click to make it yours.
- Pull new template versions when an author ships an update without losing your own data.
Open public-domain spec
- Open specification with conformance tests.
- Independent hosts so your HTML files outlive any single vendor.
Share one link, broadcast live updates, and query any page as JSON
Let a friend edit from a secret link, with no account.
Generate a share link or QR code that grants editing access right away, and revoke it anytime. Everyone on the page sees saved changes appear live with focus and inputs intact.
Revocable link & QR code
Live multi-user sync
Update your site from your phone in seconds.
Because the editor lives in the HTML file itself, you can open your site on your phone, update a line, and save.

Change a number on the page and its JSON data updates.
Describe what on your page is data with a small rules tag, and Hyperclay publishes clean JSON at a stable URL on every save.

No separate database
Share one live page instead of trading attachments with your team.
Give everyone one live HTML file to keep open instead of trading emails and chat messages. When someone saves a change, every open copy reflects it right away without a refresh.

Your software shouldn't live in a silo.
-
You rarely control your own software.
You see what would make your software better. Yet the real app sits behind a brick wall, wired to servers, databases, accounts, APIs, and templates you cannot touch.
-
Building it yourself means fighting the stack.
Leaving an existing system forces you to coordinate databases, APIs, accounts, and templates yourself. All that machinery pushes you back when all you want is to edit the page.
-
What if one file held everything?
Imagine a single HTML file that travels with you and holds its own interface, behavior, and content. User actions, UI state, and app logic all live right inside the page.
-
Self-saving HTML files cut the cords.
With ClayJS, an HTML file becomes software that edits and saves itself. Cut the wires to separate servers, databases, and templates, and own the working app.
