The fastest way to edit HTML visually in your browser

This is an interactive HTML editor and renderer for anyone who wants to change a web page without writing code by hand. Open any local .html file, see it rendered live, click an element to select it, drag a new block in from the sidebar, type to edit text, and hit ⌘S to save the file on your disk. It's a free, open-source alternative to tools like Webflow, Pinegrow, and BlocsApp — minus the paywall and minus the server round-trip.

Frequently asked questions

What is an interactive HTML editor?

An interactive HTML editor lets you edit a web page visually instead of writing raw HTML. You see the rendered page, click to select elements, drag to rearrange them, and the underlying HTML updates as you go.

Is this HTML editor really free?

Yes — 100% free, MIT licensed, open source. There is no paid tier. The code is on GitHub.

Does it work offline?

The first page load needs internet (it lazy-loads CodeMirror from a CDN for source mode). After that, visual editing of local files works without a connection.

Which browsers are supported?

Any modern browser can use the visual editor with import/export. Live "save to disk" requires Chrome, Edge, Arc, or another Chromium-based browser with the File System Access API.

Do my files get uploaded anywhere?

No. Everything runs locally in your browser. The editor is a static site — there is no backend.
