dom2url

Don't wanna setup hosting for every microsite you need? Now you can build a microsite using just a URL. The microsite will live in your bookmarks forever!

Example

Editor

Open editor.html to write HTML in a split-panel editor with live preview. Click Run to generate a URL, then use the Copy button to grab it.

How It Works

dom2url encodes an entire HTML page into the URL’s hash fragment—no server, no database, and no hosting required.

1. HTML to instructions — the editor parses your HTML and converts it into a compact instruction set (E create element, A set attribute, T add text, ^ close element).
2. Compress — the instructions are compressed using deflate-raw via the browser's built-in CompressionStream API.
3. Base64url encode — the compressed bytes are encoded into a URL-safe base64 string and appended as the #hash fragment.
4. Render — when someone opens the URL, index.html reads the hash, decompresses it back into instructions, and executes them to rebuild the DOM.

The hash fragment of a URL is never sent to the web server, making it privacy-compliant by design. However, be careful: anyone you share the link with can read its contents, as it is not encrypted.

Versioned deployments

Each release is automatically deployed to GitHub Pages under its own directory (e.g. /v1/, /v2/), so older links keep working forever. A /latest/ symlink always points to the most recently deployed version tag (v1, v2, …).

Offline

You can also clone repository to your device, than use index.html to open your links even without internet connection.
