Borrax HTML

View .html / .htm files stored inside your Obsidian vault — with working links, CSS and scripts.

Open any HTML file in your vault and it renders in a sandboxed frame, loaded directly from its vault location, so relative stylesheets, images, scripts and links all resolve correctly.

Features

• Opens .html and .htm files in a dedicated view (just click the file).
• Desktop: the file is loaded directly (file://) in an isolated Electron <webview>, so it renders exactly like opening it in a browser — linked CSS, inline <style>, scripts, links and external web fonts (Google Fonts, etc.) all work.
• Mobile: falls back to a sandboxed iframe with an injected <base> so relative CSS/links still resolve.
• Links to other files in your vault open inside Obsidian (same tab or a new tab — your choice); external links open in your system browser.
• Adjustable zoom level for rendered HTML.
• Optional "H" badge on folders that contain an index.html (click to open it).
• Right‑click the tab → Reload HTML or Open in external browser.

Installation

Manual

1. Download main.js, manifest.json and styles.css from the latest release.
2. Copy them into <your-vault>/.obsidian/plugins/borrax-html/.
3. Reload Obsidian and enable Borrax HTML in Settings → Community plugins.

From source

npm install
npm run build

This produces main.js. Copy main.js, manifest.json and styles.css into the plugin folder.

Security note

HTML is rendered exactly as in a browser: on desktop in an isolated <webview> (no Node integration, separate from your vault), on mobile in a sandboxed iframe. Scripts run just like in a browser, so only open HTML files you trust.
