How to Preview HTML Files Directly on GitHub (With 1 Click)
Stop cloning repositories just to check your layout. Learn how a simple, lightweight Tampermonkey userscript adds a 1-click preview button directly onto your GitHub code view page.
If you are a front-end developer, UI designer, or open-source contributor, you know this annoyance all too well: You browse to a .html file inside a GitHub repository, wanting to quickly verify a layout or see a static web page asset in action.
Instead of a live preview, GitHub serves you a wall of raw code text.
To actually see the page, you are left with two choices: either clone the entire repository locally or manually extract the URL into an external rendering service. It is a subtle but continuous speed bump in a developer’s daily workflow.
To wipe out this friction entirely, I built a lightweight browser tool that gives you immediate, interactive visual feedback right where you work
I built a lightweight Tampermonkey/Violentmonkey userscript that seamlessly injects a floating, modern “Click to Preview” utility button right into your GitHub UI whenever you view an HTML file.
One click instantly previews your live rendered page directly in the same browser tab.
✨ Key Highlights:
🚀 Zero Configuration: Works instantly upon installation.
⚡ SPA-Friendly: Handles GitHub’s dynamic single-page navigation seamlessly (no annoying page refreshes needed to toggle visibility).
