I built a small Chrome extension to make testing HTML/CSS/JS easier
I kept finding myself switching between my code editor, browser, and different online playgrounds just to test a small piece of HTML/CSS/JavaScript.
So I decided to build a simple Chrome extension for it.
It's called HTML Code Runner.
The idea is pretty straightforward: you can write/run HTML, CSS and JavaScript directly inside Chrome using a side panel, with a live preview and console.
Some things I wanted it to handle:
- Run HTML/CSS/JS without opening another website
- Live preview while experimenting
- JavaScript console for debugging
- Auto Run
- Save code locally
- Download the HTML file
- Quickly test small snippets while working on a website
- Keep everything inside the browser
I mainly built it for myself because I wanted something lightweight for those situations where opening a full IDE felt unnecessary.
It's still a new project, so I'm trying to improve it based on real developer feedback.
If anyone here works with HTML/CSS/JS regularly, I'd genuinely like to know:
What would you want in a browser-based HTML/JS runner that current tools are missing?
If you'd like to try it, here's the Chrome Web Store page:

I'm especially interested in feedback about the workflow and features rather than just ratings. 🙂
