# I Built Code Lab Sandbox: A Lightweight, Zero-Setup Web Code Editor

[#javascript](https://dev.to/t/javascript)[#webdev](https://dev.to/t/webdev)[#showdev](https://dev.to/t/showdev)[#frontend](https://dev.to/t/frontend)

When I want to quickly test an HTML structure, try out a CSS layout idea, or debug a JavaScript snippet, opening a heavy desktop IDE or setting up a local build environment often feels like unnecessary friction.

To solve this, I built Code Lab Sandbox—a clean, lightweight, zero-setup web code editor that runs entirely in your browser.
