Do I need to install anything to use Spaces?

No. Everything runs in the browser, so you can start from a template, edit the files and publish without setting up an editor, a build tool or a server on your machine.

Can I use my own domain with a Space?

Spaces gives each site a public address as soon as you publish. Whether you can point a domain you own at it depends on your plan, so check the current options before committing a domain to it.

Is Spaces suitable for a real website?

It suits static sites well: portfolios, documentation, landing pages and project demos. Anything needing a database, server-side logic or background jobs is beyond what a browser-published static site can do.

Hyring Spaces

Spaces is a browser-based tool that lets you build, run, and share small web projects instantly, without installing any software or setting up hosting.

What Spaces Is

W3Schools Spaces is an in-browser environment for writing HTML, CSS, and JavaScript (and a few other project types) and seeing the result immediately, without installing an editor, a local server, or any hosting account. You open a browser tab, write code, and watch it run.

A code editor that runs entirely in your browser
A live preview that updates as you work
A public link you can share so others can view your project
No local installation, server setup, or hosting account required

Why It Exists

Setting up a local development environment - an editor, a way to serve files, maybe a build tool - takes time before you've written a single line of useful code. Spaces skips that step entirely, which makes it well suited to quick experiments, following along with a tutorial, or putting together a small demo to show someone.

Task	Local Setup	Spaces
Getting started	Install editor, server, dependencies	Open a browser tab
Seeing a change	Save file, refresh browser	Preview updates automatically
Sharing your work	Deploy to a host or send files	Send a public link

Note: Think of Spaces as a scratchpad for the web: great for learning, testing an idea, or showing a demo. For a real production website, you'll still want proper hosting.

Spaces belongs to the same general family of tools as browser-based code playgrounds like CodePen, Glitch, or Replit: an editor and a live preview combined into one page, with sharing built in.

Good for: learning exercises, small demos, quick prototypes, sharing a snippet with someone
Less suited for: production websites, large applications, anything needing a custom domain or serious backend infrastructure

The rest of this section walks through creating a Space, choosing a starting point, working in the editor, and sharing what you build.
