I am creating a Chrome extension. I am already familiar with JSFiddle, but this does not test Chrome extensions.

Is there a JSFiddle-like text editor (no download) which will let me build and test Chrome extensions?

Please do not suggest Notepad ++ or TextWrangler.

Personally, I would test on my own server, in order to have full control.

If you run Linux, then you already have Apache. If you run Windows, get a free WAMP, such as XAMPP (which I have used for many years and can highly recommend), which will run Apache on Windows.

Then you can serve test pages from localhost and debug your Chrome extension using those.

[Update] Since you use a Chromebook, check out:

  • A Web Server for Chrome, serves web pages from a local folder over the network, using HTTP. Runs offline.

(this might be the easiest option)

    Thank you for your answer! Unfortunately, I am on a Chromebook. I'll edit to include this detail. Commented Feb 16, 2017 at 12:36
  • Given that ChromeOS is Linux based, you might well have, or be able to install, a local Apache server. Testing on localhost is probably the best way to go about it.
