Simple and effective UI that is easy to use.

I can use it from a browser anywhere. I'm a Chromebook user so a cloud-based service is ideal for me. It's a pretty good basic code editor. It handles SFTP and SSH connections which is handy. I've tried other alternatives like Shift Edit but found them buggier (although CodeAnywhere has some bugs too).

The most important is that you can use the tool anywhere from your Browser. I use it for FTP connection to my PHP sites and coding when I do not have my local editor. You can also use it when the FTP is disabled on the network.
