Mercury Editor is a fully featured editor much like TinyMCE or CKEditor, but with a different usage paradigm. It expects that an entire page is something that can be editable, and allows different types of editable regions to be specified.

It displays a single toolbar for every region on the page, and uses the HTML5 contentEditable features on block elements, instead of iframes, which allows for CSS to be applied in ways that most other editors can’t handle. Mercury has been written using CoffeeScript and jQuery for the Javascript portions, and is written on top of Rails 3.1.

Aloha Editor is an advanced browser based Editor let’s you experience a whole new way of editing. It is designed to be the easiest to use, the fastest in editing and the best in its functions. The floating menu offers you the right options matching your editing context. The menu floats to the paragraph, table or content element you are editing. Thus the menu is as near as it can be.

Aloha Editor is ready to use when your website is loaded. Even if you need 20 or 100 input areas, Aloha Editor is loaded only once. Most of the other Editors use iframes and need to reload the Javascript and CSS for each instance. Aloha Editor does not need iframes. This results in saving up to 80% of the loading time compared to other editors.

GIMP is a free Photoshop substitute that will satisfy all but the most demanding professional graphic designers. If you need to make simple web graphics, retouch a few product photos, or create flyers or other marketing materials, this program should work nicely for you. It’s robust, and if you’ve used Photoshop or Photoshop-like clone programs, the interface and commands will be familiar to you. The images you create can be saved in an array of common formats, including PSD Photoshop files, in case you need to send your files to a Photoshop user.

All in all, GIMP might be the single greatest money-saver on this list. It’s completely free, whereas a single Photoshop license — which you’ll need to pay for again each time Adobe releases a new version of the software — can cost hundreds of dollars per user.
