1. The GIMP

The GIMP is a open source free graphics program that you can use to create and edit almost any type of graphics. It has support for Skins, and is pretty much a open source version of Adobe Photoshop.
2. Nvu

Nvu is a free open source web editor. While it doesn’t have all the features and interfaces of DreamWeaver or Sharepoint, it does allow you to edit code and design at the same time. It also allows you to move design elements without looking at any of the design code.
3. Open Office

If you run any spreadsheets (for billing for example) or save documents in Word format, Open Office is a world-renowned open source editor that supports almost all of the futures of Microsoft Office at a great cost-free. The interface is similar and you get almost the exact same results as you would using any Microsoft program.
4. Firefox

While Firefox in and of itself is great, the plugins that go with it, turn it into a formidable web development and debugging tool at a great cost. See our top 10 great plugins for firefox.
5. WinSCP

If you find yourself using telnet, ssh, scp and other file transfer protocols, you may be using a paid file transfer program. WinSCP is completely free open source program and supports multiple sessions, different protocols and can store sessions, usernames and passwords.
