IDEs

PYTHON IDEs (ride the snake)

• Komodo Edit
  Komodo Edit (currently version 5) is a free version of Komodo IDE that is simply the best.
• Pydev
  The good as always Eclipse IDE has great Python integration with Pydev

.NET IDEs

• SharpDevelop 2 (3 almost released)
  Open Source IDE that is very light weight and has many very useful tools such as language conversion utilities, licenses, snippets, able to read VS projects etc. In my opinion its great for coding .NET libraries but not webs.
• Visual Studio
  All versions of this tool going back to version 6 and C++ are really good. If you develop in .NET this is the tool. If you can’t afford the full package you can get VS Express.
• Dreamweaver
  Dreamweaver next to notepad is the most versatile front end, layout and file management tool out there.

FLASH IDEs

• Flash Develop
  Open Source IDE built off of SharpDevelop libs, .NET framework required.
• SE|PY
  Python based IDE cross platform
• Dreamweaver
  Great for editing as files and dealing with the front end interface hookup of flash and XHTML.
• Of course Flexbuilder for Flex and many others.

Java IDEs

• Eclipse
  Open Source tool that is a bit bulky but it was a direly needed tool in the Java world where IDEs are subpar.
• Dreamweaver
  Dreamweaver works great for dealing with .jsp files or the front end of the java applications that you may be building.

Javascript IDEs

• Dreamweaver
  Dreamweaver is a great front end javascript tool because it has code completion and it a fast js editor. There are many other free editors out there but dreamweaver seems to help you be more productive.
• JSEclipse
  JSEclipse is new from Adobe Labs that they bought from Interakt it is probably more bulky than you need as most Eclipse based apps are) but it looks promising.

PHP IDEs

• PHPEclipse
  Open Source IDE built off of Eclipse core.
• Dreamweaver
  Great for editing as files and dealing with the front end interface hookup of flash and XHTML.
• Komodo, PHPEd, etc all reviewed here
