4coder differentiates from other editors by focusing on powerful C/C++ customization and extension, and ease of cross platform use. This means that 4coder greatly reduces the cost of creating cross platform development tools such as debuggers, code intelligence systems. It means that tools specialized to your particular needs can be programmed in C/C++ or any language that interfaces with C/C++, which is almost all of them.
In other words, 4coder is attempting to live in a space between an IDE and a power editor such as Emacs or Vim.
