A development environment is required by software developers and web designers to create, test, and deploy websites and applications. It is not necessary to develop all the apps in-house; it is possible to hire software developers instead.
Development environments typically include integrated development environments (IDEs), editor windows, command lines, code editors with syntax highlighting, text editors with word wrapping and snippets, debugging tools like a breakpoint tool or the ability to step through code line by line in a debugger. They also usually include an integrated version control system for easy branching and merging of changes.
