A programming tool or software development tool is a computer program that is used to develop another computer program, usually by helping the developer manage computer files. For example, a programmer may use a tool called a source code editor to edit source code files, and then a compiler to convert the source code into machine code files. They may also use build automation tools that automatically package executable program and data files into shareable packages or install kits.

Not to be confused with Programmable tooling.

A set of tools that are run one after another, with each tool feeding its output to the next one, is called a toolchain. An integrated development environment (IDE) integrates the function of several tools into one program. Usually, an IDE provides a source code editor as well as other built-in or plug-in tools that help with compiling, , and .
