open source software

Freely shared code

Open source software is computer software whose source code is publicly available and can be freely used, modified, and distributed.

The openness allows anyone to inspect how the program works, fix bugs, or adapt it to their needs.

Major examples include the Linux operating system and the Firefox browser.

Open source contrasts with proprietary software, where the code remains secret and controlled by the company that created it.
