open source


1. published source code of a software development project.

2. a software development approach based on published source code. Open source offers the possibilities of volunteer programmers and detailed troubleshooting by power users.
For some projects, this can lead to faster development and improved accuracy.
On the other hand, open source implies the loss of any competitive advantage that secrecy of source code might offer. For some kinds of projects, open source also presents increased security risks.
