Open source software (OSS) is software distributed with its source code, allowing for its use, modification, and distribution with its original rights. Source code, typically unseen by users, is manipulated by programmers to control program behavior. Access to source code enables changes, additions, or fixes. OSS often includes a license permitting modification to suit specific needs and distribution control.

Open-source solutions offer small businesses cost-effective alternatives to proprietary software, providing flexibility, customization, and community support.

Open-source software can provide collaborative, effective and secure solutions for users. Open source software is developed in a decentralised and collaborative way, relying on peer review and community production. Open source software is often cheaper, more flexible, and has more longevity than its proprietary peers because it is developed by communities rather than a single author or company.
